What a great example of "be the change you want to see in the world". We've all been there, seeing trash on a beach that we know we should pick up, but there is just so much that it feels futile. That's obviously the wrong way to think about it.
This was such a cool thing to see. One guy, picking up trash, then we joined him, then a few more people until it snowballed into about 20 people cleaning the beach. Since this happened I've always been filling a bag with trash every time I visit the beach.
