There's a seductive idea, currently being road-tested, for how to stop the world's forests from disappearing. It relies on big food companies.
That's because most forests are being cleared in order to grow crops or graze cattle. And the resulting palm oil, soybeans or beef find their way into foods being sold by a relatively small number of global companies.
So here's the strategy: Get those companies to boycott products from deforested land, and much of the economic incentive to clear more forests will disappear. This should slow down or even stop the loss of forests.
