Earth Day happens every year on April 22. First held in 1970, Earth Day is now one of the largest global holiday celebrations, including one billion people in more than 193 countries. This year’s theme is “Invest in Our Planet,” so here are some simple ways to act on Earth Day—and every day—to protect this glorious planet we call home.

Get outside. When the weather is nice, skip the gym, treadmill and elliptical and get outside. You’ll save energy while burning calories walking, running or bike riding in nature.

Pause on plastic. Drinking water is good for you, but the millions of single-use plastic bottles in our landfills are not good for the environment. Invest in a non-disposable bottle to quench your thirst. You’ll save money and reduce non-degradable waste.

Plant a tree. Trees give off oxygen we need to breathe. They reduce storm water runoff which slows the erosion and pollution of our waterways. Trees also provide food, protection and shelter for many birds and mammals. Contribute to our future by planting one today.

Pick up trash. Every piece of trash you recycle or throw away is one less dangerous item for birds, turtles or whales to swallow. Picking up trash also beautifies our world and reduces the stress put on government agencies to keep up with litter. If you see a piece of trash outside, take a moment to pick it up and throw it away or recycle it.

Finally, the best way to celebrate Earth Day is to get educated and involved in your community. There’s nothing more empowering than action for meaningful change. Invest your passion, energy and enthusiasm to make a positive difference. Learn more at earthday.org.
