Congress’s response to the 1962 publication of rachel carson’s silent spring was to restrict the use of ddt. enact earth day. fund the love canal cleanup. promote the sierra club’s efforts.

The correct answer is "restrict the use of DDT."

In her book Silent Spring, Rachel Carson discusses how pesticides like DDT are dangerous to the environment. Carson's book focuses around important environmental issues of the 50's and 60's and uses statistics from research to support her claims. This eye opening book grabs national attention and results in Congress developing laws to protect the environment.
