Thursday, April 22 marks the 40th anniversary of Earth Day and the environmental movement is stronger than ever. April is a great time to enjoy the social nature of Earth Day celebrations, so this week's tips will focus on group activities.
Tip #1: Participate in a Trail Cleanup
Group trail cleanups allow you to meet other environmentalists while enjoying and protecting the outdoors. Many local Earth Day celebrations feature opportunities to restore hiking trails , river banks , and beaches , leaving our natural resources in a cleaner, healthier condition. Find events in your area on Sierra Club Trails or on the White House's Earth Day website on Serve.gov .
