HOW TO CELEBRATE EARTH DAY
Plant trees. As the date also roughly coincides with U.S. Arbor Day, over time Earth Day has taken on the role of tree-planting. Planting trees helps to reduce greenhouse gas emissions, cleans pollution, secures soil in place to prevent erosion, and provides homes for a lot of biodiversity.
Learn more about the environment. Earth Day is a good time to make a commitment to learning more about the environment and how you can help to protect it. Borrow some library books and read up on an issue such as pollution, endangered species, water shortages, recycling, and climate change. Or, learn about a region you've never considered before, like the Arctic, the deserts, or the rainforests. Think about the issues that concern you the most and if you haven't done so already, join a local group that undertakes activities to help protect the environment in your area.
Sing or listen to "Earth" songs. There are many Earth Day song lyrics available on the Internet. Many follow well-known tunes. These make a fantastic classroom activity and help younger children to become interested in environmental topics. For listening, even iTunes has songs about the Earth for downloading: try searching for words such as "planet", "Earth", "endangered", "pollution" etc.
Ride your bike. Use your bicycle or other forms of human powered transportation to commute to work or school and to run errands.
