Global Warming is an important ecological issue because it has many negative effects upon our environment. Global Warming, or what has been called the Greenhouse effect, is the process in which the Earth’s temperature starts increasing. It is caused by many things, and the causes are split up into two groups: man-made, or anthropogenic causes, and natural causes.
Natural causes of Global Warming are causes created by nature. First, among the most common and most significant contributors to global warming is deforestation caused by forest fires. Fires can be natural occurrences in many forests as it is nature's way to clear up old growth to encourage new ones. It also helps fertilize sprouting and existing trees and plants. However, while new trees take much time to grow large enough to absorb large quantities of carbon dioxide and produce sufficient oxygen, Global Warming is still in progress and increasing. Second natural causes of global warming by oceans. The ocean is also a significant contributor to global warming as it naturally contains much polluting carbon due to the ecosystems they support because it has its trash like any other nature thing. Moreover ,studies have shown that the top layers of oceans contain more pollution than the Earth's atmosphere and much of that pollution rises in the atmosphere. The third major cause of global warming in nature is contributed by The North and South Poles. It is in those areas where permafrost which contains large amounts of carbon that have frozen over time. Disturbances to these areas cause the permafrost to melt and release the pollutants into the atmosphere. Keep in mind that the carbon held within these lands have been out of the carbon cycle for thousands of years ,so releasing them would cause an imbalance to natural processes. Gases, including carbon dioxide and methane, are suddenly released at volumes nature isn't prepared for.
Human causes of Global Warming probably do the most damage, and there are many human causes. First, power plants. Power plants are a key contributor to the effects of global warming. Power plants that gain their electricity through the burning of fossil fuel (such as coal plants) are especially to blame for this problem. This is largely because once the fossil fuel is burned to create energy, it releases carbon dioxide. Carbon dioxide is one of the leading factors in global warming because it increase it. Cars, along with other form of transportation that uses fuel to operate, are also human causes of global warming. Cars are fingered as a cause of global warming more than other forms of transportation because of their inefficiency compared to mass transit. As fuel is burned in the engine, the bi-product is the same as in power plants: carbon dioxide.
Another major man-made cause of Global Warming is population. More people means more food, and more methods of transportation, right? That means more methane because there will be more burning of fossil fuels, and more agriculture. People always thinking that agriculture is going to be damaged by global warming ,but the truth agriculture will cause livestock and that will lead to manure which bring a lot of methane ending with co2 damages . Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane.
in conclusion, global warming caused by two main causes which impact our environment and planet in bad way. These causes are natural causes and human causes . In my opinion , these are the most dangerous things that have a bad influence on our planet.
