In nature, there are two types of resources. And those resources are renewable resources and nonrenewable resources.
So, some examples of renewable resources are solar, wind, tidal, and geothermal.

We call these renewable resources because once you use some of it, you’re never going to use it up. In other words, you’re never going to run out of wind. It’s going to continually be there. So those are renewable resources.
Some examples of nonrenewable resources are coal, oil, natural gas, as well as other fossil fuels. Another one is minerals. So these are all nonrenewable resources. Now some of these would form again by the natural processes of the earth, but it would take a really long time.
And so, they don’t renew themselves on the timescale that works for human society. Once they’re used up, we can consider them gone. So these are nonrenewable resources.
Now there are some resources that are generally renewable; but if not used in the right way, they can be nonrenewable. So I’ll kind of write them in between the two sections. So they are timber, wild fish stock, and aquatic food resources.
So all these are renewable because trees continually plant other trees, and there’s going to be more fish, and food grows again. But if someone were to go in and use all the timber for lumber purposes from the forest, and there are no trees left, then there would be no trees there to have more seeds for other trees.
And so then you would have a problem, and no more trees would come up there.
And so these are renewable resources; but if someone doesn’t manage them well, then they can become nonrenewable resources.
