Carbon is a basic element of life on Earth. It is the most abundant element, one on which many life systems depend, and a primary source of energy (fossil fuels). Today carbon is in huge turmoil—humans are on their way to creating a global carbon crisis. Eons of stable transformation and retransformation of carbon on Earth are now being destabilized by anthropogenic activities. Large human populations, their habitats, production and consumption processes are leading to a significant overuse of the element carbon. Excessive use of non-renewable, carbon-based fuels has caused excessive emissions of carbon dioxide into the Earth’s atmosphere.
