Why Everything They Say About The Amazon, Including That It's The 'Lungs Of The World,' Is Wrong

Commentary from Michael Shellenberger on Forbes.com (Aug. 26):

The increase in fires burning in Brazil set off a storm of international outrage last week. Celebrities, environmentalists, and political leaders blame Brazilian president, Jair Bolsonaro, for destroying the world’s largest rainforest, the Amazon, which they say is the “lungs of the world.”

I was curious to hear what one of the world’s leading Amazon forest experts, Dan Nepstad, had to say about the “lungs” claim.

“It’s bullshit,” he said. “There’s no science behind that. The Amazon produces a lot of oxygen but it uses the same amount of oxygen through respiration so it’s a wash.”

What about The New York Times claim that “If enough rain forest is lost and can’t be restored, the area will become savanna, which doesn’t store as much carbon, meaning a reduction in the planet’s ‘lung capacity’”?

Also not true, said Nepstad, who was a lead author of the most recent Intergovernmental Panel on Climate Change report. “The Amazon produces a lot of oxygen, but so do soy farms and [cattle] pastures.” [read more]

It’s not like the Amazon jungle is the only place on earth that has trees. The Amazon jungle is just another prop for the Left.
