Effect on environment Globalization has many impacts on the environment : global warming, climate changes and a drain on natural resources that affect our life badly. First of all, global warming and climate changes are the two most serious threats that globalization brings about. According to recent researchs, human activities, such as driving cars, using electricity from coal-fired plants . are contributing to global warming by adding large amounts of greenhouse gases to the air.While many greenhouse gases occur naturally and are needed to create the greenhouse effect that keeps the earth warm enough to support life,human use them as the main source of excess greenhouse effect. Then, these gases grow more heat and become trapped in the atmosphere so that the temperature of the earth is becoming higher and higher. This changes the climate and alters weather patterns, which influences the length of seasons and wildlife. The air is absolutely polluted,several storms and floods occur regularly. In short, global warming and climate changes are becoming more and more dangerous for our lives. Secondly, globalization also causes a loss of natural resources. With the development of worldwide industries, the demand for metals, coal and oil is increasing rapidly in many countries.Human have developed many technologies to help them survive and extract benefit from natural resourses.All technologies impacts badly on the ecosystem. People also exploit many other materials for agriculture, transport, housing and so on.Many rare species are on the verge of extinction, areas of land are reducing gradually. As a result,people will suffer from several disasters because many forests are disappeared,no more trees to research and so on.They do not realize that those resources are seriously devastated and may soon be used up in the near future. Because of those effects of globalization, we should find out some measures to protect our environment. In order to prevent global warming, we should reduce CARBON DIOXIDE in the air by burning less coal, using public transportation and studying renewable sources of energy.We also appeal others to plant more trees,use environment friendly products. Human can protect natural resourses by decreasing our consumption,understanding the true life cycle cost of different technologies,making ideas like sustainability part of our daily life. Besides, common position on the management of natural resourses might be good politics as it can be a conflict prevention and management tool. Governments should enforce laws against illegal exploitation so that natural resources might not run out. In conclusion, globalization causes bad impacts on our environment, in terms of climatic conditions and the decrease in natural resources. These proves put a strain on human life. Therefore, everyone should be aware of its drawbacks and take immediate action to save our environment. .
