It's resource destruction. Human beings excessively consume various mineral resources. According to traditional consumption calculations, the world's oil is only enough to last for 50 years, and coal and natural gas are only enough to be exploited for 200-300 years.
It's ecological destruction. In the 50 years of the last century, half of the world's forest resources have been lost. According to the Food and Agriculture Organization of the United Nations, 2,000 square meters of forest are destroyed every minute on the planet.
It is the desertification of the land. The world's desertified land has reached 36 million square kilometers, almost the land of China, the United States and Russia combined.
It is the decrease of species. On average, one species is wiped out every day on Earth, and it is expected that 6,000 plant species will be wiped out on Earth in the next 30-40 years.
It is environmental degradation. Environmental degradation is a prominent problem caused by industrial civilization and unsustainable development for human beings. The London smog incident of 1952, which killed 4,000 people in five days.
Top 10 global environmental issues.
1. Climate warming.
2. Ozone layer depletion.
3. Biodiversity is decreasing.
4. Acid rain spreads.
5. Forests are declining.
6. Land desertification.
7. Air pollution.
8. Water pollution.
9. Marine pollution.
10. Solid waste pollution.
Second, the state of the environment in our country.
1. Air pollution is soot-type pollution, with dust and acid rain being the most harmful, and the degree of pollution is intensifying.
2. Acid rain is mainly distributed in the south of the Yangtze River, the east of the Qinghai-Tibet Plateau and the Sichuan Basin. Acid rain is the most polluted region in central China.
3. The waters of rivers, lakes and reservoirs are generally polluted to varying degrees, except for some inland rivers and large reservoirs, the pollution has become an aggravating trend, and the water pollution near industrially developed cities and towns is particularly prominent.
4. Among the seven major river systems (Pearl River, Yangtze River, Yellow River, Huai River, Hailuan River, Liao River, and Songhua River), the Yellow River Basin, Songhua River, and Liaohe River Basin are seriously polluted.
5. Total phosphorus and total nitrogen pollution in large freshwater lakes are widespread, and eutrophication is serious.
6. The Bohai Sea and the East China Sea are heavily polluted in the four major sea areas, while the South China Sea is lighter.
7. The deterioration of the ecological environment of fishery waters has not fundamentally changed, and is showing an aggravating trend.
8. Urban environmental pollution is aggravating.
9. Urban ground water pollution is generally serious and shows a deteriorating trend. The vast majority of rivers are polluted to varying degrees.
10. 2 3 rivers and more than 10 million hectares of farmland across the country are polluted.
-
1. Excessive deforestation.
2. Excessive waste of groundwater and fresh water.
3. Overexploitation of various mineral resources.
4. Mass hunting of various animals (especially marine fish is the most serious, in order to eat and sell for money) 5. Mass hunting of rare animals (in order to enjoy the feeling of shooting, collect a certain part of the animal's body, or sell it for money. In fact, after human beings became the masters of the world, a large number of wild animals and plants have become extinct. The most famous dodo, there are many creatures whose names you have never heard of, such as:
Silver-spotted black pigeons, Ryukyu kingfishers, etc. Because of the existence of human beings, the earth has begun the sixth mass extinction. )
6. Excessive waste of oil.
7. Pollution of the oceans, especially those caused by war. Like the Gulf War, it caused the death of a large number of birds, fish, corals and other marine life.
8. The damage to the environment caused by war.
9. The harm of high-tech products such as automobiles, air conditioners, refrigerators and other high-tech products to the earth.
10. The pollution of all kinds of domestic garbage to the earth, especially plastics, is the most serious.
11. The increase in the scope of human activities has affected some animals and plants.
12. The impact of population growth on the planet. (There are now more than 7 billion people in the world, and the food, drinking water, and warm clothing consumed by each person every day are huge.) Sooner or later, the earth will not be able to withstand such consumption. )
-
Since the beginning of human industrialization, global fishery resources have decreased by 90 percent; 1 3 of amphibians, 1 5 of mammals and 1 4 of coniferous species are endangered; Nature's ability to regulate climate, air and water has declined dramatically; The impact of natural disasters on humanity is increasing.
-
Various activities will be carried out, such as mining, large-scale civil engineering, nuclear experiments, etc.
-
For example, humans cut down trees, throw garbage into the sea, and mine minerals in large quantities.
-
Cutting down trees and polluting the environment.
-
Probably, because the damage to the earth is too serious now, and at the same time, the earth's ability to withstand it is also limited, so it may go to extinction.
-
Of course, it will go to extinction, and now the earth is already undergoing various changes every day, with rising temperatures, torrential rains, and sandstorms.
-
Yes, if humanity continues to do this, then one day humanity will surely go to extinction, and it will also make the earth disappear.
-
The damage that humans have done to the planet:
1. The use of chemical and nayana energy sources will change the composition of the atmosphere and cause climate change;
2. The use of chemicals to pollute water sources;
3. Excessive felling of trees, construction of houses, and land reclamation, resulting in desertification in some areas;
5. Population expansion, making a large number of species extinct;
6. Create pollution, making many places unsuitable for biological growth. Let it be held.

The world's weirdest well - Kola ultra-deep hole.
The Kola Ultra Deep Well (Russian: is a scientific drilling carried out by the former Soviet Union in 1970 in the area of the Kola Peninsula near the Norwegian border, the deepest hole of which SG-3 reached 12,263 meters in 1989, and to date, this hole is still the deepest man-made hole in the earth. However, its well depth records were broken in 2008 and 2011 by the Ashosin well in Qatar (12,289 m) and the Russian Odotu op-11 well in Sakhalin (12,345 m), which currently ranks third in the world. >>>More

There are various classifications of environmental pollution: >>>More
Wanton emission of polluting gases, endless exploitation of non-renewable resources, no effective way to organize, waste of water resources, etc., no awareness of conservation and protection. And so on and so forth.
