the most important problems批改

The most important problems in today’s world will be solved in our lifetime.

We are living in a world having various problems such as war, environment and overpopulation. Do all the problems will be solved in our lifetime? The answer is not absolutely. People are always greedy and selfish, and they must have the benefit if they solve worldwide problems. My view will be supported in following discussions.

First of all, war is a very serious problem in the world. Even though the 2ed war is ended, there are still some disagreements among countries such as sovereignty and oil. It seems that we are incapable to live together in a peaceful world. Everyone in the world is not able to predict that the problem of wars will be solved in the future. Every country always does something or corporation in order to have benefits, and sometimes when the corporation does not work, the war begin. All in all, it is impossible that war will be stopped before our lifetime.

On the other hand, climate change results in the increasing of the world temperature which we cannot fix it. No one can deny that as the development of the technology, human beings are destroying the climate in the world; the world temperature increasing brings the flood and other natural disasters to us. For instance, in New Oreland, there was one of the biggest disasters in U.S, the hurricane. The hurricane brought the flood and storm that took over 1000 people’s life, and some factors of the disaster are in the climate change. Also, no one can promise such problem will not happen for ever.

That last problem cannot be solved in our lifetime is the over population. More people there are on the earth, more wastes and pollution accumulate. We cannot change it because we have to give up something if we solve the problem. For example, the world has 7 billion human beings, Chinese population have already been 1.3billion, and the pollution in China is a very big problem. People maybe maintain the pollution, but it still will expand. Therefore, overpopulation is a big problem that we have no idea to solve it.

In summary, a lot of problems in today will still exist in the future because people always consider the profits now.
