Environmentalist Bill McKibben is the head of the anti-carbon group 350.org as well as a “notable member” of the “Plastic Pollution Coalition,” which seeks to make all cities “plastic free.”

McKibben has also said this:

“Some fights, like global warming, are necessarily hard. And some fights are no-brainers: let’s stop using plastic stuff we don’t need.”

Unless there’s no other way to get your groceries home from the store, apparently.
