I feel like if Greenpeace DID try and say what kind of changes they propose, it’d be wading in to the middle of a bunch of engineering and cryptographer arguments.

The unstated part, is ethereum is the socially responsible cryptocurrency and bitcoin is the bad one.

Personally, I am worried about climate change, and while bitcoin isn’t the biggest contributor, there are lower impact solutions for consensus. But we should also encourage the purchase and use of e-bikes and raise fewer cows. And fly less, but I flew half way around the world for Nostrica because I felt it was important.
