Показать описание
America almost drove the bald eagle to extinction during the 1900s. The main cause was the pesticide DDT and its environmental impact.

Bald eagles are a national symbol of the United States and have a ton of environmental protections today.

But in the early 1900s, the bald eagle was driven to near extinction. Back then, eagles were shot as they were viewed as pests that stole fish. Shootings combined with the environmental impact of DDT on bald eagles caused the near extinction of this species.
