Greenpeace is turning 40 tomorrow, but from its childish, immature antics you would never be able to tell. After four decades, this fundraising, campaign machine has become known for its “eye-catching” and “dangerous stunts.” Even organizations and newspapers within Greenpeace’s own environmental community know the group as “an angry teenager.” News flash, Greenpeace: It’s been 40 years, some might say it’s time for you to grow up.

As this Guardian article points out, “While Greenpeace is likely to be found outside a corporate headquarters protesting, its counterparts in WWF might be inside meeting the chief executive.”

Perhaps sitting at the big kids table is all part of growing up.
