第一篇:环境保护英文作文

近几年来,我们可以明显的感觉到我们身边的环境污染愈显明显,环境安全问题已十分严重。因为我国以往的政策方针是重经济发展,轻环境保护,所以造成环境污染、生态破坏十分严重,主要表现为以下几个方面:

在大气安全方面,20世纪中叶以来,工业和交通运输迅速发展,造成了大气污染的日益加重。大气污染既危害人体健康,又影响动植物的生长,破坏建筑材料,严重时会改变地球的气候。据调查显示,我国每年因大气污染造成的经济损失高达1000多亿元。

在水安全方面,我国水污染问题十分严重,各地普遍存在着饮用水安全问题,直接威胁到人畜生存。近几年虽然投入大量的资金治理淮河等水域,但效果并不明显,整体情况仍在恶化。

在生物安全方面,大规模的外来物种入侵,严重威胁了我国的生物多样性。事实证明,盲目引进外来物种,会破坏环境平衡,严重时甚至带来灾难性的后果。同时,由于生态环境的破坏和对野生动植物的滥捕滥猎,生物消亡的速度正在迅速增加。

在土地安全方面,我国土地荒漠化和水土流失的情况已十分严重。另外,我国耕地质量下降非常迅速,同时由于过度使用农药等造成的严重的耕地污染现象,直接关系到我国居民的食品安全问题。我国是一个发展中大国,面对环境污染方面的压力不仅来自国内本身,还有来自国外一些发达国家施加的压力。因此发展经济和治理环境是一个需要我们长久面对的问题,而这也需要靠我们每个人的共同参与。

China’s Worsening Environment In recent years, we can clearly feel that the pollution of the environment around us is more obvious , environmental security issues are very seriously.We all know that our previous policy is the emphasis on economic development and light on environmental protection, that’s one of the main reasons that causes the

environmental pollution and ecological damage.Mainly show as the following aspects:

In atmosphere security.Since the mid-20th century, the rapid development of industrial and transportation has caused the increased air pollution which harm to human health, effect the growth of plants and animals, damage building materials, and even change the earth's climate.According to the survey,more than 100 billion yuan losses every year caused by air pollution.In water security.Our water pollution question is extremely serious.The

widespread around the drinking water security problems are threat to human survival directly.Although a large amount of fund has been put into these years, such as the Huai River and other waters, but the effect is not obvious, the overall situation is still deteriorating.In land security.The situation of land desertification and soil erosion is very serious.In addition, the quality of cultivated land in our country down very quickly.At the same time , the excessive use of pesticides has caused serious pollutions of cultivated land, which directly related to food safety issues of our residents.In the biological security.Large-scale of the alien species invasion is threatens to the biological diversity seriously.The facts prove that the blind introduction of alien species will destroy the environmental balance, even lead to catastrophic

consequences.At the same time, due to the destruction of the ecological environment and the abuse of illegal hunting of wild animals and plants, the speed of biological demise is increasing rapidly.China is a big developing country, and we are facing great pressures of the environment pollution which not only from the domestic itself, but also from some developed countries.So economic development and management environment is a need for a long time to face, which also need to rely on the joint participation of everyone.

Low carbon and environment protection

I Abstract There is one of the most sensitive global climate issues for years, which is global warming.In general, we know that the origin of global warming is the emission of carbon dioxide.It was verified that the relationship between carbon dioxide and temperature: when there is more carbon dioxide the temperature gets warmer.This topic should be discussed under current situation to advocate people concerning with this severe environmental issue.With the development of our living standard.Low carbon and environment protection are becoming a new lifestyle gradually.However, most of us haven’t known what low carbon and environment protection is.How to live a low-carbon life is also a problem to be settled.So it is necessary for us to make this view to be known by others and know more about green life

Key words: global warming low carbon environment protection green life

Introduction What mostly causes Climate change is burning fuel.Many years ago, burning fuel provides human warm, lighting and cooked food.It is a great process for human development.According to the speed of burning fossil fuels around the world, the service time of using fossil fuel is brief.Coal will be run out of in 200 years;natural gas can use 50 to 60 years and oil may only last another 45 years.Fossil fuel is the major part of primary energy at present.The quantity of exploiting and burning is large.Problems are coming.The process of exploiting coal is the most typical case of environmental impact that includes damage of land, countryside and water resources.Besides, burning fuels will produce carbon dioxide.Greenhouse effect and Thermal pollution threaten human’s living conditions.Our environment is of great importance for us human beings and we accelerate the development of the environment at the same time.But we have already produced a plenty of things which are bad for environment and ourselves.Such as carbon dioxide sulfur dioxide and so on.So we put forward the concept of environment protection and call on all of us to live a low-carbon life.However, lots of people didn’t do as they said.Because of this, we ought to take action right now, and everyone should do as much as he can.If we are able to make a contribution to our environment, it can make a big difference.This paper expounds the concept of low carbon and environment protection.What is more, it also involves the way to live a low-carbon life.In addition, it tells us what we should do to live a green life.It will help to improve our concept of low-carbon and environment protection.III 1.The concept of environment protection and low carbon

1.1 The concept of environment protection The life we live today should be leaded by environment protection, so it is necessary for everyone to establish the concept of environment protection.We human beings must protect the environment that we live today.What is more, we ought to realize that green life is always around us and we should peruse it all the time.Furthermore, the concept of environment protection should be seen from all sides.We must know the environment we live are pretty important and we need do as much as we can to protect it.The ways to improve the concept of environment protection are from two sides.1、To begin with, if we want to live a green life, we should restrict ourselves at first.Moreover, it is necessary for us to call on others to live a low-carbon life

2、The government ought to put forward a list of regulations to forbid others doing things that is not good for our environment.1.2The concept of low carbon

Low carbon, to us, is a lifestyle that we should try our best to make differences such as never wasting water, using less electricity, reducing the using of petroleum and any other way which can cut down the carbon dioxide content.With the increasing emission of carbon dioxin, the weather in the world gets warmer and warmer gradually.Some snow mountains are melting, and the sea level is rising.In order to stop it, everyone in the world needs to improve the concept of low carbon.Although many countries in the world have done a mass of things to make the concept be known by others, and lots of people have admitted it, the concept should also be strengthened.The concept is very important for our environment and future.In addition, we need to get together to protect our environment and strengthen the concept.So everyone should undertake the duty of environment protection and low-carbon.Only when we do what we said can we make a difference.IV 2.How to live a low-carbon life Low-carbon life, as we can see, is a life that we use less and less energy when we work and study in order to reduce the emission of carbon dioxide and sulfur dioxide.And it contributes to reducing the glob warming.It is a duty for all of us to live a low-carbon life.So it is of great necessity to know how to live a low-carbon life.1.When we study or doing something else, it is better for us to use energy-saving lamps not electric light.What is more, it is also a good choice to go to work by bike or by feet not by car.2.In order to save energy, we had better use low brightness when we use computers 3.If possible, we ought to watch TV occasionally and watch books when we have free time, for we can not only save the energy but also learn more things from books.4.It is better for us to use things that can be recycled, and we oughtn’t to throw battery randomly.It is easy to achieve the above requirements, but they play an important role in our low-carbon life.So we can do something which is considered unimportant at first and form a habit about it.And then we can live a green life.Air pollution is formed by many kinds of pollutant.Pollutant spread into the air all around.Primary source of air pollution is from factory emissions, automobile exhaust, burning reclamation and forest fire.The damage of air pollution involves industry damage, climate damage and disease.Atmosphere’s acidic pollutants and other chemical gases can corrode buildings and equipments.Besides, increasing floating dusts will product adverse effects during debugging and using equipments.Air pollution will increase the cost of industry production.On the other hand acid rain from air pollution influenced plants’ normal growth and result acidification.Serious acid rain will killed fish and decline forest.Transportation is convenient for human living, however, automobile exhaust pollution influence air condition.Air pollution also influences weather and climate.Rivers drying up and ozone depletion is derived from air pollution.Low-carbon life stands for a healthier, safer and simper lifestyle.Low carbon is not a behavior but a fashion today, and as students, we should take the responsibility at fist and call on others to live a low-carbon.We must make a contribution to the environment protection.V 3.The ways to achieve low carbon

From all these years, because of the dependence on carbon energy, the emission of carbon dioxin is increasing all these years, thus leading to the glob warming.It has great influence on the environment, economic and even the human beings.In order to settle the problem, low carbon is getting more and more necessary.So we can achieve low carbon from three sides.1.Low carbon of energy Low carbon of energy means that we can use some new energy which is not bad for the environment or have little influence on the weather.There are two kinds of energy that are able to meet our requirements.One is clean energy, such as nuclear and gas.the other is renewable energy, such as wind, solar and so on.2.Low carbon of transportation

The transport consumption today is thirty times higher than before, and the emission of greenhouse gas is so high that it has great influence on the weather.Faced with these difficulties, the change of transportation is necessary.Among all these ways to change the transportation, developing a new means of transportation is a good solution to reduce the emission of greenhouse gas.3.Low carbon of consumption Low carbon of consumption, as we can see, is a new way of consumption in life.It means green consumption, green packaging and recycling.Green consumption also means sustainable consumption;it is a new way of consumption that reduces the damage of environment and protects the ecological.Green packaging, which is a sort of packaging that can be cycled, is aim to reduce the damage to the environment, too.At last, cycling means that when we use something that can be used many times, we had better not throw it away right now and we ought to use it or give it to others, which is good for our environment.VI 4.The ways to achieve Environment protection In recent years, environment issues become more serious as speed development of region economic.It is an important measure of social development that protects the environment and maintains ecological balance.It is also the duty of every citizen.In the environmental science, it is stated that environment is the room around human and all kinds of natural factors that affects human life and development directly.In the millions of years of human history, environment played a big role in starting and developing the civilization of human being.Climate, water source, land and grasslands are material bases that make it possible for human to survive.Also, resources of forest and mineral provide human material to develop constantly.These environmental resources create the human civilization on the earth.However, when human being is making use of the material resources, our living environment has a series of environmental problems.―The publication of such literature as Our Common Future,‖ Zhu Zhongyuan wrote in his thesis in 2005 ―Care for the Earth, and 21st Century Agenda indicates that man’s awareness of water and natural ecological system has changed.‖

There are many lifestyles make more ecologically sound.Electrical energy saving is a way.The important environment protecting activity named ―My Earth Hour‖ is a typical example.Nowadays, we can try an activity named ―Unplugged on weekend‖.How can we unplug on weekend? Having a breakfast without microwave food and turning off mobile phones, computers, televisions, videos and washing machines.We can clean our rooms, write letters to our missing people, cooking a healthy food and read books.This beautiful unplugged weekend can let us turn to the healthy and environmental lifestyle.―Don’t hold things‖ is another environmental lifestyle.―Don’t hold things‖ has six points.Don’t take, don’t buy, don’t save, discarding, replacement and borrowing.Free things are usually not cherished and corner obliviously.Don’t use free plastic bags and free products without need.Don’t buy those things only if ―don’t need‖ products.If you buy many plastic products with cut price and feel satisfying, actually it is wasteful.Form a discarding habits and Learn to find other replacements before buying new products.We also can borrow rarely-used things from others.The third way is low-carbon lifestyle.Using traditional spring wound clock instead of electronic clock.Turn down computers especially displayers when you don’t need them as do any other appliances.Doing exercise without electronic machine and ride bikes rather than drive cars.A neoteric thought of environmental lifestyle is don’t divorce.Breaking a marriage aggravate global warming problem.After divorce it needs more rooms, electric power and water resource.These lifestyles can be more environmental for our earth.VII Public participation is a good way for resolving environmental conflict.Communication roles of public participation can give many thoughts to governments on the internet.Websites can increase environmental protection ways for general public.Media’s function cannot be ignoring.Participator can let public participation have chances to participate in environmental activities.But it has a big problem is that too many opinions so it is difficult to comply with each thought.Environmental issues should be reducing nowadays.We should protect environment while human is developed at the same time.People create ethics to remind environmental awareness.For each person, healthy and green lifestyle could help our life sustained.People also can devote themselves with their works.Resolving environmental conflict needs public participation.That is government’s responsibility.VIII 5.Conclusion

In conclusion, global warming has hazard to cause sea level rise and climate change: it leads to the extinction of plants and animals, while hinders people’s daily life and threatens human society.It also has few positive effects which leading people to focus on reuse, reduce, and recycle.It calls for global concentration that every country takes action to preserve the earth ecosystem.This essay consequently addressed people requiring nurturing the consciousness to conserve the sources, enlightening people to preserve the planet.If people can comprehend the details of Low carbon and environment protection well, they will realize the significance to protect the environment and what we should do in our daily life.If we want to make our environment more beautiful and make our life green.So we should do things even if they are considered to be unimportant and call on others to take part in the environment protection.We believe that environment protection and low carbon can be a part of our life, and we can set up a harmony, green and healthy life.We can make the life style become a fashion.The more attention we paid, the better world will be.IX 6.References Brown, Lester.Plan B: Mobilizing to Save Civilization.New York: Carroll and Graf Publishers, 2005.Print.Keppler, Frank.―Global Warming: The Blame is not with the Plants.‖ Max Planck Institute for Nuclear Physics, Heidelberg.18 Jan.2006.Lecture.Revkin, Andrew C..―Global Warming.‖ New York Times.20 May 2010.Web.10 June 2010.Agenda 21: The Earth Summit Strategy to Save Our Planet.Boulder: EarthPress, 1993.[I.A] ―Are You A Green Consumer?‖ Consumer Reports 57, no.11(November 1992): 704–707.[III.C] Bernards, Neal, ed.The Environmental Crisis—Opposing Viewpoints.San Diego: Greenhaven Press, 1991.[IV] Cebon, Peter.―Corporate Obstacles to Pollution Prevention.‖ EPA Journal 19, no.3(July 1993):20–22.[III.A] Cohen, Mark A.Management 5596: Management of Environmental Issues(syllabus).Vanderbilt University, Nashville, March 1993.[V.A] Mitsch, William J.―Ecological Engineering.‖ Environmental Science and Technology 27, no.3(1993): 438–445.[II.A]
