Greenhouse gases are naturally occurring gases that are also produced as a result of human consumption, such as the burning of fossil fuels. They are essential to life in that a gas such as carbon dioxide (Co2) is essential to photosynthesis and the production of oxygen which helps to sustain life. However, the levels of greenhouse gases are far outreaching their natural limits and are having a negative impact on human and animal life.
