Earth Day 2021 is Thursday, April 22nd. My local county is having a virtual celebration that day instead of activities at a local park. I suggest you check your local government’s website or earthday.org’s online celebration. 3 Days April 20th to April 22nd. There is a great post there, 52 Ways To Restore Our Earth. First on the list is plogging – picking up litter while jogging. See the article for lots of ideas.
