Explanation:

The "Environmental Protection Agency" (EPA) began operating in 1970 as a response to Rachel Carson's publication, Silent Spring. The publication tackled the harmful effects of pesticides to the environment. This alerted the public and such increasing concern was responded by the Congress.
