Answer 1

Oil is the main source of energy, but at the same time the main source of CO2. After undergoes certain chemical transformations, oil is used motor vehicle engines, airplanes and also in energy production stations.Coal is guilty, in the same way as oil, climate change. Because of increased usage, it may soon become the number one enemy of the climate. Burning coal releases large amounts of CO2 into the air. Lignite is even more dangerous than oil. Although it is estimated that coal reserves are sufficient for several hundred years, their uncontrolled use can be a catastrophe for the global climate.Natural gas is considered the most "clean" form of energy fuels and can be employed effectively to produce heat and power. But they emit CO2 in amounts as high as lignite, for each KW / h generated.Tropical forest destruction is responsible for the emission of more than 20% of CO2. Deforestation is particularly dangerous because they can lead to the collapse of an entire ecosystem, such as the Amazon.Methane nitrate and industrial gases are also greenhouse gases. The main sources of methane comes from livestock, agriculture and deforestation. All agriculture is the source for the production of nitrogen. Industrial gases used in refrigerators, air conditioners and some other chemical processes also pollute the air.
