The habitat banker

Our planet is in serious trouble. There are a million species of plants and animals in danger of extinction, and the biggest cause is companies destroying their habitats to farm food, mine minerals, and otherwise get the raw materials to turn into the products we all consume.

So, when Mauricio Serna was in college, he realized his family's plot of land in Colombia, called El Globo, presented a unique opportunity. Sure, it had historically been a cattle ranch. But if he could get the money to turn it back into cloud forest, perhaps it could once again be a habitat for the animals who used to live there - animals like the yellow-eared parrot, the tree ocelot, and the spectacled bear (of Paddington fame).

On today's show, Mauricio's quest to make a market for a new-ish financial instrument: the biodiversity credit. We peek under the hood to try to figure out how these credits actually work. Is the hype around them a bunch of hot air? Or could they be a critical tool for saving thousands of species around the world?
