Greenhouse effect.

We owe this much interested in?

Clearly, if these are the most important des:
• The melting of glaciers, melting of snow early and severe droughts will cause more water shortages in the western United States.
• Rising sea levels cause coastal flooding on the Eastern seaboard, Florida and other areas like the Gulf of Mexico.

• Forests, farms and cities will face troublesome new pests and more mosquito-borne diseases.
• Disruption of habitats such as coral reefs and alpine meadows could drive many species to extinction of plants and animals.

What causes global warming?

Carbon dioxide and other air pollutants accumulate in the atmosphere forming a layer growing thicker, trapping the sun's heat and causingglobal warming. The main source of contamination by carbon dioxide emissions are power generation plants based on coal, then emit 2.500million tons per year. The second leading cause, are cars emit

about 1.500 million tons of CO2 per year.

How can we reduce pollution?

It's simple: By reducing pollution from vehicles and power plants. We immediately generalize the use of existing technologies to producecleaner cars and power generators more modern. We can start using renewable energy sources like wind, solar and geothermal. And we can manufacture more efficient appliances and conserve energy.
