Richard Hammond's Jungle Quest is a documentary where he visits the Amazon rainforest and takes photographs. He doesn't really know what he's doing. There's other people there to make things work out OK, he doesn't have to be responsible or competent, he just has to be charismatic and popular. So it's pretty silly.
He says he wants to inspire people to save the rainforest and that something like 20% of it has been destroyed over the last 30 years. (I forget the exact numbers.) I recommend the South Park episode about the rainforest.
What the documentary doesn't say a word about is why the rainforest is being destroyed. What's the upside of destroying the rainforest? What's the downside of preserving it?
People destroy the rainforest on purpose. And it's not because it simply never occurred to them to save it...
People destroy the rainforest because they want land to live on and farm on. They want to be less god damn poor. They want their lives to suck less. They clear areas of forest to make space for humanity and to improve their lives. "Save the rainforest" means making human lives worse.
There is, of course, a way to save the rainforest without screwing anyone over. But it's not what environmentalists have in mind. The win/win solution goes like this: dramatically reduce building regulations in the U.S. (so there can be way more homes), make the U.S. dramatically more capitalist (so there can be way more jobs), dramatically reduce welfare in the U.S. (so immigrants won't be a drain on the current American taxpayers), and then, after doing all of those, let in immigrants who want a better life and are willing to assimilate. A lot of people would rather assimilate to be Americans than work hard to clear the rainforest to make their lives slightly less miserable. Low paying American jobs pay way more (are way more economically productive) than lots of the reasons people clear the rainforest.
There's no need for there to be a shortage of productive jobs in America. That's caused by destructive government actions.
