global warming

In the 21th century human beings are facing many natural disasters such as earthquakes, flood, hurricanes... Those disasters have a huge impact on our life and on our planet. Global warming is one of them and it probably is the most destructive one.

Global warming is a process in which temperature of earth rises due to intensive carbon emission to atmosphere from burning of fossil fuels, industrial wastes, and agricultural chemicals. As a result of this greenhouse gas accumulation in the atmosphere, drastic climate changes occur all around the world. These gases have been occuring naturally since the begining of time but that was not a threat since they were being absorbed back by nature again. (Socha,n.d.par.1) Unfortunately this balance has been degraded, especially in recent years, because of humans.

Our desire to consume as much as possible, live in better and more comfartable conditions and control the nature the situation led us to destroy forests, increase industrial production (and therefore industrial wastes) and come up with new technologies that allow us to fly or make our air cold in summers. The problem is that such benefits do not come for free. Every time a plane takes off, someone turns the air-conditioner on or puts on too much deodorant; more and more carbon gassees are being released to atmosphere. We have been living recklessly like that for quite some time now, and unfortunately accumulation of higher concentrations of greenhouse gases had enhanced our earth's heat trapping capability. Today we have to face the results of global warming and its effects and take the necessary precautions to prevent further damage.

As a part of the ecological system, wildlife is also affected. Many species became extinct and at least as many of them are facing with extinction because their habitats are damaged. (Peters,2003)Especially in the last thirty years, many animal species has changed their habitats and polar bears in Alaska are a good example.
