At present, the greenhouse effect is more and more obvious. The greenhouse effect has the close connection with human beings. To some extent, the greenhouse effect is mainly cased by global warming. This speech will analysis the greenhouse effect from origin, influence and strategy. It will be helpful for people to know about and handle the greenhouse effect.
目前，温室效应越来越明显。温室效应与人类有着密切的联系。在某种程度上，温室效应主要是由全球变暖引起的。这篇演讲将从温室效应的起源、影响和对策三个方面进行分析。这将有助于人们了解和处理温室效应。
In the ancient time, the green house effect was not very serious, but now it is prominent. With the development of the society and economy, people’s social activities has already made the damage to some natural resources,especially some green plants. In the daily activities of human beings, people’s actions have enhanced the greenhouse effect. The scientists have already claimed that the greenhouse effect has the negative influences on people and the nature. So it is necessary to know about the green house effect.
Do you clearly know about greenhouse effect? The greenhouse effect has the obvious influences on the temperature. The average temperature of the earth has been increasing year by year. In fact, it refers to the whole earth is in the atmosphere which is fulled with the gases, especially carbon dioxide. These gases directly enhance the greenhouse effect. If there are not these gases, the whole world will come back in to the normal condition. (Bouwman, 1990).
The greenhouses do not mean the houses which are painted with green color. That is to say, the world looks like a house with some gases. The average temperature in the green house is higher than past, especially in the winter.
Some people do not really know the serious influences of greenhouse effect. Some people argue that the greenhouse effect is positive, it may bring more heat for people to live. In reality, it is of great importance that greenhouse effect has some negative influences on people’s life.
As time goes by, the greenhouse effect become more and more serious. First, it will make the whole earth warmer and warmer. The rising of the sea level is one prominent demonstration of it. With the rising of the sea level, many plants and animals will disappear in the world. The most important thing is that some countries and small islands will also disappear from the world. For example, Maldives is a very beautiful island in the southeast Asia. There are various animals and plants in it. However, with the greenhouse effect, the scientist predict that Maldives will disappear in the future (Mercer, 1978). Secondly, the plant diseases and insect pests will increase. The warm temperature is suitable for the growing and development of the insects and some diseases. The insects will do harm to the agriculture and people’s daily life (Lacis et al. 2013). If so, people will take more time and energy to fight against the insets and diseases. Third, the temperature will changeable and the storms of the ocean will increase. The changeable temperature will also harm to the plants and agriculture and animals. The ocean storms will bring some disasters for people. For example, the storm may case the serious flood, which will destroy some plants and people. Finally, the land dryness will appear more frequently (Raval, 1989). The desert area will enlarge a lot. For this reason, the water resources will also decrease accordingly. In fact, just certain higher temperature may cause serious negative influences on human beings and the relative nature resources.
The causes of this effect are various. The main causes are activities of human beings and the global warming.
First, with the development of the society, people have more demands for the natural resources. In order to meet these demands, people have to do more activities for the nature resources. With the support of the modern technology, people can get more sources from the limited resources. In this process, they have already damaged some natural resources.
Secondly, the global warming can directly cases the greenhouses effects. The global warming will make the temperature of the world become warmer and warmer.
Everyone should clearly know that the world people live in is becoming increasingly intolerable because of the effects of global warming. In fact, people has taken some actions to fight against the greenhouse effect, such as Kyoto Protocol, the actions of AOSIS. For this reason, people should also take measures to protect the earth. They can do a lot of things in daily life, such as taking the public transportation instead of private car, avoiding setting off the firecrackers, using solar energy equipment, supporting environmental protection commonwealth and so on. (Peters, 1985).
In conclusion, the greenhouse effect is more and more serious. The greenhouse effect has the relationship with global warming and people’s activities. People has done some things to fight against the greenhouse effect. However, it is not enough for people to do those things. There is a long way for people to protect the earth.
总之，温室效应越来越严重。温室效应与全球变暖和人类活动有关。人们已经做了一些事情来对抗温室效应。然而，人们做这些事情是不够的。人类要保护地球还有很长的路要走。
