Greenhouse Gases


Greenhouse gases are considered as one of the main causes of the global warming and they can be observed in our environment by increase earth's temperature. The majority of these gases, such as carbon dioxide, methane, nitrous oxide, ozon, water vapor and chlorofluorocarbons come from both natural and artificial origins, but the most of them come from artificial way (human activities). One clear advantage of greenhouse gases is that they play a direct role in keeping our planet habitable. These gases allow direct sunlight to reach the Earth's surface especially the increasing of carbon dioxide in air, which heats up the environment and lead to global warming phenomenon.
