Friday, April 22nd will mark the 41st annual Earth Day, and all divers should get involved to ensure our watery playgrounds stay clean and healthy for years to come. Even if you're not an environmental activist, you should at least get out and have some fun! This page provides links to a bunch of Earth Day activities — both dive-specific and land-based — you might want to check out this year. Some of the activities include underwater clean-ups, festivals, beach cleanups, reef surveys and more.
