On April 22, 1970, nearly 20 million Americans attended the first Earth Day celebration, an event designed to raise awareness of important environmental issues such as pollution, waste, ozone depletion, and wildlife extinction. Earth Day is even more relevant today, focusing on issues such as the increasing amount of garbage in landfills and the rising levels of carbon in the atmosphere, with a goal of helping preserve the health of the Earth. New York City venues have planned fun-filled events to observe the holiday.
