Although today's developed earth environment looks optimistic, there are very serious hidden dangers, which are all man-made: cutting down trees at will, setting up chemical plants, and discharging harmful liquids at will. "The world emits more than 600 million tons of gas that poses a greater threat to mankind every year. . . . . ; It is estimated that by the middle of the next century, one third of the earth's surface will be in danger of desertification, and 6 square kilometers of land will be desertification every year, threatening more than 60 countries. . . . . "What do humans think of these shocking figures? From 23 million years ago to the appearance of forest apes 6.5438+0.8 million years ago, and then to the highly developed civilization era of mankind, nature has always been "responsive" to everyone, which has further bred human greed.
For example, the Mulan River in China was originally a crystal clear river in the early 1950s, but now it has become a polluted river, and fish and shrimps have disappeared, adding another scar to our mother earth. Isn't this a wake-up call for mankind?
Therefore, I solemnly suggest to people who haven't realized it:
First, if human beings want to conquer the terrible nature, they must respect it. We should not only be cautious about transforming nature, but also boldly practice and improve it, so as to control nature and make our own interests develop harmoniously with nature. We must never repeat the mistake of "polluting first, then managing" in western developed countries.
Second, starting from me, first choose a lifestyle that is conducive to protecting the environment. Be kind to our home and the earth and create a beautiful living environment.
1。 Save resources and reduce pollution
(1) Be proud of saving water. Turn off the tap at any time to prevent dripping.
(2) Use detergent carefully and use soap as much as possible to reduce the pollution of chemicals in detergent to water quality.
2。 Green consumption and environmental protection choice
(1) Use unleaded gasoline, cadmium-free lead batteries and phosphorus-free detergents to reduce water and air pollution.
(2) Buy low-priced household refrigeration appliances and hairless mousse to reduce the pollution to the ozone layer.
3。 Multiplexing and reuse
Try to use disposable goods less and use durable goods more. If disposable plastics and lunch boxes are not used, white pollution will be reduced; Do not use disposable chopsticks; Bring your own shopping bag or basket.
4。 Classified recovery and recycling
Do not throw waste batteries, waste plastics and other garbage and waste; Classify garbage, turn waste into treasure, recycle resources and benefit mankind.
5。 Protect everything in nature.
Do not hunt and use rare animals and protect animals, and cherish and protect wild animals and plants; Afforestation, care for every inch of green space, every flower and every tree around you.
6。 Pay attention to hygiene and protect the environment.
No spitting, no littering, no smoking and no noise in public places.
As a primary school student in the new era, I advocate students to improve their awareness of environmental protection, and also suggest that uncles and aunts join our team to contribute to environmental protection and benefit future generations. Because: protecting the environment is urgent!
Environmental protection suggestions
SECRETARY FOR ENVIRONMENT PROTECTION:
Hello!
I am a pupil in XX Primary School.
I grew up in the mayor of XX, and I saw the changes in the city of XX. From an unknown city to Greentown in China, a folk festival and the South Expo were held.
Now in Nanning, "everyone is responsible for environmental protection" and so on can be seen everywhere. By the roadside, all kinds of trash cans are very beautiful. Recently, everyone advocates separating recyclable and non-recyclable trash cans.
However, I think classification alone is not enough. It is necessary to write down some recyclable and non-recyclable garbage on the trash can. Not everyone accepts as much knowledge as we do, knowing what is recyclable and what is non-recyclable. Think about migrant workers, and it is not good to throw them around if they don't know. Not only can it not play the role of environmental protection and garbage sorting, but it will bring trouble to the workers in the garbage dump.
In addition, I also found a rather serious problem.
One day, my mother and grandmother and I went by bus, and wanted to go to the martyrs cemetery to sweep the graves. At first, we were happy to go out, but when we arrived at the bus stop and waited for the bus, we found a trash can next to it, and the garbage inside stinks. Passers-by walked up and down with their noses upturned, and we smelled a great stench when we passed by.
Everywhere I went later, I would carefully observe whether there was a trash can. After a period of observation, I found that the garbage bins are fixed now, unlike the ones that can take out the garbage before, but why does it smell bad? Later, I learned that it was because the garbage can was repaired. When the sanitation workers clean the dustbin in the morning, they simply pick up the garbage on the surface, but they don't clean it up to the end. Once, I asked them why they didn't clean up the garbage. They said it was not because they didn't want to, because the trash can was fixed and couldn't reach the bottom, so the garbage couldn't be poured out, so they had to leave it inside.
It can be seen that the garbage can stinks, not because the sanitation workers are irresponsible, but because there is something wrong with the design of the garbage can. I hope that for the beauty of XX city and the fresh air, please ask Uncle Mayor to design some practical and beautiful trash cans, so as not to let those unpleasant smells pollute our fresh air again.

Proposal for campus environmental protection civilization
In order to welcome the 2008 Green Olympics-People's Olympics-High-tech Olympics, and for the global fitness, it is suggested that all students and faculty in our school should start from me, from classes, dormitories and families, and put all aspects of daily life and work into a civilized, scientific, healthy and beautiful track of environmental protection. Understand and act mainly from the following aspects:
1. Save resources, water and electricity everywhere in life, work and study. And start from scratch, put an end to all kinds of loopholes and dead ends that consume and waste resources; Every link in the consumption and use of materials and materials should be frugal, scientific and reasonable, and environmentally friendly-that is, the whole process from shopping to use (consumption) to the end should meet the requirements of green, ecological, environmental protection, harmlessness and resource recycling.
2. All recyclable materials, such as waste paper, waste plastics, waste metal, etc. , should be classified and recycled as much as possible to realize the recycling of resources, thus saving resources and reducing garbage pollution. Therefore, it is suggested that all classes, dormitories and other units should set up garbage recycling bins ..... The recovered funds can be accumulated for physical fitness, art and science. Shuttlecock kicking is a simple, feasible and comprehensive activity in fitness activities. This item should also be extended to the family life of all members of the school.
3. Study hard, master the concepts and knowledge of modern science and technology and advanced culture, and learn to master relevant environmental protection knowledge and technology; It is necessary to fully understand the seriousness of the current national and local and global environmental problems, raise the awareness of protecting the same home of mankind, realize that "there is only one earth home in the world-everyone has only one body, and all kinds of things should be saved and recycled" (from Netease Environmental Protection Forum), and fully understand the significance of developing circular economy, establishing circular society and circular life to the ecological environment; Love peace, love nature, establish the consciousness that there is no family happiness without everyone's beauty, and establish environmental ethics and legal consciousness; Pursue the capitalized life values with lofty meaning and unlimited value, and promote the harmony between man and nature, man and society, and man and spirit-that is, self-health, bodybuilding and harmony. In a word, through continuous study and hard work, we are determined to become a person in the new century who is beneficial to the earth's environment and the sustainable development of mankind.
4. Society is a university, and the above measures are equally applicable to all parts of human society. I hope that students and colleagues will not only learn from themselves, but also spread the concept of environmental protection and health in the new century to all directions of the whole society, so that everyone can know and do it. ......
Students and colleagues, in the face of the global village era in the new century, which is closely related to globalization, Beijing 2008 is not far away from us ..... Let's make concerted efforts and cheer for the "same song" of all mankind and even the whole universe with practical actions! Waste of resources:
Water, the basic substance on the earth, deserves our praise! She gave birth to the world and all sentient beings; It is she who provides energy for life and makes life survive; Or did she let life develop continuously and become more and more prosperous? Therefore, it is no exaggeration to say that "water is the source of life".
But is water inexhaustible? We can definitely answer: No, although 70.8% of the earth is covered with water, 97.55% of the water is seawater, which can neither be directly drunk nor irrigated. Of the remaining 2.5% fresh water, the water that humans can really use is less than 1% of the global total fresh water. It is true that from the appearance of primitive life on earth to the present, water has been serving life, working hard and never stopping. But I don't know if you have thought that there is a limit to the endurance of water, and now water resources are in short supply! There are two main reasons for this situation: first, the lack of nature itself; Second, man-made destruction. Of course, we can't blame God for being unfair to us and giving us a planet short of water. On the contrary, we should thank God for creating a beautiful home for us.
However, it is in this emergency that we humans continue to waste and destroy water resources. Because a large amount of industrial wastewater is discharged into Lian and Rong rivers, the water quality of the two rivers is seriously polluted, and the water quality only reaches the third class standard, so it can neither be drunk nor used for irrigation. As an island county like South Australia, its water use depends entirely on "God's arrangement"-the rainwater collection area of all Shantang reservoirs, including flood diversion projects, only accounts for 3 1%, and it is still difficult for industrial and agricultural production and people's living water. It can be seen that it is urgent to properly handle the pollution and destruction of water resources. However, there is a serious shortage of water resources in the world today, and wars caused by water are increasing day by day. For example, of all the resources in the Middle East, water is the most likely to cause crisis, and water in the Middle East is more expensive than oil. Most countries in the Middle East are seriously short of water. The Middle East has suffered from drought for more than ten years and is facing a serious water crisis. The Little Jordan River has given birth to two major religions, which is the most hotly contested water source in the Middle East, and four wars in the Middle East have been related to this. The Jordan River provides two-thirds of the water for Lake Galilee, Israel's main water source. The Johnston agreement of 1955 stipulated the water quantity of all parties, but only Israel signed it, and Arab countries wanted to cut off the Jordan River in the 1960s. 1965, the Israeli army bombed the interception equipment in Syria. Both Arab countries and Israel take the destruction of competitive water resources as their primary strategic goal, and Israel has occupied the Golan Heights, the birthplace of the Jordan River. One of the difficulties in Syrian-Israeli negotiations is that Israel insists on occupying most of the water sources in the West Bank. At present, the water resources in Palestine are completely controlled by Israel, and the per capita water consumption is only three-quarters of that of Jewish settlers, but the cost is as high as twice. Pakistan had to over-extract groundwater, which made the water quality worse. The groundwater in Gaza has become too salty to be used. Since the violent conflict, Pakistan's water resources have been neglected, and the water shortage is more serious.
There is no comprehensive agreement on sharing water resources among the three major water systems in the Middle East, and disputes continue. The Nile flows through 10 countries, and the upper reaches are influenced by Egypt. Egypt built the Aswan Dam, which solved the water problem, but it caused dissatisfaction among upstream countries. Whenever there is a dispute, Sudan threatens to cut off water. Ethiopia signed an agreement with Sudan in 199 1 to extract 4 billion tons of river water every year. Egypt strongly opposes it. Turkey is rich in water resources, and the construction of South Water by Turkey to reduce the water flow to Syria and Iraq has been strongly opposed by both countries. Turkey and Israel have reached an agreement to transport the Manafort River to Israel by world ships, and Jordan and Syria are also considering buying water from the soil. Turkey hopes to play its role as a water power and promote cooperation and stability in the Middle East. Israel wants Turkey to increase its water supply to Syria. In exchange for Syria's concession to the border of Lake Gali, Turkey refused to get involved in the complicated Arab-Israeli dispute.
It can be seen that the shortage of water resources will be buffered for a period of time in order to use the right. It is not easy. The only way is to save water, and in this respect, Israel has done better. Two-thirds of Israel is desert, and there is no rain for seven months in a year. The per capita water resource is nearly 70 cubic meters, which is less than 1/4 in the Middle East, 3% in the world and 1/8 in China. However, it is in this barren and water-deficient land that Israel has built modern agriculture through scientific water use, which has amazed the world.
Agriculture is the foundation of Israel's founding. 1952, Israel spent 100 and 500 million dollars, and completed 10/45 km of "South-to-North Water Diversion Project". In the mid-1960s, the scientific water use method of drip irrigation was popularized, which promoted the rapid development of agricultural economy. The agricultural population in Israel has dropped from 60% to 3%, and a farmer can support 90 people, with a per capita GNP 1 80,000 USD, ranking first in the world 12. Israel cherishes water resources very much and regards water as its lifeline. Saving water is a systematic process, involving all aspects of society. Therefore, success has been achieved.
Water makes green grass greener.
Water makes flowers bloom.
Water makes trees tall and straight.
But you are getting haggard every day.
Aging every day.
Tears again and again.
If people do not cherish water resources, then the last drop of water in the world is people's tears.
