I worked with a group of my friends near the beginning of high school for a project involving the environment for a class. We did our research and found out that Heal the Bay, a well known environmental non profit organization was holding a beach clean up day at Venice Beach in California for anyone who wanted to volunteer. There seemed to be about 70-ish people purely as volunteers like us to pick up any trash on the beach that day. It was an amazing and eye opening experience that I'd love to do again.
