Jimmy Carter

Jimmy Carter was born and raised on a farm in Plains, Ga. and grew up with an appreciation for nature and the need to protect it. As the 39th President of the United States, he accomplished a great deal for the environment, including the expansion of the national parks system, the establishment of a national energy policy, and the creation of the Department of Energy. He put solar panels on the roof of the White House and encouraged Americans to put on a sweater in the winter instead of turning up the heat. In decades since his presidency, Carter has built a reputation as a humanitarian, a champion for social justice, and a peace-keeping advocate.
