Calling him just a "co-founder of Greenpeace" leaves out some context.

Patrick Albert Moore (born June 15, 1947) is a Canadian industry consultant, former activist, an early member and past president of Greenpeace Canada. Since leaving Greenpeace in 1986,[2] Moore has criticized the environmental movement for what he sees as scare tactics and disinformation, saying that the environmental movement "abandoned science and logic in favor of emotion and sensationalism".[3] Greenpeace has criticized Moore, calling him "a paid spokesman for the nuclear industry, the logging industry, and genetic engineering industry"[4] who "exploits long-gone ties with Greenpeace to sell himself as a speaker and pro-corporate spokesperson".[5]
