How Manatees Got Into Hot Water   Leave a comment


Back in the 1970’s, manatees were close to extinction because of ruined habitats and speedboats. Over time power companies started to notice that groups of manatees were congregating around their power plants due to the warm water they produce. This episode of Planet Money discusses the unlikely partnership between environmentalists and power companies to conserve the manatee and how they make that possible. Conservation policies needed to adapt the idea that to save the manatees, the power plants also need to be saved. The warm water keeps the manatees alive but what happens when we move to more renewable energy resources? Pat Rose, a conservationist known as the “manatee man”, joins the show to explain what is going on in the manatee world today and what the future looks like.
