The carbon cycle is important because all living things are made of carbon in one way or another. The carbon cycle is how carbon is exchanged throughout the earth: between the atmosphere, oceans, ecosystem and geosphere. If the carbon cycle fails, then life begins to break down, causing life to end.
Carbon in the form of CO2 is present in the atmosphere in a very small amount, about 0.04 percent, but it has a big impact on sustainable life on the planet. The CO2 traps radiation in the atmosphere and acts like a warm blanket around the planet, trapping heat in and keeping the surface from freezing.
