The greenhouse effect is caused by the trapping of heat in the earth's atmosphere by greenhouse gases, such as carbon dioxide, methane, and water vapor. Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere, which enhances the greenhouse effect and contributes to global warming. Deforestation can actually exacerbate the greenhouse effect as trees absorb carbon dioxide during photosynthesis. The greenhouse effect is causing an increase in average temperature on the planet, not a decrease. It is also not known to decrease plant growth, as plants rely on carbon dioxide for photosynthesis.
