One major way to conserve non renewable resources is to cut down on your use of non-renewable resources by driving less, using less electricity, or buying fewer new things. Another way is to use more renewable energy sources or renewable resources such as wind, solar, or geothermal power. Another way is to seek to increase the efficiency of things that you use which consume power or non-renewables such as lightbulbs, your car, or other appliances.

<h3>How does human population affect wildlife?</h3>
Human population affects wildlife by causing changes or reduction of habitat so that it automatically reduces the population of animals and plants in the wild.
