Examples of people destroying natural resources at will:
1. Acid rain: Acid rain is acidic precipitation with a pH value less than that caused by acidic pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) in the air. In areas affected by acid rain, a series of serious environmental problems have occurred, such as acidification of soil and lakes, destruction of vegetation and ecosystems, and corrosion of building materials, metal structures and cultural relics.
2. Toxic chemical pollution: There are about 780,000 kinds of chemicals in the market that are polluted by toxic chemicals. There are about 10,000 kinds of hazards to human health and the ecological environment.
Among them, there are more than 500 kinds of carcinogenic, teratogenic and mutagenic effects. With the development of industrial and agricultural production, 1,000 2,000 new chemicals are now introduced to the market every year. Due to the widespread use of chemicals, the atmosphere, water, soil and even organisms around the world have been polluted and poisoned to varying degrees, even the penguins of Antarctica have not been spared;
3. Global warmingGlobal warming: Global warmingGlobal warming refers to the fact that the main reason for global warming caused by the increase in global temperature is that human beings have used a large number of fossil fuels (such as coal, oil, etc.) in the past century, emitting a large amount of CO2 and other greenhouse gases;
4. Sharp decline in forests
Forests are an important part of the ecosystems on which humans depend. Once 7.6 billion hectares of forests on Earth, it fell to 5.5 billion hectares this century and 2.8 billion hectares by 1976.
The dangers of the indiscriminate destruction of natural resources are:
1. Excessive groundwater pumping leads to ground subsidence;
2. Overgrazing leads to desertification;
3. Cutting down trees will also lead to desertification;
4. Overfishing will lead to a sharp decline in the number of fish;
5. Crazy hunting of wild animals will make animals extinct;
6. Emissions of harmful gases have warmed the global climate, melting icebergs at the poles, and rising sea levels, exposing coastal cities and countries to the danger of being submerged.
-
1.Logging, destruction of forests.
2.Overgrazing, destruction of playgrounds.
3.Sewage discharge, polluting rivers.
4.Emissions of greenhouse gases.
5.Hunting, making species extinct.
6.Destruction of the ozone layer.
7.Flood irrigation makes the soil salinized.
8.Use biochemical ** to pollute the environment.
9.Produce genetic organisms that threaten the ecological balance.
10.Groundwater is pumped to bring the surface down.

Shocking environmental pollution can be seen everywhere: dark skies, polluted air, cross-flowing sewage, and ...... garbage sieges, even in the ice and snow of the Antarctic penguins, DDT and other pesticide residues have been found, Mount Everest is everywhere? The blue sky and clear water have become a childhood memory and unattainable dream for many people.
The Antarctic ozone hole is caused by excessive use of freon in the past and its emission into the air, which will irradiate a large amount of ultraviolet rays on the earth, increase the incidence of cancer, and increase the temperature of the earth; Red tide occurs in many waters because domestic and industrial wastewater enters the waters, which are rich in nitrogen and phosphorus, which causes eutrophication, which will lead to the death of fish and shrimp, and will also damage people's health through bioaccumulation; The destruction of virgin forests in the United States is man-made, and many trees have been cut down. As a result, many animals have been displaced, and some species have even perished.
Lop Nur, the Disappearing Fairy Lake", that is, Lop Nur was originally a very beautiful lake, but now it has disappeared and become a desert. This is a tragedy of man-made destruction of the ecological environment. With a strong voice, this reportage warns the people of the world to establish the awareness of environmental protection among the whole people and do a good job in ecological protection.
Cutting down trees. Digging river sand.
The cause of animal killing and environmental pollution is mainly caused by human factors. Usually people in production, life emissions of a large number of "three.
"Waste" and sudden accidents in some industrial and living facilities, as well as untreated waste in hospitals, can cause environmental pollution, and in serious cases, it can cause harm. In wartime, due to the massive use of various ** to kill residents and damage residential areas, it can cause environmental pollution and destruction.
For example, air pollution in cities causes air pollution, and people's morbidity increases. Water pollution deteriorates the quality of the water environment, and the quality of drinking water sources generally declines, threatening people's health, causing premature birth or malformation of the fetus. Serious pollution incidents not only cause health problems, but also social problems. With the intensification of pollution and the improvement of people's environmental awareness, the disputes and conflicts among people caused by pollution are increasing year by year.
Protecting the environment is everyone's responsibility.
You and I work together to build a home together.
Changes in ecological and environmental protection: air quality, water environmental quality, soil environmental quality. >>>More
In recent years, the degradation of wetland ecosystems has been caused by irrational use such as wetland reclamation, overuse of biological resources, environmental pollution of wetlands, overuse of wetland water resources, construction of water conservancy projects in large river basins, sediment sedimentation, coastal erosion and destruction, and blind development of urban construction and tourism. Wetlands have been severely damaged in recent centuries. Although the drying up of wetlands is an inevitable consequence of natural processes, the rapid elimination of many wetlands is closely related to unreasonable human economic activities. >>>More
