The most important problems in today’s world will be solved in our lifetime.
With the development of science and technology, our life is of great convenience. However, life also bounds with problems, since the development is exchanged with the cost of the consumption of energy and bringing lots of contamination. Although there is a growing awareness of finding solutions for these problems for people all over the world, I still disagree with the statement that the most important problems in today’s world will be solved in our lifetime.
The first reason I want to put forward is that these crucial problems, which can never be caused by a short time, inversely, are formed during the whole period of the development of human beings. Global greenhouse effect, which is induced by the released carbon dioxide from the burning of fossil fuels since Industry Revolution, means that the balance of oxygen and carbon dioxide in the atmosphere have already been broken up and consequently brings horribly bad influence in many aspects of our daily life. We have been aware of this terrible problem for a long time and create numerous effective ways to decrease the discharge of carbon dioxide, which can just prevent the greenhouse effect become worse. However, how to absorb the large amount of carbon dioxide that already existed in the atmosphere is still extremely difficult for us. As a result, we can hardly return to the balance in a relatively short time. This example makes me realize that any important problem can never be resolved in our lifetime.
In the second place, not all of the people around us have the consciousness of doing useful actions to contribute to the world’s problems. Everybody knows that the desertification has the tendency of becoming more serious for complex reasons, such as a large amount of deforestation and planting crops in dry sections. Impossible that going to the desert to plant trees for people who live in big cities is, they can still have little contribution, and then accumulate every little contribution to solve the
