The first time Earth Day was celebrated was in 1970, giving a voice to an emerging public consciousness about protecting the environment and our planet. The idea to celebrate Mother Earth began in the United States, and in 1990, it became a global movement.
According to earthday.org, the idea for a first Earth Day went like this:
“Senator Gaylord Nelson, a junior senator from Wisconsin, had long been concerned about the deteriorating environment in the United States. Then in January 1969, he and many others witnessed the ravages of a massive oil spill in Santa Barbara, California. Inspired by the student anti-war movement, Senator Nelson wanted to infuse the energy of student anti-war protests with an emerging public consciousness about air and water pollution. Senator Nelson announced the idea for a teach-in on college campuses to the national media, and persuaded Pete McCloskey, a conservation-minded Republican Congressman, to serve as his co-chair. They recruited Denis Hayes, a young activist, to organize the campus teach-ins and they choose April 22, a weekday falling between Spring Break and Final Exams, to maximize the greatest student participation.
“Recognizing its potential to inspire all Americans, Hayes built a national staff of 85 to promote events across the land and the effort soon broadened to include a wide range of organizations, faith groups, and others. They changed the name to Earth Day, which immediately sparked national media attention, and caught on across the country. Earth Day inspired 20 million Americans — at the time, 10% of the total population of the United States — to take to the streets, parks and auditoriums to demonstrate against the impacts of 150 years of industrial development which had left a growing legacy of serious human health impacts. Thousands of colleges and universities organized protests against the deterioration of the environment and there were massive coast-to-coast rallies in cities, towns, and communities.
“Groups that had been fighting individually against oil spills, polluting factories and power plants, raw sewage, toxic dumps, pesticides, freeways, the loss of wilderness and the extinction of wildlife united on Earth Day around these shared common values. Earth Day 1970 achieved a rare political alignment, enlisting support from Republicans and Democrats, rich and poor, urban dwellers and farmers, business and labor leaders. By the end of 1970, the first Earth Day led to the creation of the United States Environmental Protection Agency and the passage of other first of their kind environmental laws, including the National Environmental Education Act, the Occupational Safety and Health Act, and the Clean Air Act. Two years later Congress passed the Clean Water Act. A year after that, Congress passed the Endangered Species Act and soon after the Federal Insecticide, Fungicide, and Rodenticide Act. These laws have protected millions of men, women and children from disease and death and have protected hundreds of species from extinction.”
