Paragraph 1 - Introduction
The advancement of technology has brought many convenience and benefits into our lives. Gone were the days when the older generations are needed to walk hundreds and hundreds of miles just to reach a destination and feel very tired and exhausted in the end. During this modern age, we can reach the destination in a very short time and without much energy wasted too. But as we become more dependent to technology, we often abuse it. The rate of factories and automobile being built has increased drastically throughout the years. This has lead to a very worrying problem that is seriously affecting our planet lately; this problem is known as Global Warming. Global warming as its name states is a global phenomenon with a number of effects that is happening in the global level. (D’Silva 2007). Global warming is poses a great threat to our personal lives and also to our world. More and more problems that are happening around us are mainly because of global warming. Our earth is not the same place anymore compared to decades ago, it is now slowly dying and this is a very serious issue that all of us should pay attention to.
Paragraph 2 – Causes
Global warming can be caused by many factors, some which may be of natural causes, and some may be of man-made. Natural causes for global warming include the exploding sun spots which cause unbearable heat and the drastic rise in temperature. The change in orbit which the earth takes, the movement to or from the sun is also one of the reasons why global warming has occurred. Lastly, one of the major reasons for naturally caused global warming is because of large volcanic eruptions on the earth, the eruptions release many poisonous and harmful gases which is not healthy for living things and the earth. Other than that, it also destroys plants and living things. Due to lava being hot, the rise in temperature occurs after volcanic eruptions. (Watson 2007). Natural factors affecting global warming is at a small scale, but man-made or human factors affecting the climate are very severe and serious, it contributes most to the sudden change in temperature and the strange and weird things that are happening around our earth. The excessive use of power and energy has been one of the major culprits for global warming. The constant and out-of-control burning of fossil fuels and natural gasses such as petroleum, diesel to power our automobiles and machines, methane and butane for burning and cooking and many other more. However, recent scientific studies show that various human activities release greenhouse gases. Big, advanced and modern cities are developing into industrialization at a very fast pace, therefore, more factories, roads and highways and more vehicles are needed to facilitate production in order for the city to improve. With all these, the rate of gases such as carbon monoxide, carbon dioxide and sulphur dioxide will increase at a very high rate and this eventually causes the rise in temperature.
Paragraph 3 – Causes (Continued)
Other than that, one of the contributing factors includes the change of lands used. In order for a nation to feed its country or the world, it is important for it to produce many agricultural products such as wheat, rice, vegetables and many more. Here, humans usually replace lands such as jungles and forests and turn them into agricultural lands either by burning the forests, cutting them down or by other means for economic activities. They also turn the forests into lands that are capable of natural vegetations with the use of asphalts and concretes. These practices indirectly affect and changes the way the surface of the earth reflects sunlight and also affects how the surface releases heat. It also affects the rate of regional evaporation, runoff and the pattern of rainfall which occurs monthly and yearly. The changes of land causes effect to the global carbon cycle and land changes can also be termed as...
