In 1969, the United States passed legislation banning the pesticide DDT. It had been discovered that the chemical was harmful to both humans and the environment. For instance, bald eagles ingested DDT through contaminated fish. It made their eggs too thin and not able to hatch. The ban on DDT played an important role in the recovery of the bald eagle. The bald eagle population has since increased dramatically, and in 2007, the bird was removed from the endangered species list.

(Choice D)
