Natural Resources
Nonrenewable resources are resources that nature cannot replace after they are used up, and so they may completely disappear.
Minerals, soil, and fossil fuels are nonrenewable resources.
A fossil fuel, such as coal, natural gas, or oil, is an energy source formed deep inside Earth from the remains of organisms that lived long ago.
Fossil fuels are used to power cars and trucks and they are also used to generate electricity.

Resources on the Move
Most natural resources travel long distances between the places where they occur and the places where they are needed.
For example, the United States uses more oil than it produces, so it must import oil.
An import is something brought into a country to be sold or traded.
An export is something sent out of a country to be sold or traded.
Tanker ships and pipelines move oil to places where it is needed.

The use of natural resources can cause pollution, or the contamination of air, water, or soil by materials that are harmful to living things.
Air, water, and soil are some of the most important natural resources.
Most air pollution comes from fossil fuels burned in cars, trucks, factories, and energy stations. Air pollution can be unhealthy to people, plants, and animals.
