There is an urgent need for a "civilized, harmonious and healthy" composition, about 1200 words, thank you ~ ~

As an important part of the natural environment for human survival, any change in climate will have an impact on the natural ecosystem and socio-economic system. At present, in the face of the worsening climate phenomenon, its negative effects are more concerned, because the adverse effects may endanger the future survival and development of human society. Nowadays, low-carbon economy has become a hot issue, which should be expected. The combined forces of internal and external factors are pushing China towards the era of low-carbon economy. On June 5th, this year in World Environment Day, the theme of China was "Low Carbon Emission Reduction, Green Life". As a citizen of China and a member of the global village, each of us must shoulder our due responsibility and mission to build our green home!

Perhaps many people still don't understand the difference between Copenhagen and Haagen-Dazs. Perhaps there are still many people who think that The Day After Tomorrow and 20 12 are purely fictional American blockbusters, and that the global warming conference is only international news that has little to do with themselves ... In fact, when the global political elite is fighting for the last chance for mankind in Copenhagen, Denmark, the devil derived from global warming has already.

"Now the weather forecast is becoming more and more difficult to do. Weird weather is always against the law and unpredictable. The so-called law in the past was always changed by reality! " Dr. Wang Jijun, deputy director of Henan Climate Center, lamented, "Every accurate forecast condenses the wisdom and sweat of meteorologists!"

Dr. Wang Jijun can easily find evidence for his exclamation-

At the beginning of June, 2009, it was 5438+065438+ 10, and autumn in Zhengzhou seemed unwilling to leave at all. The sunshine is warm, the trees are lush, and people wearing short sleeves can be seen on the street. However, on June165438+1October 10, the temperature plummeted and a snowstorm broke out that night. 1 1 At about 9 o'clock in the evening, there was heavy snow all over the sky, and suddenly there was lightning and thunder! On June 5438+02, the snowfall and the depth of snow in Zhengzhou reached a "record high"-exceeding the daily record since the meteorological record.

On April, 2065438 10, visitors to Luoyang will marvel at the "wonders" of peony in the snow. In the days around this day, Luoyang was sunny and full of spring.

Global warming brings not only dust, but also extreme weather such as snowstorm, cold current, rainstorm and heat wave. Experts predict that the global climate will be further warmed, and the degree of warming is likely to increase. The American magazine Science published a new research result, saying that after 2009, the global average temperature will exceed the historical maximum of 1998 in at least half of the years, and more extreme weather will occur frequently, so human beings have to face the test of ice and fire in the northern and southern hemispheres. At the same time, the United Nations assessment report reminds us that if human beings do not pay attention to environmental protection, the average temperature will rise by 6.3 degrees Celsius at most by the end of this century. What a terrible number is this? Simply put, if the average temperature rises by 3 degrees Celsius, in Asia alone, more than 7 million people will face floods every year. If the temperature rises by 4 degrees Celsius, there will be more than 3 billion people in the world, facing the problem of water shortage.

Since last autumn, severe drought has occurred in southwest, south China and parts of south China. In the southwest of China, where the rainfall is the most abundant, most areas are dry and lack of rain, and Hiderigami is rampant. Farmland cracked, ponds and dams dried up, and rivers and streams were cut off ... On March 23, the statistics of the National Defense General showed that the population with difficulty in drinking water due to drought had reached 227 10000, of which Yunnan, Guizhou, Sichuan, Guangxi and Chongqing had the worst drought 18005. The drought-affected area of cultivated land in China is 1 654,380+0.4 million mu, of which the drought-affected area of crops is 87.96 million mu (with severe drought of 27.98 million mu, 1 386,5438+0.000 mu); The water-deficient soil moisture of the cultivated land to be sown is 2610.2 million mu. Among them, the drought-affected area of cultivated land in the five southwestern provinces reached 96.54 million mu, accounting for 85%.

In addition to drought, abnormal climate and global warming, many problems need to be solved urgently, such as water shortage, deterioration of living environment, increased economic losses, rising sea level, threats to human health and intensified species changes.

Facing the global warming crisis, as college students, we should also do our part for the motherland and the world. We can't stop the temperature from rising, we can't control the melting of polar glaciers, and we can't avoid the drought in Yunnan. Because they have already happened, we can only minimize the impact of disasters on us. With the convening of the Copenhagen conference, which is known as "changing the fate of the earth", the popularity of the key words of "low-carbon economy" at the two conferences, and the propaganda of low-carbon by TV, newspapers, internet and other media, the concept of "low-carbon" has been deeply rooted in people's hearts and is well known by all walks of life and the general public.

Developing a low-carbon economy and building a low-carbon city is not only a matter for the government and experts, but also the responsibility of every citizen to actively establish a low-carbon life concept. "Low-carbon economy" not only means that the manufacturing industry should speed up the elimination of backward production capacity with high energy consumption and high pollution, and promote scientific and technological innovation of energy conservation and emission reduction, but also means guiding the public to reflect on which habitual consumption patterns and lifestyles are bad hobbies that waste energy and increase pollution, so as to fully explore the great potential of energy conservation and emission reduction in service industry and consumer life. Low-carbon life is a natural habit to save all kinds of resources around you. We should actively advocate and practice, pay attention to energy saving, fuel saving, solar terms, garbage collection and green travel, starting from bit by bit and starting from every energy-saving detail around us. Many low-carbon lifestyles can be achieved by everyone, even if it is a small contribution, which is a support for developing a low-carbon economy and building a low-carbon society.

To realize the grand strategy of saving energy and reducing consumption may depend on many nuances. People should see that this "nuance" is not only the details of many energy-saving technical improvements such as manufacturing and construction, but also many energy-saving details in daily life habits. For the most populous country in the world, everyone's living habits seem to waste little energy and carbon emissions. Once calculated by many population multipliers, it is a huge amount. Science and technology workers and social science workers have the responsibility to carry out creative activities and popularization of low-carbon economy and low-carbon life to the public from all aspects of daily life, so that the scientific development decisions of "energy saving and emission reduction", "building a resource-saving and environment-friendly society" and "strengthening the ability to cope with climate change and making new contributions to protecting the global climate" put forward by the 17th National Congress of the Communist Party of China can be transformed into practical actions of the whole people. Developing low-carbon economy is China's responsibility as a "citizen of the world", and it is also a rare opportunity for China's sustainable development and transformation of its economic development model. Therefore, it is our responsibility and mission to advocate a low-carbon economy and improve our lifestyle.

Low-carbon life represents healthier, more natural and safer, and it is also a low-cost and low-cost lifestyle. Low carbon is not only a corporate behavior, but also a lifestyle that conforms to the trend of the times. As college students, what we can do at will is: surf the internet less, don't stand by in class, and turn off all the power when going out. Use instant messaging tools such as e-mail and MSN more, and use fax printers less; Try to use and not use disposable toothbrushes, disposable plastic bags and disposable water cups as little as possible … because the oil used to make them is also disposable; Walk as far as possible when going out, start from low carbon and start from yourself. At the same time, take the initiative to participate in the national college students' energy saving and emission reduction competition, and make full use of what you have learned to contribute your strength.

Under the background of global warming, "low-carbon economy" based on low energy consumption and low pollution has become a global hotspot. Energy conservation and emission reduction are imperative, and low-carbon development has gradually become an inevitable trend of social development. Low-carbon life is not only an attitude, an obligation, but also a responsibility. China is a responsible country, and a responsible country must have responsible citizens. We should not only advocate a low-carbon life, but also actively practice it.

Because there is only one human on the earth, it is our common responsibility and mission to choose a low-carbon lifestyle.

Young college students have a wide range of knowledge, are full of vigor and vitality, tend to be rational in thinking and understanding, are keen on practicing low carbon, have a sense of social responsibility of "connecting the past with the future", are the new force and pioneer force of "low carbon development", and are the best practitioners and propagandists. Save every drop of water and let us have a bluer ocean! Save every kilowatt hour and make more corners full of light! Advocating energy conservation, low carbon and environmental protection requires the concerted efforts of you, me and Qi Xin. Let's take action, with our wisdom and hands, actively join the ranks of energy-saving and low-carbon, and spread the environmental awareness of energy-saving and low-carbon to everyone around us. Let's join hands, * * * with a sense of mission, take active actions to set an example for the construction of green and conservation-oriented gardens and contribute our own strength.
