Environmental Problems and Solutions

The five major kinds of pollution are gases, noise, garbage, chemicals and

• dirt.

• odors.

• radiation.

• rain.

Using fewer natural resources and reducing wastes can help

• slow human population growth and increase diversity.

• stop illness and create fossil fuels.

• prevent biodiversity and destroy species.

• end habitat destruction and reduce pollution.

• electrical reuse.

Three ways to conserve resources are reusing, recycling, and

• rebuilding.

• reducing.

• renewing.

• repurposing.

Human population growth has been made possible because of

• advances in farming and medicine.
