"Only humans make waste nature cannot digest." What did the captain mean by this?

• Nature cannot recycle or reuse much of the trash humans produce.

• Nature is great at recycling or reusing most of the trash humans produce.

• Humans are poor at recycling.

• Humans are poor at disposing of trash.

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.
