2. Section 37.1 Manage Technology
Our natural resources are vital to our survival and way of life.
Conserving energy and water is an important part of protecting our environment. 2

5. Earth’s Natural Resources
The global environment makes up the life support systems of the whole plant.
Some resources are renewable, which means they can replace themselves naturally over time.
Other resources are nonrenewable; they cannot be replaced once they are used.
global environment
The life support systems of the whole planet. 5

6. Earth’s Natural Resources
Fossil fuels, fuels that come from living matter, come from coal, oil, and natural gas.
Conservation is the careful management and protection and natural resources.
fossil fuel
Fuels gained from living matter from a previous geologic time.
conservation
The careful management and protection of natural resources. 6

8. Conserving Energy
Conserving energy helps save money and reduce pollution.
Conserving
energy applies
to heating and
cooling systems,
appliances and
lighting, and
transportation.

9. Conserve Water
Save water by turning it off when you brush your teeth, takes showers instead of baths, and fix leaks.
Use products that are formulated to bread down easily in the environment, that is, biodegradable.
Do not dump hazardous wastes into drains and sewers.
biodegradable
Formulated to break down easily in the environment. 9

10. Section 37.2 Clean Up the Earth
Protecting our environment
involves taking steps to
control air, water, and land
pollution.
You can use a “reduce,
reuse, and recycle”
strategy to minimize
waste. 10

11. Content Vocabulary Academic Vocabulary pollution pollutant
global warming
ozone layer
acid rain
landfill
precycling
recycled-content products
generate
transform

12. How Pollution Occurs
Pollution is the presence of harmful substances in the environment called pollutants.
Most pollution is caused by people, and industrial nations are responsible for most of it.
pollution
The presence of harmful substances in the environment.
pollutants
Harmful substances. 12

13. How Pollution Occurs
Global warming is the gradual increase in the earth’s surface temperature caused by depletion of the ozone layer.
global warming
The gradual increase in the earth’s surface temperature caused by depletion of the earth’s ozone layer.
ozone layer
A layer in the earth’s upper atmosphere that is meant to block out and protect the earth from most of the sun’s harmful ultraviolet rays. 13

14. How Pollution Occurs
Acid rain results from the combination of fossil fuel emission and water in the atmosphere.
acid rain
The environmentally damaging and physically harmful rain that results from the combination of fossil fuel emissions and water in the atmosphere. 14

15. How Pollution Occurs
Water pollution comes from chemicals and waste products making their way into our water sources.
Land pollution comes form the disposal of household and industrial water, usually into landfills.
landfill
An area where waste is dumped and buried. 15

16. Reduce, Reuse, Recycle
Reduce waste by making environmentally responsible choices.
Precycling includes buying products that use less packaging, cutting back on disposable products, and using cloth bags.
precycling
Reducing waste with environmentally responsible consumer choices. 16

17. Reduce, Reuse, Recycle
Reuse any items you can, share items, and buy used goods.
Recycling conserves energy, natural resources, and helps
reduce waste.
Use items that
are made from
materials that may
have landed in
landfills. 17

18. Chapter Summary Section 37.1
Conserve Resources
Everyone must work to solve global environmental problems.
Renewable resources can replace themselves over time, and nonrenewable resources cannot. Active conservation is needed to protect natural resources.

19. Chapter Summary Section 37.1
Conserve Resources
Energy conservation reduces fuel consumption and cuts back on air pollution.
You can conserve energy and water by paying attention to your usage patterns and changing wasteful habits.

20. Chapter Summary Section 37.2
Clean Up the Earth
Pollution of the air, water, and land results mainly from human activities.
Air pollution is linked to global warming, the depletion of the ozone layer, and acid rain.

21. Chapter Summary Section 37.2
Clean Up the Earth
Our supply of fresh water is limited, and so it is important to conserve water.
Land pollution results from the disposal of household and industrial waste.
You can cut back on waste by reducing, reusing, and recycling.
