Chapter 2: Problem 1

What information made Rachel Carson concerned about chemical pollution?

Short Answer

Expert verified

Rachel Carson was concerned about chemical pollution due to the widespread use of synthetic pesticides, which she found were harmful to various species and could enter the food chain, potentially causing harm to humans as well. Her observations and study on the adverse effects of these chemicals on non-target species, and the potential threats to larger ecosystem and human health, were the major information that drew her attention towards this issue.

Step by step solution

Understanding Rachel Carson's Work

To answer this question, it is important to understand Rachel Carson's work and background. Carson was a marine biologist and she observed the adverse effects of chemical pesticides on the environment first hand. She found out that these chemicals were not only killing pests but also other non-target species including birds and fish.

Identification of the Source

Carson identified the use of synthetic pesticides after World War II as a significant source of the chemical pollution. As a scientist, she conducted extensive research on this topic and came with the detailed harmful impact not only to the species but also that could have potential harmful effects on human health as well.

Unveiling the Effects on Food Chain

In 'Silent Spring', Carson detailed how these pesticides entered the food chain and bio-magnified, meaning they increased in concentration as they moved up the food chain. This process posed a threat to the higher animals on the food chain, including human beings, who would accumulate the highest concentration of these chemicals.
