Go plant a tree or something. The squirrels in my yard have taken care of their obligation to do that many a time. I have junk trees galore coming out of my old flowerpots.
“Earth Day Every Day” was the 1970s slogan. I used to have bumper stickers to that effect, but since I didn’t have a car (I wasn’t even 10 yet), I put them on the inside of my closet door with my Micky Dolenz posters.
