privilege leads to more serious problems than not getting somewhere on time. Car emissions produce three types of carbon - Carbon Monoxide (CO) and Carbon Dioxide (CO2) and hydrocarbon (CH4) - which are traumatizing both our health and the environment. By itself‚ carbon isn’t a harmful element‚ but one of its characteristics is easily pairing up with majority the elements in the periodic table. Its ability to bond is infinite; it can create many different substances without any problems. Carbon Monoxide

The Carbon Cycle The element Carbon is the principle block for the organic compounds that make up life. This is because the study of the Carbon Cycle draws upon theories from biology‚ chemistry‚ geology and oceanography in order to understand the movement of carbon throughout the atmosphere‚ hydrosphere‚ and geosphere. Carbon is made up of four electrons that are able to form with each other; this causes the many different forms of carbon. The most popular form of carbon is carbon dioxide; this

ABSTRACT We are in debt to Carbon Dioxide (CO2) and other green house gases for our presence on earth. As they help in stabilizing temperatures to levels sustainable for organic life – by what is known as green house effect. In modern times burning of fossil fuels like coal‚ oil‚ and natural gas combined with fast deforestation has led to unprecedented level of green house gas emission. Here came in to existence the concept of Carbon Emission Trading developed during the Kyoto Protocol in 1997
