Renewable vs. Nonrenewable Are there any items on the renewable list that could become nonrenewable? Are there any items on the renewable list that could become nonrenewable?

Renewable Many renewable resources could become so polluted or overused that they would no longer be valuable. Many renewable resources could become so polluted or overused that they would no longer be valuable.

Human Population Growth The human population exhibits exponential growth. The human population exhibits exponential growth. As more people move around, more natural resourced are needed.
