David Attenborough suggests the battle against climate change could start with a “moral change.” Such as, the BBC reports, the one Attenborough grew up with during World War II, when wasting resources was viewed as simply wrong. This shift in attitude might finally get us past that tired excuse that small differences can’t produce large results. After all, he says, “It’s not that we thought we were going to defeat Hitler by eating a lot of gristle.” But they finished their supper anyway.
Of course, charging emitters 14 bucks per ton of carbon dioxide sounds like a pretty sane suggestion, too. Particularly coming from a Harvard economist.
