Global Warming

Nowadays, global warming is threatening the nature all around the world as well as human beings. However, people say that it isn't a problem that should be urged to solve. In my view, I believe that it is one of the most urgent problem that humans should solve.
First of all, the reason why humans aren't recognizing the danger of this situation is because the impact doesn't show on the surface. There are lot's of problems that are happening inside. What makes it more dangerous is that the damage that happens inside is unknown until it is too late. What makes it worse is that the danger is as bad as it can be. For an example, due to global warming, the level of the sea is rising. Even though it is a small amount, as time goes, it will become an amount that will threaten man kind.
Secondly, global warming must be stopped soon because of it's side affects. Global warming it self is dangerous enough to lead human race to extinction. With the side affects helping the destruction, we can't estimate what will happen. A current research done by The Massachusetts Institute of Technology announces that with the current rate of rise of temperature, more then 76percent of animal species will disappear from earth in only 50years. However, regarding the side affects, more then 84percent will vanish from earth. Thus, it is important to stop global warming as fast as we can.
To conclude, even though global warming doesn't seems that urgent right now, it can be thought of the most urgent problem. Most of it's damages are covered up, not letting humans to feel it by skin. Also, duels, due to the side affects, we don't know what might happen.
