Across the world, people are celebrating Earth Day in a variety of ways today, from trash clean ups to tree plantings.
Pittsburgh didn’t wait for the actual day, as Earth Day events started last week and will continue in the coming weeks and days.
On Friday ALCOSAN workers gathered at several spots in Allegheny County to pick up litter.
“All the litter we pick up has the tendency to blow into the rivers,” said ALCOSAN spokeswoman Nancy Barylak, “so that litter you see on the side of the road could easily end up in the rivers.”
