1、 Environment Protection 1、Intruduce To develop the economy, but also protect the environment, which can balance the two? It can be said that there exist the contradictions is not only a short-term problem also a long-term problem.On one hand ,human must develop the economic,but the economic developm

2、ent is limited by the environmental protection on the other hand when people pay more and more attention to it. We must look at the issue dialectically.2、situation The development of mankind itself has long been confined to areas of economic development, and development of the natural environment an

3、d natural resources to rely on the support of the productive forces, and inevitably the quality of the environment have a negative impact. Half of the 20th century, the development of humanity has been a global threat to the environment for the survival of human beings.3 3、Question 1Resource crisisQ

4、uestion 1Resource crisis Oil resources will be exhausted Oil resources will be exhausted within a generation. Its reserves within a generation. Its reserves are not unlimited, easily are not unlimited, easily exploited reserves has been little exploited reserves has been little development of the re

5、maining development of the remaining reserves of more and more reserves of more and more difficult to continue to develop difficult to continue to develop to some extent lose value, the to some extent lose value, the energy crisis occurred.energy crisis occurred. Although coal than oil, but not inex

6、haustible. Instead of oil and other energy resources, in addition to coal, the large-scale use, little can. Although the inexhaustible solar energy, but too costly and time in a generation able to rapidly develop and widely used. Other new energy sources is also true. Forest resources is the main ad

7、vantage of the resources of the human. Rapid economic development the worlds forests in the larger environment is a lot of development. Forest resources to reduce the influence by many factors, but lead to reduction of forest area is the most important factor is the development of forest production

8、of wood and forest products like paper and building materials. Since a large number of consumer consumption of wood and forest products, thus reducing the global forest area is not only a countrys internal problems, it has become an international issue.According to statistics, in the 21st century, t

9、he worlds forests have a decreasing trend, and the demand for wood is increasing.There is no doubt that developed countries are the largest group of timber consumption. Of course, part of the wood consumption in developing countries should not be ignored.Question 2Environmental Pollution Economic de

10、velopment led to extensive use of energy, it brings mankind civilization and prosperity, but also give the survival of the human environment a great disaster.For exampleAcid Rain Heavy use of energy to enhance the human material, but also caused unexpected disaster, the second cause of acid rain dam

11、age, almost all over the world great harm.Some people think that acid rain is a silent crisis, but also the history of the impact of our most serious environmental threat, is an invisible enemy too. This is not alarmist.After 60 years, the stone statue of Germany has been thoroughly damaged by acid

12、rain.Question 3 Greenhouse effect There is no doubt that global warming is very serious consequences, such as glaciers melt, sea level rise, desertification, to the ecological system and the serious impact on agricultural production.If the sea level rise 66 meters many coastal areas will disappear i

13、n the bottom of the sea.Sea level rise the 24 meters from 1960 to 2010.3、 What should we do The earth is our common homeland. Good natural environment is the survival condition for human .So what should we do to protect our environment ?1. All countries should enact strict laws to protect the environment.
