SINCE 1970: Earth Day has been celebrated since 1970. It was first observed in the United States when people took to the streets to protest against the 1969 Santa Barbara oil spill, which killed thousands of sea birds, dolphins, seals, and sea lions.
Earth Day celebrations have played an important role in raising awareness around environmental issues ever since. According to earthday.org, the world’s largest recruiter of the environmental movement, the Earth Day mission is to “diversify, educate and activate the environmental movement worldwide”. The landmark Paris Agreement was signed on Earth Day in 2016.
