20 20 PROJECT I SPY

GREENHOUSE EFFECT The result of greenhouse gasses trapping the sun heat and keeping a unit close to the air, crusial and essential for life. Greenhouse gasses are caused by pollution that animals and humans make. For example: HUMANS ANIMALS

GLOBAL WARMING The increase of Earth average surface temperature due to effect greenhouse gasses trapping heat.

VIDEO #1

CAUSES AND CONSECUENCES Green gas emission: Cause: Burning of fossil fuels in cars, factories, and electricity production. Consecuence: Contamination on the city, farms and towns.

PHOTO #2

ELEMENTS Carbon dioxide (CO2) exsist thanks of the fossil fuel burning and deforestataion. Methane (CH4) sourcerice cultivation,cattle i sheep ranching, decay from landfills and minning. Water vapor (h2O) is the most important greenhouse gas!!!

VIDEO #2

PROOF OF GLOBAL WARMING Alaska in 1914 was ice is almost a lake. Colorado river in 2002 Colorado river 2002 is a complete river small ( not a river any more) concluding a desert. Alaska 1914 Alaska in 2004 Colorado river in 2003

PHOTO #3

EFFECTS OF GLOBAL WARMING DUE TO THE UNBALANCE OF GREENHOUSE GASSES Habitats damage and species extinction. Changes in water supplies; contamination of fresh water. More severe storms; huricanes and floods. Droughts, and changes in weather patterns

CAUSE THAT ENCREASE GASSES TO THE ATMOSPHERE Deforetation: cutting down trees and the wood burning. population growth: more people equals more contamination.
