Environmental Protection

No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way.

There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.

It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .

People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced snowfree(无雪的) winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer daysg.

The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts, severe storms, hurricanes (飓风). People suffer a lot from disasters relevant to global warming.

To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.

With the development of economy, more and more greenhouse gases are being discharged into the air. CO2 makes up about 70% of the greenhouse gases, which is considered to be one of the greatest causes of global warming. It has harmful effects, causing the sea level to rise and many natural disasters to strike. So we must take effective measures to save our planet. First, we should use more clean energy and less coal and oil. Second, we should go to work on foot or by bus instead of driving a car if possible. Third, we should plant more trees, because plants can turn CO2 into oxygen. More importantly, we should form the habit of saving energy in our daily life.

As more and more countries become industrialized,global environment has been inevitably changed.And we are just experiencing the altered climate.Human activity is affecting global climate.Many scientists have predicated that global temperature will continue to rise in the foreseeable future because greenhouse gas emission is still increasing.

Now there is a growing awareness that climate change is definitely not confined to a certain region or country.

However,it is a problem all countries are involved.Most people would agree that as the planet warms and the sea ice is melting,polar bears are vulnerable to lose habitat,even

threatening our home around the coastal areas.It is time we took measures to protect our environment.

There is no denying that industrial emissions have been the dominant influence on climate change for the past 50

years,overwhelming natural forces .To improve this situation, First of all, Ultimately, we,everyone on this blue planet are supposed to promote and carry out"low-carbon"lifestyle as an obligation.Secondly,carbon emission reduction must be put into implement,especially reducing fuel consumption and exhaust emissions,and it a wise choice for us to use renewable energy resources.Moreover,global climate summit are expected to play

a significant part in urging involved powers to Carry out the state strategy of sustainable development so that our environment can be back to normal gradually.

Greenhouse gas emission is but one of the many effects for the climate change.Another is excessive deforestation.And the Amazon tropic rain forest has seen man's greediness.Just imagine what would be like if our forest coverage rate were what it was 20 years ago?The answer is quite clear that global temperature would be lower and many species may not die out.Therefore,we must quit using disposable packaging and dishware and encourage of employment of

environmentally-friendly materials.Besides,people ought to develop an awareness of environmental protection and cherish forests resources.Of course supporting recycling is also a good alternative way.

In present case ,yet it could go a long way for us to recover our environment from climate change,we are obligated to

dedicate ourselves to go for a harmonious planet.In addition,we have every reason to try our best to protect our environment.I believe the new environment is in store with our efforts.

The Global Warming.

People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. Places which used to be abundant in snowfall have frequently experienced snowfree winters. Drought lasts longer in some dry areas. People find that without air conditioners they could hardly work or fall asleep on hotter summer daysg.

The side effects of global warming are alarminS. A warmer global climate melts the ice caps, raising sea levels. What is more, it disturbs weather patterns, causing droughts severe storms, hurricanes . People suffer a lot from disasters relevant to global warming.

To stop global warming we should make immediate and continual efforts. We hope the situation will soon change. Global warming catches and holds our concern, for it affects us and will affect our later generations. We cannot wait any longer. Do it. Do it right. Do it right now.

In this report, I learned a lot of things, but my first thought is that the cause of global warming is carbon dioxide increases.

Why is carbon dioxide will increase? I think the reason is that people often feed drive, raising livestock, factories discharge smoke... And so on. But these are all can be solved together, perhaps can improve the earth continued warming, for example: close to the destination can ride a bike, Destination is far away, you can use public transport; Livestock waste processed into Hanoi again; Factory can build a waste treatment plant... And so on.

Please do not underestimate the power of carbon dioxide, wait until the sea level rise, urban flooding and flooded farmland, in the end would have faced the crisis of insufficient food. Please join me shout: "stop hurt the behavior of the earth! The earth on which we live is only one."

The cold winter has passed, but this winter with snow is not, is not how cold the weather, why is this so?

I asked my mother, my mother said: "I don't know, you go online to check." I opened the computer, input -- global warming. There have been many answers on the layout.

Because of human destruction of forests and other greenhouse gases from the burning of when, because these greenhouse gases with high transmittance in the visible light radiation from the sun, and the earth is reflected is highly absorbent, can strongly absorb infrared radiation on the ground, the greenhouse effect is often said that the "". Global warming may lead to consequences, will lead to a global redistribution of precipitation, melting glaciers and permafrost, rising sea levels, damage the balance of the ecosystem and the human food supply and living environment.Global warming is not only harmful to humans, but also endanger the survival of animals. For example, the polar bear, because of global warming, melting glaciers and polar bear hunting fish more difficult, and the ice melting fast, this continues, sooner or later the polar bears extinct species like the polar bear, Arctic wolf, Arctic animals are penguins.

Want to stop global warming, we should save every drop of water; plant more trees to reduce desertification; do not use disposable convenient bag; reduce the emission of carbon dioxide. I appeal to our homes, we act together now!

Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.

What should governments do to help prevent global warming? Give reasons for your suggestions.

The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.

Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.

Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.

Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.

In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

When global warming, the world have changed dramatically.

The Antarctic ice and snow melt, human feeling will be under water, it is human to take the consequences. Arctic overlord, the polar bear also gradually extinction due to global warming. Has been the mother to a pair of scissors to bear, baby bear curiously ask: "mother, with scissors stem what ah?" Mom replied in a tone of command: "quick shearing, longer so thick hair will be hot dead!" Naive to bear looked at his mom, "we live in the ice and snow, how can heat? This is our coat, without it will be cold, can't cut!" Mother bear tone with a sad and sigh: "global warming, in does not adapt, now I'm afraid go!"

Global warming, the polar bear can't find food, even little bear, it is be compelled helpless! Humans shall make profound reflection to your behavior, but, when global warming, human couldn't realize his mistake! Only know no longer suffer from the cold in winter, the temperature rose, the cold has gone, only the immediate interests, didn't know that will be far away from the white snow, originally should be open the flowers in the winter.

When global warming, I hope this to human consciousness already consequences. Early up, to stop all this happen!

As is subtly revealed in the cartoons above, global warming is a real threat to our world. In the first drawing, the glaciers in the polar region are rapidly melting owing to global warming. In the second picture, a homeless polar bear is staying on an isolated big block of ice.

The purpose of these portrayals is to show us that global warming is a looming threat to people all over the world. To begin with, global warming leads to the rise of sea levels. Large sections Chinese coastal regions would gradually disappear under rising sea levels because of global warming, severely impairing the country’s social and economic progress. China’s long coastline is the base for about 70% of the large cities, over half of the domestic population and nearly 60% of the national economy. With comparatively-advanced social, economic and cultural developments, China’s off-shore regions will suffer great losses if the sea level does not cease rising. In addition, global warming increases the possibility and intensity of extreme weather such as hurricanes and snowstorms. Hurricanes and typhoons have become stronger and longer-lasting over the past 30 years. These upswings correlate with a rise in sea surface temperatures due to global warming.

Taking into account the devastating effects of global warming, we can draw the conclusion that global warming is a great threat to our world. Facing the growing menace of global warming, more scientific and active preventive measures should be taken on a larger scale to change for the better.

With the development of economy,more and more greenhouse gases are being discharged into the air.CO makes up about 70% of the greenhouse gases,which is considered to be one of the largest causes of global warming.It has harmful effects,causing the sea level to rise and many natural disasters happening like droughts,severe storms and hurricanes.

The side effects of global warming are alarming,so we must take effective mea-sures to save our planet.First,we should use more clean energy and less coal and oil.Second,we should go to work on foot or by bus instead of driving a car if possible.Third,we should plant more trees to turn CO into oxygen.More importantly,we should Tomm the habit of saving energy in our daily life.Global warming catches our concem.Only in these ways,can we protect our planet.

I often see on television, network is now the holes of the earth has been destroyed by human, if we are in different heart to protect it, the destruction of the earth will be completely in the near future. Faster and faster, with the development of human science and technology science and the negative effect gradually manifested, then let me give you a few examples to illustrate why experts predicted that the earth will be gone after so many years.

First of all, global warming is one example, soak in the hot weather in summer air conditioning becomes a new "hobby", but what do people ever thought of air conditioning can bring negative effect? Gas air conditioning to contain large amounts of methane, to the outside is the leading cause of global warming gases, methane and air conditioning will waste a lot of electricity, so try to avoid using the air conditioning or appropriate use.

Another reason is that carbon dioxide, automobile exhaust and factory waste gas containing a large amount of carbon dioxide, and carbon dioxide are most likely to lead to global warming. Cars now, too much exhaust serious affect our nong cough, throat inflammation... . According to concerning sectional statistic China's per capita emissions of carbon dioxide emissions every year 2. 51 tons a year! The changes in the harsh environment around us.

More important reason is that: reduce forest, farmland, water damage and serious water pollution, fresh water supply is a problem, many parts of the draft has become a big problem. Now countries are massive effort, demanding, and costs "of the south-north water diversion project".

In order to save the planet, people all over the world should be: don't open air conditioning, use recycled environmental protection bags, don't use plastic bags, take the bus, don't throw waste batteries... Such as the dribs and drabs in life. In fact, environmental protection is not difficult, as long as you support is the best gift you give earth environmental protection, take action, this is a powerful force!
