Answer: d. To put an end to widespread pesticide use by illustrating the damage it does to the environment.
Explanation:
In "The Obligation to Endure", Rachel Carson - the author - talks about how dangerous and harmful insecticides are to the environment as well as to humans.
She talks about how pesticides settle into the soil and then go into water systems which humans and other organisms rely on. Once we take this water, the chemicals end up in our bodies and do harm to them.
Even though she is not against pesticides being stopped completely, it would be beneficial to the world if the widespread use of pesticide was stopped.
