1. A greenhouse is a glass building that lets in the sun's warmth and light, however it doesn't let the heat back out.
A greenhouse = une serre
2
Carbon Dioxide from burning other fuels
Methane from rotting garbage and animal waste
Nitrogen oxides from car exhaust and power-plant smokestacks
Chlorofluorocarbons used in air conditioners and refrigerators.
3. The greenhouse effect can lead to global warming, which could cause polar ice and glaciers to melt - raising ocean levels by as much as three feet. Entire islands could melt, forcing many people to move to higher ground.
Additionally, it could cause the weather to be less predictable, with extreme head, cold, drought, more violent droughts and changes in rain patters. This could make some farm areas unable to grow crops.
