Thoughts about Lop Nur

History has proven that human beings’ blind arrogance has destroyed the ecological balance and repeatedly caused ecological disasters that destroyed human beings themselves. The causes that destroy the ecological balance can be divided into three categories: 1. Destroying the environment: Since the environment is one of the components of the ecosystem, its changes will affect the stability of the ecosystem. There are many examples of environmental damage that breaks the balance of the ecological environment, such as: the formation of eutrophication in lakes and swamps; the mercury poisoning incident in Japan; fluoride destroying the ozone layer; the deterioration of the ecological environment of the Aswan Dam; after the application of "666" and "DDT" The negative consequences; the "wet chamber effect" on the earth, etc. 2. Destruction of vegetation. Vegetation, mainly forest, is a lever for terrestrial ecological balance. Destruction of vegetation has caused the most ecological disasters on earth. For example, the black storm that occurred in the western United States in 1934 destroyed more than 45 million acres of cultivated land; in 1963, The great storm that occurred in the agricultural reclamation areas of the former Soviet Union destroyed more than 300 million acres of farmland; the ancient Babylonian civilization also perished due to the destruction of forests; the Thar Plain between India and Pakistan was reduced to a desert due to forest destruction. Covering an area of ??650,000 square kilometers; the deterioration of ecological conditions in the Yellow River Basin in China is due to the destruction of forest vegetation in the upper reaches. Today, the Yangtze River will become the second Yellow River; the deterioration of ecological conditions in the northeastern forest areas is mainly due to the destruction of forest vegetation in the southwest and unreasonable logging and over-logging of forests in the Northeast forest region. 3. Destruction of the food chain: Examples of destruction of the food chain and ecological balance include: excessive hunting of natural enemies of insect pests caused forest diseases and insect pests; India once hunted a large number of otters, which increased the number of diseased fish and reduced fish production; Australia, which has developed animal husbandry, became a problem due to cow dung covering the grassland. The example of dung beetles rescued by disasters is even more recent. Of course, several inducements often coexist in the biosphere.

China is a country prone to ecological disasters. The earliest and most profound ecological disasters experienced by China are soil erosion, land desertification, climate deterioration, flooding, and siltation of reservoirs and dams. In recent years, the pollution of our country's waters has increased: the mesh size has become smaller and there are fewer fish and shrimps. Scientists predict: "The ecological crisis will become the biggest crisis facing mankind in the 21st century." This tells people that with the development of industrialization and the increase in population pressure, humans must learn to live in harmony with nature.

When a person's body functions are out of balance, he will get sick or even die;

If the ecology of one place is out of balance, other places will also taste the bitter consequences;

The whole When the ecology is out of balance, the overall living environment of mankind will deteriorate...

People have gradually realized that human beings are not the masters of the earth. Wild animals, like people, are a link in the biological chain, and they are all part of the biological chain. Have the right to survive. Cruelty to wild animals is a disregard for life. Protecting wild animals is to protect our ecological environment and protect humans themselves. Therefore, caring for wild animals and promoting people's kindness reflect human beings' concern for their own survival and development in a deeper sense. While improving the situation of animals, they also improve human beings.

This is not only a conceptual issue, but also an inevitable requirement for social progress, reflecting the degree of civilization of a country. Because of this, in countries such as Germany, the United Kingdom, India, and the Philippines, not to mention the killing of wild animals, even if ordinary animals are emotionally abused, they will be prosecuted by law.

1. Why does the author emphasize that the left side of the word "Bo" in Lop Nur is three points of water?

p>

A moor is a lake, a lake is a lake, and a moor is a lake. "Lop Nur, the lost fairy lake" means that Lop Nur was once a lake with a lot of water, a very beautiful fairy lake. The author uses this to emphasize that this very beautiful fairy lake has now disappeared and turned into a desert.

2. Why is Lop Nur said to have "become a terrifying place"?

Today's Lop Nur: It is a place full of mystery. Chinese scientist Peng Jiamu and explorer Yu Chunshun were there successively Missing, killed; there is the restricted area of ??life, it is a mysterious and terrifying endless Gobi Desert, there is not a single grass, not a stream, the temperature in summer is as high as 70°, there is not a bird in the sky, and no bird dares to time travel.

3. A large amount of data is cited in the article. What is the author’s purpose of citing these data?

The author’s purpose of citing these data is to let us understand Lop Nur through detailed information. The past and present have made us realize the consequences of human blindness and greed. The full text is full of a strong sense of urgency and regret, which is enlightening and shocking.

4. The author’s intention in writing about Populus euphratica forest

Characteristics of Populus euphratica forest: beautiful and immortal for thousands of years.

It has the functions of sand prevention guard, green Great Wall, and creation of oasis. Without it, the desert will expand and the sand will advance and people will retreat.

Author's intention:

It is a tragedy that the Populus euphratica forest, which plays such an important role and has such tenacious vitality, was wiped out. This is not only the tragedy of Populus euphratica, but also the tragedy of mankind itself. The tragedy is that human beings have personally destroyed the environment they rely on for survival. It can be seen how serious human beings have destroyed the ecological environment. Because of this, the author is deeply worried, which highlights the center of the article.

The disappearance of Lop Nur has caused man-made destruction of the ecological environment, rapid deterioration, and the expansion of the desert.

Similar tragedies include: the water level of Qinghai Lake has dropped, and the land has extended into the lake; the water area of ??Crescent Moon Spring has shrunk and is on the verge of drying up.

The underlying reason for the disappearance of Lop Nur is human factors. The specific manifestations are two diversions and four "blindnesses". Blindness means short-sightedness, eager for quick success, only pursuing immediate interests, regardless of long-term interests, and having no concept of sustainable development in the mind; blindness means narrow-sightedness, only pursuing the interests of the local area, regardless of the overall interests; blindness means not understanding the laws of nature and ecology Balance, do not understand that if the water is drained upstream, the river downstream will dry up, and the surrounding ecological environment will seriously deteriorate and even become desertified.

(Only seeking immediate benefits, regardless of long-term interests, and no concept of sustainable development)

There are two reasons for its disappearance:

① 20th century In the 1990s, the Nationalist Government changed the course of the Tarim River, causing drought in the lower reaches of the Tarim River and reducing the amount of water injected into Lop Nur. ② In the past 30 years, the population of the Tarim River has surged, blindly increasing water use for cultivated land, blindly building reservoirs to carry water, blindly digging embankments to divert water, and blindly building pumps. Station pumping water caused the rivers downstream of Tarim to dry up, Lop Nur to lose water, and the ecological environment was completely destroyed.

Enlightenment:

The earth is our only home. Home is a warm word, the habitat of the soul and the source of happiness. If our home is gone, what will we have left? Please look at our own hands, are they creating or destroying? Please look at our own eyes, are they filled with eager hope, or are they helpless and confused? We have reason to believe: the sky will become bluer, the trees will become greener, and the water will become clearer... Students: Let us start from now on, starting from ourselves, maintaining ecological balance, protecting the environment, and protecting ourselves. own home. I sincerely hope that the mountains will always be green, the water will always flow, and the beauty will last forever.
