Earth Day -- April 22 -- each year marks the anniversary of the birth of the modern environmental movement in 1970.
History and Introduction
Earth Day has come a long way from the first events in 1970, which were based around demonstrations that called for responsible sustainability —and which resulted in the creation of the EPA (Environmental Protection Agency) and legislation protecting water, air, and endangered species.
Earth Day HistoryAnd in the years that followed, the holiday became synonymous with planting trees at the local park, picking up litter from the nearby playground, and with junior-high poster competitions—until 1990, when a massive marketing push inspired 200 million people in 141 countries to participate by addressing recycling as a major issue. Nine years ago, the millennial Earth Day included countless millions in 184 countries.
Earth Day: The EventBy now, Earth Day has cemented its status as a major event—which is good, because we have problems that go deeper than picking up litter or remembering to recycle. The climate hasn't improved in the 39 years since Senator Gaylord Nelson imposed the first celebration; now, the struggle to maintain forests, protect biodiversity, keep oceans and rivers clean, slow global warming, and prevent habitat destruction is more intense than ever.
