Earth Day Theme 2022
The theme for Earth Day 2022 is ‘Invest in our Planet’, because as EarthDay.Org says:
Because a green future is a prosperous future.
We need to act (boldly), innovate (broadly), and implement (equitably). It’s going to take all of us. All in. Businesses, governments, and citizens — everyone accounted for, and everyone accountable. A partnership for the planet.
And while there is still time to solve the climate crisis, time to choose BOTH a prosperous and sustainable future, and time to restore nature and build a healthy planet for our children and their children, time is short.

The History of Earth Day
In 1969, American senator Gaylord Nelson was flying over the Santa Barbara oil spill and was so shocked by the scale of it that he decided to create a day to help prevent future cases.
Many point to the first Earth Day, held in 1970, as the beginning of modern environmental activism.
Earth Day is now the world’s largest civic event.
