In his youth, Carpenter spent his summers on his grandfather's farm in Missouri. During this time he and his relatives enjoyed fishing, hunting and camping. “Hiking, camping, fishing, and hunting all come together in ecology,” he says. “I was really excited when I discovered there was a way to get paid for being a scientist outdoors.”

impacted the ecosystem of Lake
Mendota. These investigations led Carpenter to devise strategies to manage the phosphorus cycle. By the mid-1990s he began to study the economics of eutrophication, in which he compared the benefits factories and farms receive by causing eutrophication to the benefits of keeping a lake clean and clear with the goal of maximizing the benefits on both sides. From 1999 to 2009 Carpenter led the
