Data on the destruction of natural resources in the world, what are the natural resources destroyed

Natural resources are divided into: renewable resources and non-renewable resources. Mineral resources are non-renewable resources, and land, water, biological and other resources are renewable resources.

Due to people's predatory exploitation and utilization of resources, natural resources have been damaged to varying degrees, especially water resources.

There are reports that it says"According to the survey of 798 cities and towns in 979, the daily sewage discharge of the country is 2.58 million tons, of which 819 are occupied by industrial wastewater and 854 cities and towns are occupied by domestic sewage, and the daily discharge reaches 100 million tons. Among them, 100 million tons of industrial wastewater have been agreed.

Most of this wastewater is discharged directly without treatment, polluting rivers, lakes and seas. In addition, there is an indisputable fact in front of every Shanghainese. The Huangpu River, the mother river of Shanghai, was a river with clear water quality and a group of fish and shrimp before the mid-50s (1958), the water quality began to be polluted in 1962, and in 1963 it began to appear for a period of 22 days of black and smelly period, and in 1988 it rose to 29 days, accounting for about 2 3 of the year.

Water pollution and deterioration of water quality have brought serious harm to human health, human life and production. Water is an important substance for human survival, clean people can bring people verdant flowers and trees, birds singing and flowers, quiet and comfortable, beautiful and picturesque beautiful environment, to bring people peace, pleasure and peace. But today's polluted water is causing suffering, terror and catastrophe to people.

In order to make life better, let the beautiful mountains and rivers stay in the world forever, and let the clear water flow continuously, people have become more and more aware of the importance of preventing water pollution. Sowing green is sowing hope for garbage surplus and environmental problems, from drinking pure water to thinking of garbage and recycling, comprehensive utilization of garbage, and resource comprehensive utilization of science in the bathroom.

The reasons for the destruction of the earth's natural resources are: (1) the extent of human exploitation of resources is too large, exceeding the ability of resources to regenerate; (2) human activities destroy the environment in which resources are formed;

The population is growing and requires a lot of natural resources; Overexploitation of natural resources.

Ozone layer depletion, desertification, air pollution, water pollution, global desertification, particularly severe.

Felling trees and discharging sewage.

For the sake of their own selfish interests, human beings have arbitrarily destroyed the earth, causing harm to the earth, people have cut down trees indiscriminately, and discharged sewage into rivers, lakes and seas...

Is it? Do you know that the sea level of the Green Lake is dropping? Did you know that Crescent Spring is on the verge of drying up?

The same tragedy continues, what other examples of ecological deterioration do you know? There are 350 species of birds in Heilongjiang Province. In recent years, due to the rapid development of agriculture and fisheries, and the destruction of the natural environment, the habitat of birds and the environment of breeding grounds have deteriorated and shrunk.

At present, 68 species of birds such as falcons, cranes, storks and grouses are endangered, including whooper swans, white-headed cranes, black storks, Chinese mergansers, black-billed grouse, great bustards, etc. Known as the "Pearl of Treasure Island", the Songtao Reservoir is responsible for the irrigation of more than 2 million acres of farmland, as well as the flood control safety of nearly 2 million people and 560,000 acres of farmland in the lower reaches of the Nandu River, and also provides 100 million tons of industrial and domestic water to Yangpu, Laocheng, Haikou and other places every year. However, it is worrying that the ecological environment of the Songtao Reservoir is being destroyed, and illegal deforestation and mining incidents have been repeated in recent years.

Standing on the pier of the reservoir and looking around, the scene in front of you is shocking. Some of the originally densely forested hills and slopes around the reservoir have been shaved with unsightly baldness and scars. At present, China's desertified land has reached more than 10,000 square kilometers; The cultivated land and homes of 471 counties and nearly 400 million people in 18 provinces and autonomous regions of the country are threatened by desertification to varying degrees, and desertification is still increasing at a rate of more than 10,000 square kilometers per year.

Among the seven major river systems, the water quality has no use value at all has exceeded 40. More than 400 of the country's 668 cities are in a state of water shortage. Many of them are caused by water pollution.

For example, Ningbo City, Zhejiang Province, is located at the intersection of the Yongjiang River, Yao River and Fenghua River, but due to water pollution, it is necessary to rely on water trucks to run day and night when there is the most water shortage, and transport the water from the rural river into various enterprises in the city. China's average industrial added value of 10,000 yuan consumes 330 cubic meters of water and produces 230 cubic meters of sewage; For every 100 million yuan of GDP created, 10,000 tons of wastewater will be discharged. There is also a large amount of domestic sewage.

More than 80 of them are discharged into rivers without treatment, and within 10 years, China will have no water to use. 1 3 of the country's urban population breathes heavily polluted air, and 1 3 of the country's land is eroded by acid rain. In economically developed Zhejiang Province, the acid rain coverage rate has reached 100.

The frequency of acid rain is 11 in Shanghai and 12 in Jiangsu. In central China and some southern cities, such as Yibin, Huaihua, Shaoxing, Zunyi, Ningbo, Wenzhou, etc., the frequency of acid rain exceeds 90. In China, the maximum allowable sulfur dioxide emissions for the basic elimination of acid rain pollution are 12 million 14 million tons.

In 2003, the country's sulfur dioxide emissions reached 10,000 tons, an increase of 12 over 2002, of which industrial emissions increased. At the current rate of economic development. By 2020, the country's thermal power plants alone will emit more than 21 million tons of sulfur dioxide, and all emissions will exceed the atmospheric environmental capacity by more than 1 times, which will be a serious disaster for the ecological environment and people's health.

Water is the source of life, and water seems to be everywhere. However, the shortage of drinking water threatens the survival of humanity. At present, the world's annual water consumption has reached 7 trillion cubic meters, coupled with the discharge of industrial wastewater, the abuse of chemical fertilizers, the arbitrary dumping of garbage, and the sharp increase of domestic sewage, turning rivers into gutters and lakes into sewage lands; Deforestation has caused a large amount of water to evaporate and run, and drinking water is decreasing dramatically.

The water shortage has sounded the alarm bell for mankind. According to the GEMS water quality monitoring project, about 10 of the world's monitored rivers are polluted, with biochemical oxygen demand (BOD) values exceeding 6.5 milligrams of litres, nitrogen and phosphorus in the water being polluted, and the average phosphorus content of polluted rivers is 2.5 times the average of unpolluted rivers. According to United Nations statistics, there are currently more than 100 countries and regions in the world that have a shortage of domestic water, of which 43 countries are suffering from severe water shortages, endangering the survival of 2 billion people, mainly in Africa and the Middle East.

Many scientists predict that water will become the most scarce resource in the 21st century. As one hopes, don't let human tears be the last drop of water on earth.

Reduced forest area.

Forests are known as the "lungs of the earth" and "nature's general dispatch room", which has a major regulatory function for the environment. Due to extensive imports from developed countries and land reclamation, logging and grazing in developing countries, the forest area has been greatly reduced. Greenpeace estimates that 80% of the world's primary forests have been destroyed in 100 years.

According to the latest report of the Food and Agriculture Organization of the United Nations, if the total land area is calculated, the earth's forest cover is only 26 6. Deforestation leads to soil erosion, frequent flooding, global warming, disappearance of species, etc. Human beings, who blindly demand from the earth, have pushed the living earth to a very dangerous situation.

People have always thought that the sea, land and air on the earth are endless, so they have never worried about sending tens of millions of tons of exhaust gases to the sky and dumping hundreds of millions of tons of garbage into the ocean. Everyone thinks that the world is so big, what is this waste? We are wrong, in fact, although the earth is large (more than 6,300 kilometers in radius), but living things can only live in the range of 8 kilometers above sea level to 11 kilometers under the sea, and 95% of the living things can only live in the middle of about 3 kilometers.

Marine pollution: mainly leakage from oil tankers and oil wells, pesticides and fertilizers used in farmland, sewage discharged from factories, and acidic solutions flowing from mines; They pollute most of the ocean's lakes and cause damage not only to marine life, but also to birds and humans who can be poisoned by eating them.

Land pollution: garbage cleaning has become an important problem in major cities, and many of the tens of millions of tons of garbage every day cannot be incinerated or corrupted, such as plastic, rubber, glass, aluminum and other waste, which has become the number one enemy of urban sanitation.

Air pollution: This is the most direct and serious, mainly from the carbon monoxide and hydrogen sulfide emitted by factories, cars, power plants, etc., and people are exposed to these dirty air every day and contract respiratory or visual diseases. If we continue to ignore the warnings of the experts, we will surely fall to the point where there is no pure land to live in in the future.

Cutting down trees, rafts, forests, soil erosion, and mining of underground ore resources.
