With which of the following conclusions do you most tend to agree and why? (a) It is alarming that many synthetic chemicals are detected. Our health, our children’s health, and wildlife are likely affected. Let’s find the sources of the chemicals and stop further emissions. (b) We cannot worry about every low-level contaminant. We cannot reduce emissions to zero and it would be prohibitively expensive to even reduce them to near zero. And, quite often a synthetic chemical also occurs in nature as a natural chemical. Animals and plants have evolved protective means over eons of dealing with natural poisons, and most probably can manage the chemicals in this lake too. Taking a chemical off the market could pose other problems – the chemical that replaces it in an industrial process may also pose problems that are now unknown. Let’s devote our limited resources to higher-risk problems
