"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.
