Global warming is the increase in the temperature of the earth’s atmosphere and oceans. It is a change that is thought to be irreversibly changing the earths climate. Some people say global warming is a (hoax) and that it is a natural cycle that the earth goes through, but the evidence that supports the theory that humans are the driving force of global warming is just too significant to disregard. Most scientists believe that global warming has been triggered by human expansion of “the greenhouse effect”. This warming takes place when the atmosphere traps heat discharged from earth to space. Certain gases allow the atmosphere to act as a door that only opens inwards, it allows the heat to enter but thwarts it from leaving. The accumulation…show more content…
There are a number of factors that allow scientists to believe that human activity is the source of climate change. Carbon emissions are the main cause of global warming. When human beings burn carbon based fuel like coal and gasoline for energy, the carbon dioxide they release is lighter than the carbon dioxide from other sources. The level of lighter carbon dioxide has increased drastically in the last 40 years. Another cause of global warming is deforestation. It is clearing earth’s forests on a massive scale, often resulting in damage of the quality of the land. Forests are being cut down because humans have become very dependent on wood and paper products, livestock are forced to overgraze on former forest lands. Forests are vital because they remove and store carbon dioxide from the atmosphere, this means deforestation releases a lot of excess carbon dioxide and it reduces the amount of carbon detainment. According to the United Nations ‘Food and Agriculture Organization’, 18 million acres of forest, which is roughly the size of Panama, are lost each year. The overabundance of chemical fertilizers in crop lands is yet another cause of global warming. Towards the end of the 1900s, the use of chemical fertilizers had grown drastically. The increased usage of nitrogen rich fertilizers has negative effects on the heat incarceration of the crop land. Nitrogen oxide has 300 times heat trapping potential per unit of volume. The run-off of the residual fertilizers creates what is referred to as “dead zones” in the oceans. In addition to these side-effects, these fertilizers implanted within the earth cause a perturbation towards human
