Earth Day and March for Science - April 22

Earth floats in space with a burning candle wick on top.

Earth Day was founded by United States Senator Gaylord Nelson as an environmental teach-in, first held on April 22, 1970. Activities for Earth Day, and often for the whole week, focus on the environmental issues that the world faces. These issues include extreme weather, rising sea levels, and altered ecosystems due to increased levels of CO2 in Earth's atmosphere.

In conjunction with Earth Day, the March for Science is conducted on April 22, celebrating science and the role it plays in everyday lives. Scientists estimated that 1.07 million people participated in rallies and marches for the first March for Science in 2016.

According to the Earth Day Network, "People march, sign petitions, meet with their elected officials, plant trees, clean up their towns and roads. Corporations and governments use it to make pledges and announce sustainability measures."

One of the simplest and most effective ways to help the environment is to plant a tree. Trees that consume the most carbon dioxide and poisonous gases are pines, oaks, Douglas fir, bald cypress, and black walnut.
