Earth's green house effects is directly related to the carbon cycle.
carbon is known as the building block of life and also a form of stored energy. When fossil fuels such as coal and oil products are burned for energy, carbon dioxide is released . Carbon compounds move in a cycle through plants and animals, the air, ocean and earth.
Carbon that is in the air is the one that contributes to the greenhouse effect. Activities of man especially the burning of fossil fuels for energy is thought to release a lot of carbon dioxide in the air significantly contributing to the greenhouse effect.
