For the 55th year, the world is using Earth Day to celebrate Mother Nature and advocate for protecting the wonderful planet we live on. The first Earth Day was celebrated in 1970, when 20 million people attended inaugural events at schools, universities, and other public areas around the country, according to the Library of Congress’s website. The march happened after more disasters caused by climate change and pollution impacted the country.
