$\bf{\underline{\underline{answer:}}}$

Earth Day 2020: The theme for Earth Day 2020 is climate action. The Earth day is observed on 22 April every year. Earth Day was founded by American senator Gaylord Nelson for environmental education. This day commenced on April 22, 1970, and in 2020 we are observing 50 years of its inception.

Answer 2

Answer:

The first Earth Day in 1970 mobilized millions of Americans for the protection of the planet. On April 22, 1970, 20 million Americans — 10% of the U.S. population at the time — took to the streets, college campuses and hundreds of cities to protest environmental ignorance and demand a new way forward for our planet. The first Earth Day is credited with launching the modern environmental movement and is now recognized as the planet’s largest civic event.

Earth Day led to passage of landmark environmental laws in the United States, including the Clean Air, Clean Water and Endangered Species Acts. Many countries soon adopted similar laws, and in 2016, the United Nations chose Earth Day as the day to sign the Paris Climate Agreement into force.
