美国科学家正拟在基因农作物的农田中开辟“害虫遗种保护区”。害虫是应被消灭的，“害虫遗种保护区”的出现似乎是件荒唐的事。但这恰恰是自然界给人类出的难题。由于基因农作物不断地产生单一的Ｂｔ．毒素，导致害虫加强了对农药的抵抗能力。对此专家报告建议，在基因农... American scientists are planning to open “pest conservation areas” in the fields of genetically modified crops. Pests are supposed to be eliminated, and the emergence of a “pest reserve” seems absurd. But this is exactly the problem that nature has given to mankind. Genes produce a single Bt continuously because of their genesis. Toxins cause pests to strengthen their resistance to pesticides. Experts report on this proposal, in the gene ...
