I’ve spent a lot of time with indigenous peoples in remote places. So when I argue that the best way – or at least the cheapest way – to stop climate change is to grant land rights to indigenous communities, you might suspect I’m not coming from an entirely objective viewpoint. You’ve probably also heard various industry spokespeople saying the best and cheapest way to stop climate change is through windfarms, solar panels, electric cars and cavity wall insulation. But while I may be biased, and may even have “gone native” now and then, I’m not trying to sell you anything.
