Which statement best reflects the reality of human recycling and trash disposal.

• Recycling and proper trash disposal are not my responsibility. We have sanitation workers.

• Recycling and trash disposal are way too expensive. Polluting nature is just a sad reality we can't really do anything about.

• If humans put their minds to it, we could solve most of our recycling and trash disposal problems. Maybe not all, but anything is better than doing nothing.

• There really is no point in trying to recycle or dispose of trash properly. There is no way to solve the problem or make it better.
