The use of chemicals in almost all areas of life has become a commonplace phenomenon. There is growing evidence, however, that chemicals in the environment, including pesticides, may contribute to Some illnesses. While studies are still being conducted, preliminary conclusions point to the verdict that such chemicals are indeed negatively impacting those humans to whom they are exposed. Children are especially vulnerable to toxic substances. Pound for pound, they eat, drink and breathe more than adults, all of which exposes them more heavily to those chemicals to which most individuals encounter on a daily basis. Furthermore, their bodies are still in developing stages, exacerbating the negative effects of those chemicals which negatively impact them. Of 50 types of pesticides commonly used in American schools, a study conducted by the National Coalition Against the Misuse of Pesticides found that many caused negative reactions in laboratory animals. Such negative effects included kidney and liver damage, cancer,: and neurological and reproductive problems. These implications of these findings are far-reaching. Given the variety of harmful effects attributed to those pesticides tested, one must pause and consider whether it is wise to continue their use in the nation's schools, where children will be constantly exposed to them. Activists have lobbied for the elimination of such use with a degree of success, and recent findings, if supported by further analysis and confirmation, may help further the cause. A long term solution or alternative, however, remains elusive. In the short run, however, there may be some measures that can be taken to mitigate the harmful effects of dangerous pesticides. The American Medical Association's Council on Scientific Affairs concluded in a 1997 report that given the 'particular uncertainty ... regarding the long-term health effects of low-dose pesticide exposures,' it is 'prudent' for adults and children to limit their exposure and to 'consider the use of the least toxic chemical pesticides or non-chemical alternatives'. The citing of dangerous effects of pesticides on laboratory animals in paragraph 3 is used to suggest that ______.
A.
scientists are also concerned with the effects of pesticides on animals
B.
cancer is the worst effect of the pesticides
C.
most or all of the dangerous effects of pesticides are now known
D.
the chemicals may also cause these effects in humans
