The greatest environmentalist of postwar America wasn’t a scientist or a wonk. He didn’t even finish high school.

Brooklyn native Tony Mazzocchi, who passed away in 2002, isn’t a household name — yet. But when a future socialist society on the other side of the climate crisis goes looking for statues to build and parks to name, he will be at the top of the list.

Today, the AFL-CIO lobbies Congress to pass the Keystone XL pipeline while noted NASA climate scientist James Hansen, one of the first to link global warming to fossil fuels, is repeatedly arrested for protesting such projects. And while in 2017, the idea that the interests between wonky environmentalists and jobs-focused trade unionists would diverge seems like common sense, it’s only because the bad guys won.
