Is a renewable resource always renewable?

Answer 1

A renewable resource is like the bank account that you put your paycheque into. Every month you can withdraw money so it is a renewable source of cash and build up a surplus for tough times. This is called living within your means. However if you start withdrawing faster than you put money in it and buy on credit to cover other needs eventually it becomes exhausted and you can't catch up to living within your means again. It is only renewable as long as you handle it responsibly.Similarly a renewable resource (fish, water, forestry products.etc.) can be depleted and usable levels difficult to achieve again.

Answer 2

Ultimately, no. Eventually all energy sources will be depleted when entropy reaches maximum
