Obtaining nonrenewable resources like oil and coal can cause environmental damage because they are dug up and used up quickly. If there are more people in the world, there will be more need for these resources, which can lead to more pollution and hurt the Earth. Plus, when we use up all the nonrenewable resources, there won't be any left for future generations. So, it's important to find ways to use less of these resources and use more renewable ones like solar and wind power.
