For decades, Carter has spearheaded Habitat for Humanity, helping to build affordable homes for those in need. And he hasn't just put in money or raised funds, but has actually gone out to construction sites with a hammer in hand.
He's also been active on the world stage, as The Carter Center has acted as an election monitor, ensuring free and fair elections in more than 100 nations since 1989. And since 1986, The Carter Center has led a global campaign to eradicate guinea worm disease, with remarkable success. In 1986, there were 3.5 million guinea worm infections across 21 nations; as of 2019, there were just 54 provisional cases in the world.
Carter's humanitarian work earned him the Nobel Peace Prize in 2002.
