The diagram illustrates the cycle depicting transition of CO2 in the Earth atmosphere, generated by various sources.
Overall, the carbon dioxide is constantly produces by different components, from animals and plants to factories, and thus never breaking a cycle or carbon dioxide in the atmosphere of the planet.
According to the data presented in a diagram, the major sources of CO2 are the vehicle exhausts fumes and the factory emissions, which not only go up in the air, but also contaminate the water in rivers or seas, as the water plays the role of an absorber in this case. After the water being contaminated, the carbon dioxide goes into the underground levels and accumulates there.
In addition, it is clearly seen that not only do the human-made activities produce green house gas, but only the natural processes, such as the plant or animal respiration and decomposition of dead organisms in addition to waste products. Moreover, the process called the photosynthesis is started by the sunlight, which activates plants’ ability to ‘breath’. Subsequently, trees and bushes exhaust the CO2 into the atmosphere, which is in turn returned back to Earth by precipitations .
