Last night at the Cambridge Forum, journalist and author Wen Stephenson gave an eloquent presentation of his new book, WHAT WE’RE FIGHTING FOR NOW IS EACH OTHER: Dispatches from the Front Lines of Climate Justice. He was inspired by the Westborough 8, for whom he served on the backup team, and other activists like Tim DeChristopher. Stephenson stressed the need for quick, radical action and loving dedication and the imperative to protect humanity and especially the poor, who are disproportionately affected by climate change.
