Exercise 18

Evaluate the following statements:
a. We should not worry much about exposure to toxic chemicals because almost any chemical, at a large enough dosage, can cause some harm.
b. We should not worry much about exposure to toxic chemicals because, through genetic adaptation, we can develop immunities to such chemicals.
c. We should not worry much about exposure to toxic chemicals because we can use genetic engineering to reduce our susceptibility to their effects.
d. We should not worry about exposure to bisphenol A (BPA) because it has not been absolutely proven scientifically that BPA has killed anyone.
