"no personal incentive to throw away the trash" is not such a good defence to the dumb tourist's intelligence as you make it seem.

"Leave no trace" is very important (and point taken -- some people don't take it seriously enough and it reflects quite poorly on them), but bears are facing hunger and possibly even starvation if they don't find some food source.

That's less dumb and more egotistical, just because tourist is an asshole doesn't mean they are automatically dumb.

I disagree, if you are an asshole to the degree that you're just throwing trash on the ground, you cannot be that intelligent.

An intelligent asshole still throws trash away properly.
