USING NATURAL RESOURCES

• Farmers aren't the only people who depend on natural resources.
• Natural resources that can be replaced are called renewable resources.
• Resources that can't be replaced are called nonrenewable resources.
• Oil,copper,iron,and gold are all examples of nonrenewable resources.

RENEWABLE RESOURCES

• Timber is made from trees that come from the forest.
• People cutting timber affects the environment.
• People plant new trees to replace trees that were cut.

NONRENEWABLE RESOURCES

• Communities that depend on nonrenewable resources don't last very long.
• Bodie was a busy town.
• Bodie is now a ghost town.

USING RESOURCES WISELY

• New cars run partly on gasoline and partly on electricity.
• Windmills use wind to make electricity.
• Many companies are now making cars that use less gasoline.
