If earth is considered a " closed system " how does that shape the outcome of environmental problems? how does this relate to local regional environmental problems?

Answer;

We can't bring anything in or out ,

Explanation;

-Nothing enters or leaves a  closed system; for Earth, only sunlight  enters and heat leaves. This means that limited resources cannot be replenished if growing populations consume them at too fast a rate.

-Another consequence is that wastes can accumulate more quickly than they can be disposed of. Environmental problems that have local or regional effects must be dealt with on a different scale—one that takes into account the scope of the given problem. Within a more restricted perspective, smaller areas are not necessarily considered closed systems.
