Happy Earth Day!

Hey everyone, Gambit here, and Happy Earth Day! For the 55th year, the world is using the day to celebrate Mother Nature and the wonderful planet we live on.

Earth Day is a holiday in which us humans  concern for nature. 

Earth Day falls on April 22 every year. This year, it falls on a Tuesday.

The day has been celebrated for 55 years, but it isn't federally recognized, as previously reported by USA TODAY.

The march was coordinated by Denis Hayes, who was a student at the time and is now a board member emeritus for EarthDay.org, according to Davies.

Around one in ten Americans marched that day in 1970 to demand cleaner air and water, said Davies. The march led to the creation of the Environmental Protection Agency, the Clean Air Act, and the Clean Water Act.

"There's never been another event as big as that anywhere in the world," said Davies. "Actually, I think it still remains the biggest civic event of all time."

People who marched on the first Earth Day were "from all kinds of backgrounds, all different walks of life, all ages," said Davies. "Some people are in suits, some people are in jeans."

There are plenty of things people can do, big or small, if they're feeling the holiday spirit and want to connect with Mother Nature.

"The most important thing that you can do is wake up in the morning and do one thing that you've never done before that's good for you. Good for the planet," said Davies.

So go outside, plant a tree, pick up trash, or just water some flowers.

Well this has been Gambit with Back in the Outback. I'm off to plant a tree!
