Scarce water
434 million experience water stress or scarcity, projected 3.1 billion.
Scarce Cropland
500 million live in area were cropland is scarce, projected 950 million.

Affects 2/3 of developing nations.

6. Greenhouse Effect and Global Warming
Greenhouse effect: water vapor and gases in the atmosphere absorb and reflect rays and warm earths surface.
Carbon dioxide (fossil fuels)
Ozone
Methane
Chlorofluorocarbons
Global Warming: increase in the earths average temperature.

8. Destruction of the Ozone Layer
A protective layer in the upper atmosphere that traps ultraviolet (UV) radiation and prevents it from reaching earths surface.
Chemicals that destroy Ozone
Chlorofluorocarbons (CFC’s):
Aerosol
Air conditioners
Halons
Fire extinguishers

9. Destruction of Rain Forest
Hot, wet forested area that contains many species of trees, animals, and plants. Covers 7% of earths land.
The trees remove co2 and produce oxygen.
Half of the worlds plant in animal species live in rain forest.
Destruction rates: 240 square miles every day, equals 6417 acres per hour, 107 acres per minute or 1.78 acres per second.
