Sorry, but this is a purely political piece of garbage. It's full of claims unsupported by their data. For example, all their data shows population growth is a central issue but they focus on "affluence" and then they cherry-pick the (already affluent, saturated in consumption) first world to attack and suggest improvements for when the elephant in the room is the third world with its not exactly "affluent" but at least no longer starving population that is beginning to do what they suggest we stop doing. Then the typical radical left / eco-socialist "solutions" appear out of nowhere. It's disappointing that such political pieces are now in mainstream science publications (presumably because it's en vogue to kneel to the radical left...).
