Earth Day is observed every year on April 22 to encourage environmental protection. A three-day event from April 20 to April 22, 2021, will be organized globally by #EARTHDAY.ORG which will include 1 billion people in more than 193 countries. Earth Day was established in 1970 as a day of education about #environmentalissues. This will be the 51st Earth Day. Most years, Earth Day events range from river cleanups to removals of invasive plants. Meanwhile, on the occasion of Earth Day 2021, we bring you interesting facts about the planet on which we are surviving.
The theme for Earth Day 2021 is “Together, We Can Restore Our Earth”. In 1962, Senator Gaylord Nelson who was elected as US Senate at that time was determined to convince the federal government that the planet was at risk. In 1969, Nelson, considered one of the leaders of the modern environmental movement, developed the idea for Earth Day. On the first Earth Day on April 22, 1970, rallies were held in Philadelphia, Chicago, Los Angeles, and most other American cities, according to the Environmental Protection Agency.
