According to a quote from the Nobel Prize winner, Al Gore, “The entire North Polar ice cap is disappearing before our very eyes. It’s been the size of the continental United States for the last 3 million years and now 40 percent is gone and the rest of it is going.”
Along with the gradual disappearance of the two polar regions of the world, global warming creates a lot of other complications for the people living on this planet. Global warming refers to the increase of the Earth’s average surface temperature. The two principal causes of global warming are some human activities as well as natural processes that occur in this planet which lead to a series of interlinked short term and long term problems.
Global Warming is Caused by Humans
First of all, I believe that the most influential cause of global warming is man-made such as deforestation, using CFC releasing products and burning fossil fuels. This is because the rapidly growing population of this planet is participating in these activities in greater numbers. People are cutting down trees in order to produce numerous industries, resources and dwellings that are required for people to survive. As a result to this, more carbon dioxide remains trapped inside the atmosphere leading to global warming. For example, the National Geographic magazine had published in one of its environmental articles that approximately twenty percent of the Amazon rainforest has been deforested over the past forty years. People are also using common household products like aerosols, old air conditioners and old refrigerators. These products release CFC into the environment which brings about global warming. For instance, CFCs are involved with the decomposition reactions that occur in the atmosphere causing the depletion of the ozone layer. Moreover, human beings require energy in order to survive. The majority of the inhabitants of the world burn non-renewable fossil fuels in order to create energy. Burning fossil fuels releases large amounts of greenhouse gases into the surroundings which trigger global warming. To illustrate, people burn petrol when driving their cars. To sum up, global warming is significantly instigated by some man-made causes which are deforestation, CFC releasing products and the burning of fossil fuels.
Global Warming is Caused by Nature
Furthermore, there are some naturally occurring processes that contribute to global warming such as permafrost, the release of water vapor and the increase of solar activity. First and foremost, permafrost refers to the solid, frozen surface that contains carbon dioxide and methane sealed beneath it. This permafrost has been observed by environmental scientists to emitting the sealed greenhouse gases that cause global warming. For instance, the tundra in Antarctica releases methane and carbon dioxide at a certain temperature range. In addition to this, an increase in water vapor causes more heat to be trapped into the atmosphere. More heat retained in the environment produces global warming. The recent statistics by NASA display that water vapor contains near about two-thirds of the heat trapped by greenhouses gases. Similarly, the increase in solar activity causes the globe to warm up contributing to global warming. This is because an increase in solar activity also increases the levels of solar radiation on Earth. In this case, NASA proclaimed that solar radiation has increased by about four percent over the last 50 years. Hence, some natural causes contributing to global warming are permafrost, the release of water vapor and the increase of solar activity.
How Global Warming Affects Us
The impacts of the man-made causes and the natural causes that lead to global warming are the increase in greenhouse gases, melting of the polar ice caps and increase in the global temperature. First, it can be clearly seen that greenhouse gases are released by both the man-made as well as the natural causes of global warming. The sun projects shortwave radiation to the Earth and after reflecting off the surface, longwave radiation attempts to leave. The large accumulation of greenhouse gases in the atmosphere keeps a larger amount of longwave radiation trapped inside Earth causing the globe to become warmer. For instance, a large amount of carbon dioxide accumulates in the atmosphere due to deforestation and burning of the fossil fuels. Consequently, there is an increase in the global temperature. Increase in the average temperatures can disrupt the way the ecosystem functions causing major changes in plant and animal life. These changes can affect the growth of plants, crops and livestock reducing the worldwide supplies of food. Along with that, the polar ice caps are also melting because of global warming. The rise in global temperatures and the depletion of the ozone layers are causing the polar ice caps to melt. The melting of the polar ice caps lead to an increase in the global sea levels which can result to distressful calamities like floods. Therefore, some of the most evident effects of global warming are the increase in greenhouse gases, melting of the polar ice caps and the increase in global temperature.
To summarize, the combination of man-made and natural causes of global warming increase the concentration of greenhouse gases, melt the polar ice caps and raise the average global temperature. Although it is almost impossible to prevent the natural causes of global warming from taking place, it is very much possible to prevent the human actions that bring about global warming. The foremost step to preventing the man-made causes of global warming is to raise awareness about this issue among the population. Next, a policy needs to be adopted where every time a tree is cut down, 10 more trees should be planted in order to reduce the effects of deforestation. After that, CFC releasing products need to be avoided completely. People should be introduced to newly innovated products such as CFC safe aerosols, refrigerators and air conditioners. Finally, cleaner sources of energy need to be used instead of burning fossil fuels to create energy. For example, solar power and hydroelectricity are some familiar clean energy sources. I strongly feel that if the entire population on this planet works unitedly to prevent the man-made causes of global warming, its effects will be reduced radically.

Sooner or later, we will have to recognise that the Earth has rights, too, to live without pollution. What mankind must know is that human beings cannot live without Mother Earth, but the planet can live without humans.
