Scientists predict that the rising temperature of the Earth will cause the melting of glaciers in Antarctica and Arctic. The sea levels will rise, completely flooding many islands, a large part of the Netherlands and many coastal cities such as NY or Miami. People who are now living in these areas will have to move inland, many species will be eradicated.

The solution is that we have to lower the production of carbon dioxide immediately, try to reduce our carbon footprint (measure of all greenhouse gases we individually produce) we should for example start to recycle, separate plastic and paper and try to behave more ecologically. Now, it’s trendy to be ecological and to recycle the waste. There are 3 main containers - blue for paper, green for glass and yellow for plastic - almost everywhere. I think it’s useful, because the waste can be recycled and used again.

The next global problem is air pollution. It’s also connected with the global warming, mainly with the carbon dioxide production, but the air is polluted also by other dangerous gases and chemicals. Cars and heavy industry exhaust gases contributing to smog and acid rains. Acid rains are caused by a combination of nitrogen mixture and sulfur dioxide with water in the atmosphere. They damage the nature, poison the lake water and make fish die. They also destroy the trees and plants.

Another global problem, also very closely connected with the global warming, is the problem of the depletion of the ozone layer. The ozone layer, composed of O3 molecules, is being damaged by freons. This is very serious, because the ozone layer absorbs the dangerous ultraviolet light from the sun, this protects our skin and eyes. But when there is an ozone hole, the ultraviolet rays come to the Earth and it can damage our health. I think this was the global problem of the last decade, because the cause – freon – was found and it isn’t allowed to be produced anymore.

Another global problem, also very closely connected with global warming and climate changes, are natural disasters, such as earthquakes, floods, hurricanes, tsunamis, fires, volcanic eruptions or droughts. Natural disasters usually have many casualties and cause famine, poverty, homelessness and violence.

Global problems aren’t only environmental, but also social. Some of the current social problems are, for example, racism, terrorism, unemployment, mutated viruses and diseases, drugs, illiteracy or violence against women.

I think that globalization is mostly a positive process. We can use recent events in Japan as an example. The local earthquakes and tsunamis have had the global effect. Because of a damaged nuclear power plant, radiation spread into other countries but thanks to the international sharing information, people could protect themselves. It is also going to have a long lasting effect on the world’s economy because Japan was one of the biggest powers and a lot of products, for example computer components, were made there. But many of these factories were destroyed. We can see the influence of the globalization even on the fact that Japan asked other countries for help and the whole world sent them money, food, clothes and other needed things.
