What natural disasters will be caused by the felling of trees and the destruction of forests?

Desertification, mudslides, landslides, floods, droughts, typhoons.

increase in desert area; Soil erosion.

will cause, dust storms, exacerbate global warming.

Forests are the largest distribution area on the earth, the most abundant ecosystem, known as the lungs of the earth, maintain the global ecosystem balance, have a variety of functions such as maintaining water and soil, purifying the air, regulating temperature, and improving climate protection species, and are an important guarantee for maintaining the ecological balance and security of the earth. However, if the forest area is reduced on a large scale, it will bring unimaginable disasters to human beings, will reduce air quality, and after soil erosion increases, it will cause global warming, make the temperature of the whole earth abnormal, cause various extreme weather, and make drought and flood unbalanced, and will cause a series of very serious consequences. Some experts have predicted that if there were no forests on the earth, human beings would never live for more than a year.

Now with the continuous development of the economy, the rapid development of various countries, the continuous indiscriminate felling of trees, indiscriminate sewage discharge, caused very serious environmental pollution, coupled with the occurrence of various disasters, land desertification also makes a lot of vegetation on the earth less and less, so that some animals and plants live in the environment is also more and more reduced, but also make the quality of the air worse and worse, so that the air we breathe is mixed with some harmful substances, such as sulfur dioxide, These will imperceptibly endanger everyone's health. And according to the data, the current rate of global deforestation and forest degradation is alarming, so measures must be taken to protect forest biodiversity.

If you want to protect the forest, in fact, you can start from our daily life, usually save water resources as much as possible, but also refuse some white garbage, as far as possible do not use disposable lunch boxes, chopsticks, plastic bags, etc., as long as it can reduce the amount of garbage, and can also reduce the production of plastic products, save a lot of raw materials, including some hydropower resources, usually in life should also cherish their own paper, for the use of paper, books and newspapers should be classified, cherish paper is also cherish the forest.

Finally, in the face of the large-scale reduction of forests, what we can do is to make timely changes, give the earth a green mountain and clear water, and make efforts for the long-term sustainable development of the earth.

This will expose humanity to many disasters, such as heavy rainstorms, tornadoes, sandstorms, mudslides, and so on. This is not conducive to ensuring the safety of human life, nor is it conducive to providing a livelihood guarantee for human beings. Therefore, this also tells us a truth, do not cut down trees at will in ordinary life, and must know how to protect the environment.

It will affect the ecological environment of human beings, and there will also be serious environmental pollution, which is not conducive to the development of the natural environment, will lead to the continuous reduction of organisms, and will also affect the climate, which may lead to global warming.

Changes in the climate, a decrease in oxygen, serious soil erosion, air pollution, and an increase in solar radiation will bring great disasters to human beings.

Dust storms, mudslides, landslides. 1. The roots of trees stabilize the sand and soil to retain water, and the trees are cut down and the soil is eroded; 2. Trees themselves can prevent wind and fix sand, provide food for other organisms, trees are cut down, the bottom of the food chain is broken, and the ecology deteriorates.

National Standards:

1. Yellow warning for sandstorms.

Criteria: Dust storms are likely to occur within 12 hours (visibility is less than 1000 meters), or dust storms have already occurred and may occur and may continue.

2. Orange warning for sandstorms.

Criteria: Severe sandstorms are likely to occur within 6 hours (visibility is less than 500 meters), or sandstorms have already occurred and may occur and may continue.

3. Red warning for sandstorms.

Criteria: Very strong sandstorms (visibility less than 50 meters) are likely within 6 hours, or sandstorms have already occurred and may continue to occur.

The destruction of forests can cause hazards such as mudslides, urban desertification, sandstorms, flooding, and the reduction of the ozone layer.

nbsp;Whether it is a human or an animal, living on the earth needs to breathe oxygen, we know that oxygen is the product of photosynthesis by green plants, if we destroy the forest on a large scale in addition to the reduction of oxygen production, what natural disasters will it bring? Let's find out!

Details:

Forests are the umbrella of human beings, it has a rich species, complex structure, and a variety of functions. It is known as the cradle of human culture, the decoration and beautifier of nature, the resource of life, the habitat of wild animals and plants, the golden treasure house, the green treasure house, the natural oxygen manufacturing plant, the green bank, the natural regulator, the originator of coal, the natural water storage tank, the windproof Great Wall, the natural vacuum cleaner, the lungs of the city, the natural monitor, the natural epidemic prevention officer, the natural soundproof wall, the natural reservoir, the lungs of the earth, and the natural air conditioner.

The destruction of forests may lead to global climate imbalance, ecological environment degradation, frequent natural disasters, and sharp decline in biodiversity. Among the natural disasters are mudslides, urban desertification, sandstorms, floods, ozone layer reduction, <>

Destroying forests, making them unable to conserve water, and prone to flooding; It makes the forest unable to maintain water and soil, which is easy to cause landslides and mudslides; It is the inability of forests to conserve water, which leads to desertification of the land, followed by sandstorms; Reducing the production of oxygen by forests, resulting in the destruction of the ozone layer.

Felling of trees does not cause direct natural disasters and indirect harm. Barren land, soil erosion, expansion of desert area, reduction of human living space, poor living environment, sandstorms, desertification, deterioration of air quality, reduction or even disappearance of animal and plant species, cutting down trees makes small birds lose their habitat and lose some food**, without the protection of leaves, birds are more likely to be captured by natural predators, causing harm.

Desertification will lack the supply of oxygen and a barrier against wind and sand fixation. The ecological environment is occupied, and the laws of the biosphere are destroyed. The temperature rises, creating irregular changes in the climate.

The debris of the felled trees is burned, which pollutes the environment. The birds have lost their homes, and the earth has no flowers.

Unscientific or over-harvesting can cause meteorological disasters such as soil erosion and storm disasters.

Indiscriminate deforestation will destroy the biodiversity of forests, and many organisms will lose their original habitats and become endangered.

2. Indiscriminate felling will homogenize local species and reduce the ability to resist pests and diseases, for example, where there are more plantations, pine caterpillars are prevalent.

3. Indiscriminate deforestation will reduce the ecological regulation function of the forest and reduce the air purification capacity of the forest.

4. Forests play an important role in maintaining soil and water, and indiscriminate deforestation will exacerbate soil erosion. Desertification of land, soil erosion, sandstorms, tornadoes and other natural disasters.

The forest coverage rate of our country is about 20%, lower than most countries in the world, in the 139th place, China's per capita value is less than 1 4 in the world, due to a long period of excessive logging, many famous forest resources in our country are on the verge of depletion. For example, in Changbai Mountain, Daxing'an Mountains, and Xiaoxing'an Mountains, forest resources have been exhausted, and some places have become barren mountains and bald mountains.

The reduction of forest resources is a serious harm to human beings, which can exacerbate soil erosion and cause soil erosion, which not only changes the ecological environment in the upper reaches of the river basin, but also exacerbates the amount of sediment in the river, raises the river bed and increases flooding, for example, the Yangtze River flood in 1998 is closely related to deforestation in the upper reaches.

Extended Materials. According to the Food and Agriculture Organization of the United Nations, 12 million hectares of forest are lost every year, or an average of 20 hectares of forest are wiped out every minute. The world's deforestation is in developing countries, where poverty has forced them to trade valuable forest resources for foreign exchange.

1. Penalties. Those who illegally or indiscriminately cut down forests or other trees in national nature reserves shall be given heavier punishments.

2. Criteria for filing a case.

According to the provisions of the "Standards for the Jurisdiction and Case Filing of Criminal Cases of Forest and Terrestrial Wild Animals by the State Forestry Administration and the Ministry of Public Security", the starting point for filing a case of indiscriminate felling of forests or other forest trees is 10 to 20 cubic meters or 500 to 1,000 young trees;

Indiscriminate felling of more than 50 cubic meters of trees or more than 2,500 young trees is a major case; Indiscriminate felling of more than 100 cubic meters of forest or more than 5,000 young trees is a particularly serious case.

Landslides are a natural disaster that is prone to deforestation due to deforestation. When there is indiscriminate deforestation, the function of the forest to retain water and soil is weakened. A large part of the soil and water is prone to mudslides or landslides when it rains heavily or rains.

There are also fewer forests and are prone to dry weather.

Indiscriminate deforestation destroys the natural environment and causes soil erosion and air pollution.

Deforestation and deforestation will lead to natural disasters such as soil erosion, droughts, floods and mudslides.

1 Soil erosion After deforestation, the land cannot withstand the wind and rain. On sunny days, the decomposition of organic matter into soluble mineral elements accelerates due to the increase of ground temperature due to sun exposure. On rainy days, the rainwater directly washes the measurement, bringing the fertile topsoil and mineral elements into the river. It is estimated that more than 5 billion tons of soil are washed into rivers in Suiqing every year.

2 Quicksand siltation clogs reservoirs The Yellow River has the highest sediment content in the world, and when the flood comes, water and sand account for half each. Due to the siltation of sediment, the riverbed in some places in the lower reaches of the Yellow River is 12 meters higher than the land outside the embankment, and even higher than the city wall of Kaifeng City, which seriously threatens the safety of people's lives and property.

3. Environmental deterioration and frequent disasters.

If the forest cover in an area is higher than 30 and evenly distributed, it can be relatively effective in regulating the climate and reducing natural disasters. China's forest coverage rate is only 12, and the distribution is not even, which belongs to the Shaolin country. At present, the world's forests are disappearing at a rate of 18 million 20 million hectares per year, and the world's forest area has halved between 1950 and 1980.

The destruction of forests can have a range of serious consequences.

The geological epidermis is seriously problematic, the climate is warming and becoming worse, the living environment is deteriorating, the number of animal species is decreasing, the number of cherished plants is decreasing, and the ability of pollution control and nature to purify air quality is seriously reduced, and so on.
