What is Earth Day?
Earth Day is a celebration of our environment held each year on April 22. The first Earth Day was held on April 22, 1970.
Each Earth Day, environmentalists and citizens and kids from around the world participate in events to raise awareness about environmental issues like climate change, pollution, and biodiversity loss. It is a day to reflect, celebrate Earth, and take action to create a better, more sustainable world.
