An important part of bioethics is risk assessment, the analysis and prediction of risks. Bioethics combines risk assessment, the concept of avoiding harm, with an assessment of benefits, the concept of doing good or beneficence. There are various risks of genetic engineering, for example the risk of unintentionally changing the genes of an organism, the risk of harming that organism, the risk of changing the ecosystem in which it was involved, and the risk of harming the ecosystem, and the risk of change, or harm, to any other organism of that species or others, including human beings (who may even be the target of change). The concept of risk in biotechnology involves both the potential to change something and the potential to harm. The extent to which a change is judged to be a subjective harm depends on human values, whether nature should be "intransient" or modified. This relates to the fears that technology is unnatural.
The risk to change organisms or ecosystems, which may not involve "harm", the standard meaning of risk, makes genetic engineering more complex. Many want to protect nature, not because of its value or property, but simply because it is there. The concepts and images that the words "life" and "nature" imply are similar in different countries (Macer, 1994a). Related to this is the concept of biodiversity, which is now legally recognised as a good in the Biological Diversity Convention, primarily because of economic potential, but it is also protected because of aesthetic value. Biodiversity is a word used to picture the great diversity of living organisms on the planet. Just as the individual processes of life are dynamic, so is the composite of the lifeforms. The idea of dynamism also implies a balance, and this extends the framework that risk must be pictured in.
Rather than calling the ideas of benefit, risk, autonomy and justice, etc., bioethical principles, we could call them ideals (Macer, 1994a). These ideals all need to be balanced, and the balance varies more within any culture than between any two. Ideals need to be included, together in a balancing act that fits reality. Surveys combined with observations of policy and behaviour in different countries allow us to look at how these principles and ideals are balanced. An examination of history also shows how the balancing act has varied in different times and places. In another paper I have discussed what is ethical biotechnology (Macer, 1995).
Bioethics considers the ethical issues raised
in biology and medicine, and especially those raised by human
activity in society and the environment using biotechnology (Macer,
1990; 1994a). Bioethics is a concept of "love", balancing
benefits and risks of choices and decisions. It considers all
living organisms and the environment, from individual creature
to the level of the biosphere in complexity. All living organisms
are biological beings, and share a common and intertwined biological
heritage.
Bioethics in History
The word "bioethics" comes to us only from 1970, yet the ideas and concepts that word encompasses come from human heritage thousands of years old. This heritage can be seen in all cultures, religions, and in ancient writings from around the world. The relationships between human beings within their society, within the biological community, with nature, and God, are seen in prehistory, therefore we cannot precisely define the origins of bioethics. Human civilisation has been tied to agriculture for many millenium, and the concept of bioethics first emerged in the relationships that people had with nature, a nature which could be cultivated to provide for human needs. For example, the decision to burn a forest and plant a crop is a bioethical decision. There is risk in the decision to burn or not to burn, and initially the judgement would be based on practical outcomes. If one area of forest was burnt and the land planted for several years with crops which then later failed, if the population density was low enough the group could move on to burn the next area of forest, and farm that. A gradual circle could be established, if the forest fires were contained. The risk of ecological damage is offset by the risk of lack of food, or by desire for a particular way of life. The decisions of how to use land, and nature, part of environmental bioethics, are not new. Neither is medical decision making, and the questions of abortion and euthanasia are evident in archeology and written records for millenia as well.
In the conclusion of an earlier book, Shaping Genes (1990), I said that we have much to learn from the issues raised by genetic technology, not just the nature of our genes and the effects they have on us and other organisms, but the nature of our thinking about what is important in life. When we consider genetic engineering we can also consider the factors which affect our decision to use a given technology, some of which may have been taken for granted in the use of more traditional forms of agriculture or industry.
There are also lessons to be learnt about concepts of risk assessment, because genetic engineering is a technology associated, and perceived to be associated, with both benefits and risks (Macer, 1992a; 1994a). One class of risks associated with genetic engineering is of relatively high probability but low consequence. For example, the transfer of a gene for insect resistance to a neighbouring wild species of plant is likely if huge areas of land are being farmed, however, it would have little consequence to the farm or agriculture. We also have the risk of insecticide resistant insects, to which better strategies can be used to lower risk. Strategies to lower chances of resistance to Bacillus thuringiensis insecticidal protein include the patchwork farming of treated and untreated fields, and methods to reduce the amount of untreated fields (that may suffer more insect attack!) by computer simulation have been devised (Alstad & Andow, 1995). Another class of risks would be low probability, but high consequence, for example gene transfer to human beings that affected health; or escape of an vaccine-producing animal from a battery farm that contained infectious fatal virus. In the past we have seen numerous examples of new organisms and biological control agents, which have shown us that the most common result is that the agent does not work, however a reasonable number do work (e.g. 10-20%). The risk comes from the few that have unexpected undesirable effects in an ecosystem, which is more common for introduced agricultural production species than for the biocontrol agents. The reason that biocontrol agents have been less risky is that better assessment of the benefits and risks has occured, than from the earlier centuries often blind introduction of new organisms.
Genetic engineering has been a catalyst for
thinking about risk assessment and bioethics since its invention
in 1974. However, the issues raised are not fundamentally different
to those of the past (Macer, 1993) and I would reject the use
of the word "Genethics" which has been a recently coined
term (e.g. Suzuki & Knudtson, 1993). For example, to chose
what plant species would be suitable as an agricultural crop,
to select it, and to cross it, has been done for millenia and
saw the adoption of a hybrid of three species, wheat, as a staple
of one part of the world. The speed at which change in characters
can be broad about is faster with genetic engineering than traditional
breeding, however, it does not have such a unique power of change
as the special term, "Genethics" would imply. The greatest
ecological change in the world is the age old agent of change,
deliberately set fires. The most powerful force underlying this
would arguably be the often unforseen consequences of a growing
population of human beings.
Descriptive and prescriptive bioethics
There are two basic ways to approach bioethics, one being descriptive and the other being prescriptive. One describes how people make decisions, and the other recommends the process that can be used to make decisions, and/or the range of decisions that can be made. Descriptive bioethics includes the use of observation, and surveys, to describe the choices that people make. To make good choices, and choices that we can live with, improving our life and society, is certainly a good thing. However, what is good for one person may not be good for the broader society, and the global nature of agricultural economics and environmental impact, mean we have to think far beyond the small field trial of a genetically modified organism (GMO). The choices that need to be made in the modern biotechnological and genetic age also extend from before conception to after death - all of life.
Prescriptive bioethics involves calls for certain factors to be included in decision making, certain groups of people to be involved, and even for certain decisions to be made, or at least a range of socially tolerable decisions. When it comes to risk assessment, the same distinction applies. We can describe the ways risks are perceived, and we can also call for certain risks to be included in an assessment, and for certain weight to be given to these risks. Different groups of people and countries may call for different levels of risk assessment, and in what constitutes a significant risk (von Schomberg, 1995). The legal tolerance limits of acceptable risk and harm are already broadly outlined in international covenants such as the Declaration of Human Rights, and international treaties on environmental protection which include limits on the permitted damage to the common environment, such as the convention on ozone-damaging chemicals, and on deep sea dumping.
There are calls for global laws on genetic engineering to join this list of international laws, to strengthen the weak consensus found between international regulations on GMO release. Agriculture is dependent upon water, and environment, which are sometimes shared resources between different countries. Most maritime nations have declared 200 mile limits within which they claim prior rights to exploit marine resources, and the many examples of over-fished species illustrate the need for international fishing strategies, and also makes us especially cautious about the use of genetic engineering in marine aquaculture. Even on land, weeds and pest animals may spread rapidly in many cases.
Surveys are useful for descriptive bioethics, in fact they are one of the most reliable methods if performed and analysed carefully. However, their role in prescriptive bioethics depends upon a number of factors: does the group surveyed represent the population, should the opinions of that group make decisions, can we trust that group whether it be the public, product consumers, scientists, politicians or farmers? Also, there are some principles which may be commonly perceived to be good, but are commonly ignored in daily life, for example, equal human rights, looking after the poor, and respect for the environment. Even the interpretation of surveys is clouded by the fact that leading questions can be used by surveyors who want to make different points.
To examine whether global guidelines are useful,
and representative of descriptive bioethics, we can attempt to
look at basic universal ideas that people use in deciding these
issues (Macer, 1992a; 1994a). Differences and similarities in
risk perception are seen within any group of people within every
society. Data from opinion surveys and observation suggests that
the diversity of thinking within any one group is much greater
than that between any two groups. In other words, in every group
we may find the complete range of opinions from yes to no, and
the reasoning behind these decisions. The diversity of comments
is therefore a microcosm of the total picture. Furthermore,
the social environment that people grow up in, and the education
strategies in different countries, are becoming more similar making
the shared environment more similar. This suggests that a universal
approach to regulation which is consistent with people's values
is even more representative now than it was a century ago.
II. Descriptive bioethics and perceptions of risk
There are several ways to observe or describe bioethics. Observations of culture and society are useful, but to avoid the dangers of mixing the descriptive and prescriptive elements of bioethics through the biased interpretation of subjective experiences, random surveys allow somewhat more quantification. World-wide there have been quite a number of surveys focusing on biotechnology (Zechendorf, 1994). There are some consistent national tendencies over the degree of risks that people perceive from biotechnology even in Europe (Eurobarometer, 1991; 1993), so it is interesting to ask the questions among more diverse countries. In 1993 an International Bioethics Survey was performed across ten Asian-Pacific countries of the world (Macer, 1994a). The degree to which actions of individuals, and also society, can be both described and predicted by surveys can only be determined after surveys are conducted. A written survey allows more thinking on issues, than an interview. Also multiple choice answers can be leading, hence the use of many open response questions. The use of surveys is only one part of the overall approach we can use to look at cultures, however, the data from surveys must be explained by any description of the real world.
Another part of the data that we can use for
evaluating public perceptions is the use of the products, and
we can see current practices in agricultural biotechnology by
the preferences of farmers, consumers and what sort of products
companies produce. Analysis of the factors relevant to these
groups that are behind their perceptions is important. For example,
the consumption of products of new biotechnology can be best seen
from the results of the sales of these products in supermarkets,
and their acceptance by the farmers who first use them. However,
the factors involved in their decisions require surveys to evaluate,
for example why they chose to use them over other alternatives,
and why people chose not to use them.
Survey strategies
There are various survey strategies. The first type is the use of fixed response questions, to chose from set answers, and this has been done in the USA (OTA, 1987; Hoban & Kendall, 1992); and Canada (for the Canadian Institute of Biotechnology by Decima, 1993). There has also been comparative studies of scientists in USA and in Europe, looking at their perceptions of the public image of genetic engineering (Rabino, 1991; 1992). The Eurobarometer is a regular public survey in Europe, including different questions each time, and is conducted in all 12 countries of the European Community. In 1991 Eurobarometer 35.1 looked at biotechnology and genetic engineering, and in 1993 Eurobarometer 39.1 repeated the same questions. The Eurobarometer poll is limited because of the relatively small number of questions, and also the set format of the questions, but is the most comprehensive in terms of sample response, randomness, size, and number of countries. There is some diversity within Europe, in biotechnology policy, public acceptance, and regulations.
Recent survey strategies in Europe attempt to look at reasoning more than just statistics (Hamstra, 1991; 1993) which may shed more light on the factors which will affect policy development. There has been attention on qualitative survey approaches to look at factors used in decision-making, which can be useful to identify the range of factors that people use. Ideally they need to be combined with some quantitative measurement to discover which are the most common issues. However, by finding all the issues that people can think of, one can trace out key issues which are behind concerns. There is also a question of which group within society is involved in policy and opinion-making. Martin and Tait (1992), conducted surveys of selected groups of the UK public. They conclude that groups with an interest in biotechnology have probably already formed attitudes to it, which are unlikely to significantly change these. They looked at industry and environmental groups, and local communities, which are major players in the development of policy at both national and local levels. They also suggest that people with the least polarised attitudes are most open to multiple information sources.
In New Zealand there was a study using both
set and open questions in 1990 (Couchman & Fink-Jensen, 1990).
In Japan there have been several studies, the most comprehensive
of these being a study that I did in 1991, among public, academics,
scientists, and high school teachers, in which I also reviewed
all the previous studies in Japan (Macer, 1992a). From the results
of open questions, it was found that some arguments that are often
used in biotechnology debates, such as eugenic fears or environmental
risk, are not the most common concerns voiced by people in open
questions. The more common concerns are interference with nature
or general broad fear. The use of open comments also found a
great diversity and depth of comments were seen among the public,
with as much diversity as those expressed by scientists. The
survey found that many people perceive both benefit and risk simultaneously,
they are attempting to balance these, which suggests that factors
which alter this balance will change the depth of net support
or rejection of a technology. Also I found that educated people
show as much concern, in fact biology teachers considered there
was more risk from genetic engineering than the ordinary public
(Macer, 1992b, 1994b). The risk perceptions among scientists
had some tendency to be more concrete than in the public, but
all groups expressed a considerable variety of concerns.
International Bioethics Survey
The International Bioethics Survey was performed in 1993 in ten countries of the world, in English in Australia (A), Hong Kong (HK), India (IN), Israel (IS), New Zealand (NZ), The Philippines (P) and Singapore (S); in Japanese in Japan (J); in Russian in Russia (R); and in Thai in Thailand (T) (details and collaborators are in Macer, 1994a). Public and student questionnaires were identical. The teacher's survey included some of the same questions, but half of the questions were about teaching and curriculum in bioethics and genetics (Macer, 1994a). The randomly distributed surveys to public and teachers were sent with stamped return envelopes, and people were asked to respond within each country with no reminders.
The International Bioethics Survey focused on agricultural biotechnology, and medical genetics, with some other questions looking at environmental attitudes and attitudes to disease. The questionnaires included about 150 questions in total, with 35 open-ended questions. The open questions were designed not to be leading, to look at how people make decisions - and the ideas in each comment were assigned to different categories depending on the question, and these categories were compared among all the samples. In total nearly 6000 questionnaires were returned from 10 countries during 1993 (Macer, 1994a). General information gathered in the surveys included sex, age, marital status, children, education, religion, importance of religion, race, income and rural/urban locality, and some data are in Table 1.
Results of the other questions, further background,
and more examples of open comments have been published (Macer,
1994a). In this paper the word "significant" implies
a statistical significance of P<0.05. The funding for these
surveys came principally from the Eubios Ethics Institute, with
some assistance from the ELSI (Ethical, Legal, and Social Impact
issues) group of the Japanese Ministry of Education, Science and
Culture Human Genome Project, and The University of Tsukuba.
The high school samples in Japan are supported by the Ministry
of Education, and are part of a longer term project to develop
high school materials to teach about bioethical issues in the
biology and social studies classes.

1J91 from Japan 1991 survey (Macer, 1992a, 1992b).
Table 2:
Perceptions of benefit (Q6) or risk (Q7), and open comments about
genetic engineering
One of the factors that may relate to risk
perception is knowledge of science, and the claim that increased
knowledge is correlated to decreased perception of risk has been
suggested in some other studies (OTA, 1987), and is a commonly
held view in academia and industry. In this 1993 study most respondents
answered that they had some interest in science and technology,
with few saying they did not. Another measure may be the response
rate, which was generally between 20-30%, significantly higher
than commercial mail box response. The 1991 Japan surveys suggest
that knowledge of science is not so closely correlated with response
rate (Macer, 1992a; 1994a). An indirect measure of the depth
of knowledge were the comments that were given in response to
open questions.
The results of the awareness question for
pesticides, biotechnology and genetic engineering in the International
Bioethics Survey are shown in Table 1. It is interesting that
biotechnology was generally one of the most unfamiliar terms,
next to gene therapy, except in Japan, where it was one of the
most familiar, consistent with other surveys (Macer, 1992a).
The awareness of gene therapy was the lowest among the eight developments
included. Genetic engineering was generally the least familiar
among the other areas, with pesticides, in vitro fertilisation,
computers and nuclear power being most familiar. Awareness was
significantly related to educational attainment in most samples.
The samples with the greatest awareness were generally biology
teachers, next were medical students (New Zealand, Japan, Australia
and the Philippines), followed by the other groups, social studies
teachers, biology students and the public. For all developments
and in all samples, there was a positive correlation between awareness
and the expressed level of interest in science from the results
of the earlier question.
Following questions, discussed below, asked
them whether they thought each development would have a benefit
or not, and their perceptions about the risks of technology by
asking them how worried they were about each development. The
areas of science and technology included: In vitro fertilisation,
Computers, Biotechnology, Nuclear power , Agricultural Pesticides,
Genetic engineering. The results for genetic engineering are
shown in Table 2. For this question, the comments were assigned
into categories, and the results are shown. Both benefits and
risks were cited by many respondents.
There was more concern about genetic engineering
and pesticides, despite the lower familiarity with biotechnology.
The degree of concern depends upon what people know. People
do show the ability to balance benefits and risks of science and
technology, consistent with earlier surveys (Macer, 1992a; 1994b).
Bioethical maturity
People do not have a simplistic view of the
positive or negative face of science and technology, and can often
perceive both benefits and risks. Overall we do find a positive
view, but for different applications there are quite different
opinions. This balancing of good and harm is necessary for bioethics,
and I have called this one indicator of the bioethical maturity
of a society (Macer, 1992b; 1994b). The use of surveys can provide
us with some indicators of the degree to which society can make
well-thought out "mature" decisions, rather than impulsive
"childish" decisions based on immediate gain.
The types of concern that were expressed over
genetic engineering give us some picture of risk perception (Table
2). What is a risk? The idea of interference with nature is
an aesthetic, religious or moral concern. It presupposes that
it is bad to change nature, and is related to the risk of playing
God, that we are changing God-given nature or that we are exerting
God-like powers in the modification of nature. Eugenic, ethical
and social impact concerns are risks related to the most common
category of general human misuse. These extend from the type
of ethical concern that we should not modify animals, a type of
interfering with nature concern, through the concern that we should
not violate human rights, which is more universally accepted in
law as a risk. More vague concerns of risk are seen in the categories
of fear, and danger. The concerns of insufficient controls, it
is a waste of resources, or conversely that we can control technology
so we don't need to worry, are more concrete. Ecological and
health concerns are also more concrete.
By dividing up the concerns that people have
in such a way, we can form a better picture of what risk assessment
means in their minds. The same type of analysis was done in 1990
in New Zealand (Couchman & Fink-Jensen, 1990), and in 1991
in Japan among scientists, students, teachers, and the public
(Macer, 1992a). There is a trend for scientists to give more
concrete concerns, though in related questions on the risks of
genetic engineering of animals and humans, in that survey still
16% gave concerns that it was interfering in nature.
Therefore greater awareness of a technology
may not mean that the perceived risks are only technical. Risk
assessment in the minds of people includes aesthetic, religious
and moral concerns which are often vague. Rather than saying
that one class of risk perception is mature and another immature,
we could actually say that to appreciate the wide range of risks
is more mature than to only think of one or two.
We can expect the awareness of both benefits
and risks of products will grow with the increased use of biotechnology
products, and about 70-80% were already aware that genetically
modified organisms are being used to produce foods and medicines.
In all countries of the International Bioethics Survey there
was an overall positive view of science and technology, it was
perceived as increasing the quality of life by the majority in
all countries. Less than 10% in all countries saw it as doing
more harm than good (Macer, 1994a).
When specific details of an application are
given there is generally greater acceptance, suggesting that people
have some discretion, another indicator of bioethical maturity.
It also suggests that if details of a technology are given, for
example by the company or government related to the release of
a GMO, the public will show greater acceptance of an application
(Macer, 1992b; 1994a; Macer et al., 1995) This is illustrated
in questions looking at environmental release of genetically modified
organisms (Q31) which were taken from the OTA (1987) survey, with
comparisons to a question of Hoban & Kendall (1992). The
results are in Table 3. The approval of the Calgene FlavrSavr
modified tomato which has delayed ripening for general cultivation
in the USA was given by the USDA in 1993, and it was approved
for general commercial food consumption by the FDA in 1994, and
sold in the summer 1994 in some parts of the USA. The results
show that it would be generally supported around the world.
The healthier meat question is relevant to
efforts to make less fatty meat, both by hormones in pigs, and
other animals. In the USA in 1992, 45% said "acceptable",
32% "unacceptable" and 23% "don't know" to
a similar question (Hoban & Kendall, 1992). In a related
question on cows with increased milk, and in the USA in 1992,
36% said "acceptable", 41% "unacceptable"
and 23% "don't know" to a similar question in 1992.
This has become reality in 1994 with the general use of bovine
growth hormone (BST - bovine somatotrophin) in the USA dairy industry,
a hormone made by genetic engineering that can increase milk yield
by 10-20%. It also received less support in the International
Bioethics Survey than the goal of less fatty meat, which is consistent
with the widespread questioning of the need given the existing
milk surplus in some countries.
Animals have long been used for agriculture,
and are likely to continue to be used. The moral status of animals,
and decisions about whether it is ethical for humans to use them,
depends on several key attributes; the ability to think, the ability
to be aware of family members, the ability to feel pain (at different
levels), and the state of being alive. Causing pain is considered
bad, and it is the major guiding principle for animal treatment.
If we do use animals we should avoid pain. Animals are part
of the biological community in which we live, and we have to consider
the ethical implications of whether they possess autonomy. People
will continue to eat animals, and practical ethics must improve
the ethical treatment for all animals. This is a further area
of risk assessment that applies to animal use, the risks of unethical
treatment of organisms. People need to decide how much more they
are prepared to pay for better treatment of animals, such as the
costs of eliminating battery farming, or the costs in not using
new animal treatments that produce cheaper milk or meat such as
bovine growth hormone.
The highest degree of support among the applications
of genetic engineering that were given was seen for disease-resistant
crops, and bacteria to clean oil spills (Table 3). The sports
fish is an example of genetic engineering for fun - and it is
reassuring that many people reject such genetic engineering.
The highest degree of support for the sports fish is in the USA
where 53% approved in a 1986 survey, while 73% approved of bacteria
to clean oil spills or disease-resistant crops (OTA, 1987). The
general support for products of genetic engineering seems to be
high, especially if they are claimed to be more healthy. In the
Canadian study comparisons between chemicals and genetically engineered
organisms usually found less support for chemical methods (Decima,
1994). In the 1991 survey in Japan an open question looking
at awareness, benefits, and risks of genetic manipulation of microbes,
plants, animals and humans, was asked (Macer 1992a; 1992b). The
responses made by the public, teachers and scientists were compared
with results from New Zealand (Couchman & Fink-Jensen, 1990),
and few differences were observed. As in the USA, human genetic
manipulation is associated with the most risks, and plant genetic
manipulation with the least, but unfortunately they didn't compare
open comments (OTA, 1987).
Table 3: Approval of environmental release of GMOs
Environmental concerns
Some environmental concerns were seen in the
responses to the general questions on genetic engineering and
biotechnology (Table 2). In the 1991 survey in Japan (Macer,
1992a) 49% of the public agreed that genetically modified plants
and animals would help Japanese agriculture become less dependent
upon pesticides, while 49% of teachers and 56% of scientists agreed.
71% of the company scientists agreed with this statement. Only
7% of scientists and the public disagreed with this, while 13%
of teachers disagreed. This is a major argument of those calling
for the development of genetic engineering in agriculture, and
the result suggests that it is supported by a majority of people,
though still many people are not sure about how they feel. This
statement was also supported by a majority of respondents in the
countries in the International Bioethics Survey (Macer, 1994a).
In 1990 European public opinion poll conducted
in the U.K., France, Italy and Germany, by Gallup for Eli Lily
(Dixon, 1991), the respondents were asked to choose the largest
benefit that they saw coming from biotechnology, between one of
four possible benefits from biotechnology. Over half rated cures
for serious diseases as the most important benefit. Another option
was reducing our dependence upon pesticides and chemical fertilisers,
which 26% of Italians, 24% of French, 22% of British and 16% of
Germans, chose as the largest benefit. The respondents were asked
a similar question about their largest concern. 40% of French,
35% of Germans, and 25% of British and Italian respondents chose
eugenics, and slightly lower proportions overall chose environmental
harm, 34% in Britain, 33% in France, 22% in Italy and 21% in Germany.
Potential health hazards from laboratory genetic research were
named by 29% in Italy, 17% in France, 11% in Britain and 10% in
Germany. Overall one third of respondents feel that biotechnology
is ethical and one third feel that it is unethical, and one third
think it is in between, "neither".
Therefore, it appears that in all countries
medical advances, and the ability to cure genetic diseases are
the major benefits people see from genetic engineering and biotechnology.
Environmental concerns are a close second, and this is consistent
with the International Bioethics Survey when we consider concrete
concerns. However, from the results of the open questions, we
also see lower proportions of the public cite these concerns,
and there are other common concerns including what is natural,
or ethical, as discussed above (Table 2). The benefits are divided
depending on the organisms that are considered. Microorganisms
are seen for both medical use and general use to produce useful
substances through fermentation. Plants and animals are seen
for their obvious agricultural importance, and genetic manipulation
is perceived for its ability to aid the breeding of new varieties,
and to increase production of food (Macer, 1992a).
There were also two open questions asking
what images people had of life and nature. The question on nature
followed several questions on genetic engineering, so it is not
surprising that many (about one quarter) included a comment that
nature is something that not to be touched by human beings, and
about one tenth mentioned ecological problems (Macer, 1994a).
The ethical limits of genetic engineering may in the end be decided
by subjective perceptions of "nature" rather than objective
environmental risk itself. Subjective concerns are very difficult
to define and this survey is an attempt to begin a search among
ordinary people around the world on what these limits might be.
We all have some limit, whether it be blue roses or chicken with
four legs - and we also realise these limits change through time.
A simple definition of bioethics, as I said earlier could be
love of life. It is essential to understand the images people
have of life in order to develop understanding of the bioethics
that people have. Public acceptance depends at least as much on
these types of concerns as on ecological or health risk, which
is an important point in discussion of risk assessment.
III. Risk assessment, bioethics and trust in
authorities
One of the central issues of ethics is decision-making,
that is who should make decisions, and who do people trust? A
question on the level of trust that people had in authorities
for information on the safety of biotechnology products was asked
in the International Bioethics Survey, as shown in Table 4. There
was most trust in the government in Hong Kong and Singapore, and
least in Australasia, Japan, Russia, USA and Europe. Despite
the lower trust shown in the government in Russia, they had a
level of trust in medical doctors. The result is most striking
when we compare it to Japan, in which doctors were not trusted.
In fact it appears Japanese do not trust anyone very much, but
the biggest difference with the other countries was that doctors
and university professors were mistrusted, especially so by medical
students. Whereas Russians show great trust in doctors and environmental
groups, and a high level of trust in professors. Companies were
least trusted everywhere. Farmers were also not trusted (unlike
the USA, where in 1992, 26% had a lot of trust, 68% had some trust,
and 6% had no trust in farmers (Hoban & Kendall, 1992). In
hindsight it would have been interesting to ask whether consumers
or the public can be trusted, and do people trust such crude transparent
democracy.
The lack of trust in companies or governmental
regulators is also seen in European (Eurobarometer 1991, 1993)
and North American surveys (OTA, 1987; Hoban & Kendall, 1992;
Rothenburg, 1994). This lack of trust is a concern. The most
trusted source of information are environmental groups. The main
source of information is the media in all countries (Macer, 1994a),
but people are becoming more selective in what they believe.
There are a variety of arguments calling for
public involvement in policy making. If we respect autonomy of
human beings we should respect their right to have at least some
property, or territory, and control over their own body. In agriculture
this means respect for freedom of growing what crops a farmer
chooses, and eating what food we like, within social constraints
(e.g. human flesh is a general taboo in most cultures). People's
well-being should be promoted, and their values and choice respected,
but equally, which places limits on the pursuit of individual
autonomy. We want to give very member in society equal and fair
opportunities, and equally share the risks in the application
of technology, this is justice. Utilitarianism (the greatest good
for the greatest number) is useful for general proportions, but
it is very difficult to assign values to different people's interests
and preferences. The concept of "society" includes
the future of society, future generations are also an essential
part of society, and ethically speaking we should protect the
environment for the future generations.
One of the underlying philosophical ideas
of society is to pursue progress. The most cited justification
for this is the pursuit of improved medicines or increased stable
food supply, which is doing good. A failure to attempt to do
good, is a form of doing harm, the sin of omission. This is the
principle of beneficence. This is a powerful impetus for further
research into ways of improving health and agriculture, and living
standards. It is therefore unacceptable to hold up the progress
of a potentially useful technology, unless the harms it may bring
are likely to be significant when compared to the benefits. Biotechnology
is challenging because, like most technology, both benefits and
risks will always be associated. A fundamental way of reasoning
that people have is to balance doing good against doing harm.
We could group these ideals under the idea of love, love means
to do good to others and not to harm others. We need to share
benefits of new technology and risks of developing new technology
to all people.
People in developing countries should not
be the recipients of risks passed onto them by industrialised
countries, despite the economic pressure to allow this. We can
think of the dumping of hazardous wastes to developing countries,
in return for financial reward, but the environmental and human
health consequences of dumping toxic waste cannot be measured.
Testing of GMOs is a similar case, though we must note the developing
country that is growing GMOs over the largest area is China which
is doing so for its own reasons. Industrialised societies have
developed safeguards to protect citizens, and some of these involve
considerable economic cost. While it may not be possible for
developing countries' governments to impose the same requirements,
they should not accept lower standards - rather all can use data
obtained in countries with strict and sufficient safeguards of
health, with the aid of inter-governmental agencies. Any basic
human right should be the same in all countries, and this is one
of the roles of the United Nations. Ethically this would support
the implementation of minimum international standards for regulation
of biotechnology (Krattiger & Rosemarin, 1994). This suggests
that risk assessment methods should become systemised and standard,
though as discussed in other chapters in this book, and as seen
in international comparisons, how to effect a system is still
contentious.
The precise outcome of interventions in nature
or medicine is not always certain. It has taken major ecological
disasters to convince people in industry or agriculture of the
risks. Introducing new organisms to the environment is also associated
with risk. If we introduce very different gene combinations into
the environment they could have major consequences, which may
be irreversible (Macer, 1990; see other papers in this book).
The new genes may enter other organisms, or the new organisms
themselves may replace existing organisms in the ecosystem. The
ecological system is very complex, minor alterations in one organism
can sometimes have effects throughout an ecosystem. Field trials
and experimentation are an ethical prerequisite before full scale
use of new organisms, as is the scheme used by the USDA in the
USA, and quarantine regulations used throughout much of the world.
In most interventions in life there are slippery
slopes. The idea is that because we perform some action, we will
perform another. Controls which were adequate for initial exploration
may fail under increased pressure. While we may not do any direct
harm with the application in question, it could result in progressive
lowering of standards towards the ill-defined line beyond which
it would be doing harm. The inability to draw a line is no measure
of the non-importance of an issue - rather some of the biggest
fundamental questions in bioethics and life are of this nature.
With precautionary laws to prevent risk because
of insufficient scientific knowledge, like the regulations on
field trials of GMOs, we could expect gradual weakening of control
as experience is gained to support reduced controls. However,
Jager and Tappeser (1995) in this book would argue that the data
from field trials does not support a relaxing of guidelines, as
has occured in the USDA and is being called for in Europe. In
this case it may be a slippery slope of increasing familiarity,
combined with an absence of dramatic incidents, rather than maintenance
of the same scientific objectivity as in the initial trials.
It may also be led by bureaucratic overload, and pressures for
commercial releases. In this case there are differences in the
interpretation of risk assessment data. It should also be noted
however, that the real safety test of GMOs is large scale commercial
releases, and some releases could be justified if a substantial
monitoring system was established to track the genes and ecological
impacts. In this case, an intermediate phase between large experimental
trials and full commercial release that was over the period of
several years would seem wise.
Some people, from all countries, say that
some developments of science and technology such as genetic engineering
are interfering with nature because "nature knows best".
However, we have some good reasons to interfere with parts of
nature, for example, we try to cure many diseases that afflict
humans or other living organisms and we must eat. A negative
science fiction image has been easily promoted and is appealing
to the human imagination. The fascination with creating "new
forms of life" is coupled to a fear of how far it might be
taken. There are many movies which play on scary themes, from
Frankenstein to the 1993 blockbuster movie Jurassic Park
brought genetic engineering into the imagination of many. These
are thought to be very powerful in shaping public acceptance and
perceptions, though just how influential is a question for research.
(Q29) Suppose that a number of groups made public
statements about the benefits and risks of biotechnology products.
Would you have a lot of trust, some trust, or no trust in statements
made by...?
IV. A future with public involvement in risk
assessment
We must ensure that efficient and sustainable
agriculture is encouraged, but recognise it is only part of a
broader solution. Sustainable agriculture could be defined as
the appropriate use of crop and livestock systems and agricultural
inputs supporting those activities which maintain economic and
social viability while preserving the high productivity and quality
of the land. We need to improve agricultural efficiency to succeed,
however current research interests in biotechnology are not necessarily
the best way to provide sustainable agriculture. Large corporations
are developing new techniques that may require constant application.
For example, biological weed control is more cost effective
and has a higher success rate than that achieved in searching
for useful agrochemicals, yet development is limited because it
may not make commercial profits.
The consequences of these decisions on the
different communities involved in agriculture also needs to be
considered, with a variety of social risks of new technology,
which could in the end be the greatest risk of manipulation of
life, as it will shape future public acceptance about the limits
to the type of interventions humans can make in nature. This
could be called social risk assessment, and it is an area that
social scientists will explore, using the tools of descriptive
bioethics.
Some of the criticism is against technology
in general, and needs balanced consideration. For example, there
are valid criticisms about the development of herbicide-tolerant
plants, that biological control is better, but they do have immediate
environmental advantages in some cases. For example, maize growers
make 4-6 herbicide applications a season, but if the crop was
tolerant to a broad-spectrum post-emergence herbicide only one
application would be needed. Reducing herbicide use and switching
to biodegradable products is consistent with sustainable agriculture
and is an important practical step in that direction, as long
as the powerful commercial interests do not prevent the eventual
widespread use of the ideal, biological control.
The ethical role of scientists is defined
by several levels of moral community: the scientific community
itself, the local community, the national society, and the global
society. Scientists are involved in a number of different relationships,
but first they are participants in society, having the same responsibilities
as any citizen. Scientists are also part of a profession, which
includes some moral responsibility. If the scientific profession
or community does not censor themselves others will do so. We
can see the trend for different groups or professions to lay out
their ethical codes, as written codifications of etiquette, if
not always ethics. When scientists fail to regulate their activity,
laws and regulations will be made stronger to ensure that they
do, this is a risk that scientists take when they go beyond what
is publicly acceptable.
Other groups are involved in the application
of science in the world. Companies have been responsible for
about 80% of the releases of GMOs in the world (Krattiger &
Rosemarin, 1994). The risks that companies take include investment
into unprofitable products, risks of environmental and/or medical
legal claims, and risks of unwelcome legal restraints. As commercial
seeds and animals are passed on to farmers the farmers will assume
increasing responsibility for sensible farming practice, which
is usually in their long term interests also, e.g. monitoring
of pest resistance to insecticidal proteins. The risks to the
farmers include, crop failure, unprofitable products, damage to
their land or their health, and even possible legal claims against
them.
Each of the groups, or players, involved in
the release of GMOs also has their own set of benefits. Ideally,
all may share the goal of human progress, but they also share
the benefits for their own progress. All three have economic
interests, perhaps scientists less than the other two groups if
the scientists have the luxury of financial support unlinked to
research application. The general public also shares these benefits,
but may have a longer term economic and environmental framework,
and has the benefit of being consumers. Variety or alternatives
can give choice, if such a variety is available, and many people
may also welcome a variety which is lower cost. In fact, when
we consider this factor the public may also have short term economic
sights, when it enters the supermarket. Nevertheless, as discussed
above, there are a number of ethical reasons to give the general
public the major role in deciding what risks and benefits are
acceptable for technologies which do have broad implications,
in fact global implications in the case of genetic engineering.
This means that risk assessment strategies need to be developed
from public concerns as well as the concerns of specialists.
The broad nature of a technology also suggests that social and
ethical impact issues can be included as "risks", and
methods to assess these types of risks would be needed. Genetic
engineering is certainly not an special case, but it has made
people wake up to the fact that many technologies have such broad
potential impacts, and we need to think of risk assessment and
technology assessment in general. In this respect the decision
by the 1995 US government to virtually dismantle the Office of
Technology Assessment is surprising and short-sighted.
However, unless the broader dimensions of
applied science are taught, society will be unable to make balanced
decisions about the use of technology. In all countries in the
International Bioethics Survey there is strong support for teaching
students about the ethical and social issues associated with science
and technology (Macer, 1994a), and such issues are already introduced
into the curriculum to varying degrees in Australia, New Zealand
and Japan, as measured in the International Bioethics Education
Survey. The general attitudes to the teaching of bioethics were
extremely positive. It is interesting that more biology teachers
thought bioethics should be taught in biology classes, while social
teachers thought they should teach it.
There is more inclusion in Australia and New
Zealand teachers than in Japan. There is now some research into
how these issues are being best taught, the most suitable issues,
the suitable classes and the most effective delivery. They are
relevant to both science and social studies classes. The next
stage in the education project is the development of materials
to aid the teaching of these issues, and the responses obtained
were used to make such materials. Teachers are testing some on-line
materials, and developing them for use at appropriate times in
existing courses.
Public education is a special responsibility
of scientists, who have the best knowledge of the technology,
even if they may not know of the impact so much. People who have
high familiarity with such techniques, such as scientists and
high school biology teachers, are also concerned about such technology
(Macer, 1992a). Rather than attempting to dismiss feelings of
concern, society should value and debate these concerns to improve
the bioethical maturity of society. The data suggests that the
public is already informed enough to be trusted in the formation
of policy, and there needs to be inclusion into policy making.
Several countries including Denmark, the Netherlands and the
UK have had public consensus conferences as new methods to involve
the public in decision-making. Public forum, and public notification,
and chance for response, are assumptions of democracy that are
still being excluded in some genetic engineering applications.
In some discussions of the impact of biotechnology
safety and risk are considered separate from bioethical concerns.
However, as shown above, the origin of concern about safety and
impact is the ethical principle of do no harm. People of various
cultures, ages, educational training, occupation and outlook on
life perceive both benefits and risks from developments of science
and technology. People do show the ability to balance benefits
and risks of science and technology. People in the countries
surveyed do not have a simplistic view of science and technology,
and can often perceive both benefits and risks, which calls for
public involvement in the process of risk definition and assessment.
