SunGreenhouse Effect
The greenhouse effect is caused by human activities which produce the greenhouse gases; carbon dioxide, methane, nitrous oxide and fluorocarbons.
Carbon dioxide is the main greenhouse gas and is produced by fossil fuel burning power plants, heating systems, factories, and modes of transportation that burn fossil fuels.
Methane is another greenhouse gas produced by human use of land, including the livestock we use and such agricultural objects as rice fields, wetlands and marshes.
Nitrous oxide is produced by the exhaust of cars, human disposal of waste and human use of nitrogen-based fertilizers.
Fluorocarbons are gases which are emitted when humans use their refrigerators and their air conditioners
Causes
Affects
• Global warming will affect human health in a number of different ways
• The spread of infectious diseases will be affected
• Agriculture will be affected• Extreme weather patterns will be affected• The amount of smog near the ground will be
affected• The supply of freshwater available to humans
will be affected• Coral reefs• The polar ice caps
