You... you realize that if everyone just left their trash everywhere because it wasn't a "pretty forest" then we would be under heaping mounds of trash. Not to mention that eventually the crap would blow and spill over into these "pretty forest"s.

But imagine what would happen if everyone littered one plastic bag. It's important to make sure it's considered socially and morally unacceptable to litter, otherwise everyone would do it. It wouldn't be "one plastic bag" for long....

That's like saying that there's no use crying of every mistake. *In GLaDos voice*

over every mistake* Oops my bad (Fail)

You have failed, no cake for u
