You probably know about the trolley problem, where someone is forced to make a decision between inaction that kills five people, or making an effort that kills only one. In this episode of The Only Thing That Lasts, host Sarah Mock looks at this quandary from an agricultural lens. As in, when do we let nature simply take its course, or when do we take action to minimize harm — even when there can be other, peripheral harms? It's an episode that explores differing views on conservation, and how we manage agriculture in America.
