Today is Earth Day and this year, with the worries about climate change, there is so much we must do to help the environment. Now is the perfect time to get your friends, family, neighbors, and coworkers involved in Earth Day projects.

For over 40 years, people have been celebrating Earth Day, a time that we get our hands dirty to help the environment and “work through a combination of education, public policy, and consumer campaigns.” Earth Day began as an American celebration—the first Earth Day occurred on April 22, 1970, with over 20 million American participants—but today over one billion people around the world participate.

Every year, the Earth Day Network (EDN) and other environmental organizations help people come up Earth Day projects.

3 Earth Day Projects

Listed below are just three ideas for you to consider on your Earth Day project.

Plant Trees

The Rainforest Action Network reports that each year 3.5 billion to 7 billion trees are cut down. The Earth Day Network hopes to help rectify this by planting 7.8 billion trees by Earth Day 2020. This Earth Day, call a local tree organization and see if they are planting trees anytime soon. You and your loved ones can likely join them or you can plant a tree in your own yard.

Start or Participate in a Community Garden

The American Community Garden Association estimates that there are 18,000 community gardens throughout the United States and Canada. Community gardens are a great way to bond with your neighbors, get some exercise, and supplement your groceries. They also add more greenery to your environment. For example, you can start gathering interest from your neighbors about starting a community garden. Or if you want to join an established community garden, you can try finding one with this website. It lists all the registered community gardens in your area.

March for Science

Consider joining the Earth Day Network for the March for Science rally and teach-in on the National Mall. It’s held every year. The purpose of the march is to “defend the vital public service role science plays in our communities and our world”. It also aims to “hold our leaders—both in science and in politics—accountable to the highest standards of honesty, fairness, and integrity.” Additionally, Greenpeace, The Nature Conservancy, Endangered Species Coalition, Center for Biological Diversity, National Parks Conservation Association and Audubon will be partnering with EDN for the event.
