Man, however much he may like to pretend the contrary, is part of nature. Can he escape a pollution that is now so thoroughly【C3】______throughout our world?
We know that even single【C4】______to these chemicals, if 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 and others exposed to【C5】______quantities of pesticides is very sad and should not occur. For the population as a whole, we must be more concerned with the delayed effects of absorbing small amounts of the pesticides that【C6】______pollute our world.
Responsible public health officials have pointed out that the biological effects of【C7】______are cumulative(累积的)over long periods of time, and that the danger to the individual may depend on the sum of the exposures received throughout his lifetime. For these very reasons the danger is easily【C8】______. It is human nature to shake off what may seem to us a【C9】______of future disaster. "Men are naturally most impressed by diseases which have obvious signs," says a wise physician, Dr Rene Dubos, "yet some of their worst enemies slowly approach them【C10】______".
A)chemicals I)sufficient
