Everywhere you look these days, things are turning green. In Chiapas, Mexico, indigenous farmers are being paid to protect the last vast stretch of rainforest in Mesoamerica. In the Brazilian Amazon, peasant families are given a monthly “green basket” of basic food staples to allow them to get by without cutting down trees. In Kenya, small farmers who plant climate-hardy trees and protect green zones are promised payment for their part in the fight to reduce global warming.
