The Activities On Earth Day

Earth Day is celebrated to raise public awareness about the environment and mark the annual anniversary of the first Earth Day.  Climate change is caused by human activities such as burning fossil fuels, which emit heat-trapping carbon dioxide and other greenhouse gases into the atmosphere that raise global temperatures and disrupt weather patterns. The impacts of climate change around the world include extreme weather events such as massive floods and intense wildfires. In 2021, thousands of scientists warned that ignoring climate change will yield "untold suffering" for humanity.

The Reason To Celebrate Earth Day

Earth Day has helped put environmental issues on the national agenda in the U.S. The event also inspired various environmental legislation in the 1970s, including the Clean Water Act (1972) and the Toxic Substances Control Act (1976), according to Columbia University's State of the Planet news website. And the impact of Earth Day has gone far beyond the U.S. For example, the United Nations General Assembly formally recognized April 22 as International Mother Earth Day in 2009, according to the United Nations Environment Programme.
