Protection for Ozone Layer

According to StephenLeahy, in his article "Climate Change: Chemical Lobby Weakening Ozone Treaty", serious affects are caused by the huge damage of the ozone layer and the measure and attitude from different countries and companies. At present, the ozone hole is increasing rapidly year by year. That causes more and more people to get cancer, some of them even die. As a result of this, many countries have to sign a resolution to protect this ozone layer, in order to protect not only human's health, but also keep every species ability survive on the earth. Obviously, the damage to the ozone layer has been decreased because of the signing of this resolution. Some chemical gases from refrigeration can cause the ozone hole. Although some healthy chemical gases that can reduce the damage of the ozone layer have been invented, and are used for almost half of the world’s production, some producers and countries still do not change because of their own commercial interests. However, more and more places have responded to the UN's appeal, in order to create a green world (Leahy, 2009).
Nowadays, with the high-speed development of the society and industry, more and more productions have been created to satisfy people's requirements. As a result, the damage of ozone layer has been destroyed rapidly as well. Under this situation, people not only need to work for how comfortable and convinent their life is, they also need to think about how to protect the earth that we live in. So, I strongly agree with Leahy's opinion in his article. In my opinion, reducing the use of refrigeration which created ozone damaging gas, decreasing the use of private vehicles and enhancing dissemination of ozone layer protection are three main ideas, so that we keep a good environment for every species on the earth.
First of all, scientists have already found some new gas that can be used in the refrigeration with the same function as the old CFC, an ozone damaging gas. Because probably most people have to use the refrigeration every day, trying to change this new kind of refrigeration could be the first and most useful way to decrease the ozone destruction. Now, many people do not want to change their refrigerations because they do not want to waste more money to buy a new one with almost the same function. However, after reading of the increasing number of ozone hole areas and people with skin cancer caused by ultraviolet radiation, we have to think about the environment of the whole world instead of ourselves；therefore, changing the old ozone-damaging refrigeration as soon as possible, transforms our earth better and better.
Secondly, with the rapid development of modern industry and standard of living, many people have the ability afford the private car for themselves. Many vehicle producers increase their cars’ comfort and speed，in order to satisfy users’ requirements. Whereas this problem getting worse, the more vehicles that are produced, more gas has been used for these vehicle to work. Because the gas from burning oil also can destroy ozone layer, more vehicles run in the street means more destruction of the ozone layer. As a result, many countries enough their people to take public transportation, thus reducomg the burning of oil, and declining the ozone-damaging gas that is let into the atmosphere.
Finally, I think the basic and normal way to reduce the process of ozone damaging is to let more and more people know how serious it would be if our life without ozone layer. For some people, who do not understand what the ozone layer is, and why it is important to people’s life, they will learn the importance of it and think of solutions of this problem.
In conclusion, the damage to the ozone layer is one of the more serious problems for us currently, and also finding a way to solve it as soon as possible is still important and necessary. Trying to change to use a refrigeration without powerful greenhouse gases, taking more public transformation instead of private cars and making more and more people understand how it is important to improve the protection of the ozone layer is the solution.

Protectionism: Urgent problem in today’s world

With the development of the economy, the relationship between countries is much stronger than before. However the practice of protectionism, which means the government does its utmost to protect their industries just goes the opposite way of globalization. The prices are unstable because of the reduction of imports or exports. People have fewer choices than before. Also, some countries set up a wall to prevent personnel who come from other countries to occupy jobs in their nations. Even people who get well educated still can’t be employed by big companies abroad. In addition, free trade is making more interdependence among nations and mutual understanding among cultures, and can help countries to maintain political stability. In my opinion, economic protectionism is a real risk. Protectionism can increase the misunderstanding between different nations, and cut the world into many pieces. That is why I think protectionism has bad influences on our life, and it should be one the most urgent problems for the people.
