Do you think the humans will always destroy the commons (water, land, etc.) that they share? why or why not?

No, i don't believe so.

Humans will only destroy the commons if we exploit them at a higher pace than they can regenerate.

If we massively exploits them simply for profit, there is a high chance that we would destroy them. But, if we take only what we need and put extra conservation efforts for these resources, they would not be destroyed and we can keep obtaining what we need from the commons.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
