I have a trash grabber arm. I go to my local park to pick up trash every couple of months. I most recently did it on Earth day; the park was covered in trash again within 3 days. It drives me insane. I will say, some of it is due to open top garbage cans throughout the park, the wind can blow stuff right out of those which reminds me that I need to call the Parks and Rec department. I expect they’ll tell me they have no budget for closed cans.
