Act 3 is about alternative ecology strands, with the main story being Greenpeace’s campaign to save the whales. We begin with going back to the land, building ecological alternatives and exploring renewable energy. Greenpeace starts by protesting nuclear bombs. But it is putting themselves in front of harpoons to stop whaling that launches Greenpeace on the wildest ride of any environmental group. Soon they are fighting on every front all over the world. Paul Watson, thrown out of Greenpeace for tossing a sealer’s club in the water, is reborn as Sea Shepherd and takes on whalers. Radicals and mainstream come together for a moratorium on whaling, one of environmentalism’s greatest victories, yet a battle that must be fought again and again.
