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.

The increase in the amount of persistent chemicals within an organism over time

• Biomagnefication

• 10% Rule

• Energy Pyramid

• Bioaccumulation
