On this day in history, Earth Day was first observed with the goal of bringing awareness to growing ecological concerns and helping to bring political pressure to bear on environmental issues. An estimated 20 million people attended inaugural events across the U.S. The day was promoted tirelessly by Senator Gaylord Nelson of Wisconsin, who had been attempting to bring his colleagues on board since 1963.
Congress went on to make the 1970s the “Environmental Decade” by establishing the bulk of today’s environmental regulatory authority through the passage of 28 pieces of legislation, including the Endangered Species Act, the Occupational Health and Safety Act, the Safe Drinking Water Act, the Toxic Substances Control Act, and amendments strengthening the National Environmental Policy Act and the Clean Air and Water Acts. In December 1970, Congress authorized the creation of a new federal agency to oversee environmental issues, the U.S. Environmental Protection Agency.
Today, as climate change accelerates, there are many movements to repair ecological devastation, as well as sources for information still associated with Earth Day, such as The Earth Day Network. You can visit their website here.
