“Pollution has caused many kinds of effects to the environment that the different forms of pollutions are harder to be controlled and sadly, they have become more serious throughout the years. Apparently, other than natural disaster it is evident that the major cause of pollution is the irresponsible act of human being. Global warming has become a hot topic nowadays and we must take up the responsibility to resolve this problem. Global warming can be defined as the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels”.

The image of the factory exhausting the gases that creates greenhouse effect. Fig 1: Referring to the above picture, it is clearly proven that the gases from factory has polluted the air , creating an increased in greenhouse effect-  heat-trapping, primarily carbon dioxide, methane, and nitrous oxide. This has also destroyed the atmosphere since most of the gases trap in the air. This is one of the effects of global warming as the temperature rise the warmth would cause the atmosphere to become thinner and thinner. As a conclusion, we have to solve this problem before we lose everything as a consequence of what we have done to Mother nature.

Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.

2.1 CAUSES 1: The Greenhouse Effect
One of the main causes of Global Warming is the Green house effect. When the emission of infra-red radiation in the atmosphere warms a planet's surface, it is known as the Green House Effect. The Greenhouse effect is a natural phenomena occurring on planet Earth. There are natural as well as human-made causes of the greenhouse effect. Industries are also one of the major cause of the Greenhouse Effect because of burning of fossil fuels, oil, coal, and gas and releases those gases into the air. The natural causes of the Green house effect are the emissions of gases like nitrous oxide, carbon-dioxide, methane, ozone and water vapour.  The greenhouse effect is actually beneficial to the Earth. It is only when human-made processes increase its speed that the problems occur. One main problem is the oft repeated 'Global Warming'. Population growth also is a indirect contributor and one of the causes of the Greenhouse effect. the increase in population, the needs and wants of the people increase. Therefore, this increases the manufacturing processes as well as the industry processes. This results in the increase of the release of industrial gases which catalyst the green house effect. The increase in population also results in the increase of agricultural processes. Most man-made machines, like the automobile also contribute to the green house effect. (D’Silva R.)

Fig 3: The Greenhouse Effect. A heat-trapping blanket of greenhouse gases — primarily  carbon dioxide, methane, and nitrous oxide — in the atmosphere can cause potentially significant  changes in the timing and length of the seasons, temperature, and the amount and frequency of  precipitation. ( Washington State Department of Ecology)

Fig 2: From which sectors do the major greenhouse gas emissions come from? The lower part of the picture shows the sources individually for the gases carbon dioxide, methane and nitrous oxide, respectively.

EFFECT : The Greenhouse Effect
Drought is one of the effect that causes by the Greenhouse Effect, and it is driving current increases in food prices around the world, which means one day the price of grains might be higher than fuel. The number...
