Its high time they realized the prob
42、lem.“ The fourth student, Liza Vernum, said she thought the public were mostly on their side, and even if they werent, they soon would be.

Man, however much he may like to. pretend the contrary, is part of nature. Can
46、he escape a pollution that is now so thoroughly distributed throughout our world? We know that even single exposures to these chemicals, ff the amount is large enough, can cause extremely severe poisoning. But this is not the major problem. The sudden illness or death of farmers, farm workers, anti
