Question

Banning the use of DDT as an agricultural pesticide is based on the evidence in the passage that states A) DDT was no longer effective in controlling malaria. B) DDT was getting too expensive for most people to use. C) DDT use resulted in the decline in some species due to biomagnification. D) DDT pollution resulted in a decline in soil fertility and an increase in plant species.

Answer 1

I believe the answer is C because DDT is a very toxic chemical to all animals, and when it’s sprayed on plants the animals will be bound to eat the toxin-covered plants, and other animals will eat the animal that eats that plant along with the toxins which is known as biomagnification. As a result of this, many species will become very sick and die from the fatal pesticide.
