In a surprise move, the Japanese Environmental Agency is preparing a bill aimed at protecting endangered species, nationally and internationally. It is tentatively called the "Preservation of endangered species of wild flora and fauna bill"; Japan Times (23 Feb 1991), 22. Japan has a very poor record in the international trade of endangered species, and this may cover the current loopholes. It may be the result of international pressure, that they have decided to attempt to enact this bill by April.
A further issue of concern for the Japanese is the calls by Sweden and other countries to limit the number of tuna caught. Japan uses 60% of the world's tuna catch, so they are especially concerned. The world stocks of tuna have been said to have fallen by 90% according to Alburon, the US based group. There is a need for managed fishing.

On applications of biotechnology research that may be useful to developing countries see Science 255: 919; Biotechnology 10: 250.
Agricultural systems are designed to exploit the energy conversion from light, to biomass, to provide food. It appears that agricultural systems may be able to convert energy between different levels of the food chain more efficiently than natural ecosystems, according to a study M. Oesterheld et al., "Effect of animal husbandry on herbivore-carrying capacity at a regional scale", Nature 356: 234-6. They looked at South American agricultural ecosystems and found that the biomass of herbivores that were supported was about an order of magnitude more than in natural ecosystems.

A recent World Watch Report released on the 25 April on Environmental Change and destruction has warned that urgent action is required to reduce carbon dioxide emissions to reduce the increase in the greenhouse effect, and that long term conservation efforts are impossible without such changes. The main focus of Life Support: Conserving Biological Diversity was on biodiversity. Many examples of extinctions are cited, and calls made for better stewardship. Comments on where to find biodiversity are in Science 255: 940, 976-9. We need to save both tropical drylands, which are often neglected, and forests.
Genetic analysis, and DNA fingerprinting is being used to determine the relationship between different populations of organisms, e.g. MJA 156: 27-30.
A good example of succesful switching from the use of chemical pesticides in agriculture is the case of rice farming in Indonesia, summarised in Science 256: 1272-3. They use some biological control methods, and integrated pest management, and the rice yiled has increased 10% since 1986 when many chemical pesticides were banned, and this has also avoided much pollution of drinking water.

The view of the US refusal to sign the biodiversity treaty from the perspective of the biotech business, and the support of the Association of Biotechnology Companies is in GEN 12(10), 1, 12. Their major objection is to the patent protection clauses, and to giving countries legal rights to their national flora and fauna. However, it is likely that an international law will be developed to extend national patrimony, something which may move some of the ownership of technology back to developing countries. Ideally we could hope for all humanity to share the benefits, but while industry continues to seek ownership of a disproportionate total of the world's genetic resources, some counter protection should be developed.
