Has humanity destroyed resources? How did humans destroy?

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.

Examples: 1. Destruction of vegetation: Vegetation with forests as the main body is the lever of terrestrial ecological balance, and the ecological disasters caused by unreasonable and excessive logging of vegetation on the earth are the most.

For example, the Black Storm that occurred in the western United States in 1934 destroyed more than 4,500 acres of arable land; The ancient Babylonian civilization perished; The Thar Plain, between India and Pakistan, has been reduced to a desert with an area of 650,000 square kilometers due to deforestation.

2. Destruction of the food chain: forest diseases and pests caused by over-hunting and killing natural enemies; In India, the killing of otters in large quantities has increased the number of diseased fish and reduced fish production; Australia has a well-developed pastoral industry.

3. Greenhouse effect and ozone layer depletion: the content of liquid carbon dioxide in the atmosphere increases, and the fuel contains various complex components, which produce various harmful substances after combustion, even if the fuel without impurities reaches complete combustion, it produces water and carbon dioxide, and destroys the balance of carbon dioxide in nature.

4. Acid rain: With the increase of industrialization and energy consumption, acidic emissions are increasing, and they enter the air and form acid rain through a series of actions.

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...
