There are about 20,000 animals died from us littering every year.
Lots. Most litterbugs toss their litter out of their cars, so it rests near the road. Most often the animals killed are attracted to that litter and crossing the road to get to it or to return to the wilds after eating and are hit by passing cars as they cross.
I'd say at least one every day, I supose, I live o0n a farm and seen one die right before my eyes once, it was choking with a metal ring around it's throat, I watch at least 4 die, and I've tried to save them, and it would never work
Ten thousand, maybe more,
