More than three million gallons of oil spewed, killing more than 10,000 seabirds, dolphins, seals, and sea lions. As a reaction to this disaster, activists were mobilized to create environmental regulation, environmental education, and Earth Day. Among the proponents of Earth Day were the people in the front lines of fighting this disaster, Selma Rubin, Marc McGinnes, and Bud Bottoms, founder of Get Oil Out.
