What are the harms to the human living environment caused by the massive destruction of forest resou

Great harm, one day people will be in vain disaster...

Forest is an important natural resource, and human relations are very close, its contribution to human beings is diverse, can provide a variety of wood for human beings, however, China's forest resources are still decreasing, the following to share with you some of the role of forests, call on everyone to protect the forest from destruction.

1.Protect water sources. On the one hand, forests have the effect of preventing soil erosion and protecting water and soil; On the other hand, it has the function of preserving rainwater, and some people liken the forest to a "green reservoir".

2.Improving our living environment. Forests absorb carbon dioxide and release oxygen.

The oxygen emitted by forests is the most important oxygen we need as humans and animals, and one hectare of forest land can absorb 1,000 kilograms of carbon dioxide and release 730 kilograms of oxygen per day, which is of great significance for keeping the air fresh.

3.It is forests that play an important role in the prevention and control of environmental pollution. Forests absorb not only carbon dioxide, but also other toxic and harmful gases and air pollution.

In the process of industrial development, a large number of harmful gases are continuously emitted, such as sulfur dioxide, hydrogen fluoride, nitrogen oxides, etc., which pollute the environment. Forests can absorb all kinds of harmful gases in the low concentration range, so that the polluted air can be purified. In addition, some plants are sensitive to air pollution and can be used to monitor air pollution.

Forests reduce noise. Urban noise pollution is serious, and trees can reduce this harmful noise through the micro-vibration of their branches and leaves.

4.Forests are a great place to conserve wildlife. Forests are a good habitat for many wildlife, and valuable wildlife resources are inseparable from forests, without which they cannot survive.

5.Forests regulate the climate. Forests have tremendous transpiration. The average tree transpires 2,000 litres of water in a summer. As a result, the air humidity in woodlands is 15 to 25% higher than in woodlands, and precipitation is increased.

Afforestation is not only of great significance for the survival of human beings, but also has huge economic benefits for human production and life.

It can protect the environment, but it can also purify our air, and of course it can also produce a lot of oxygen for us, so that our environment will not continue to be bad, and human beings can live forever. It is also because of these functions of forests that human beings need to protect them.

It can maintain the ecological balance, and then it can provide people with a space to live on, it can also protect water resources, prevent soil erosion, prevent wind and sand fixation, regulate the climate, and there will be no particularly serious extreme weather, which can extend the living life of the earth.

The function of forests is to purify the air, protect animals and plants, and protect the environment in which humans live. It also allows green plants to grow taller. The reason why we want to protect forests is because they can make our environment better, it can also make people aware of protecting forests, and it can also protect our vegetation from destruction.

It also makes the air fresher.

I think that forests can protect the whole home, they can protect the whole earth, they can protect all people, they can protect all animals, and if it's very good, they can make the earth very beautiful, but I think the reason why humans want to protect forests from destruction is because forests are important to people.

Deforestation has a greater or lesser impact on the atmosphere, hydrosphere, biosphere and lithosphere

The main effects of forest destruction are:

1. The impact on the lithosphere, the large-scale destruction of forests will affect the soil, which will cause soil erosion, and then cause losses to human production activities.

2. The impact on the hydrosphere, deforestation has a certain impact on the inland water cycle, and the transpiration of vegetation in the inland water cycle is also one of the precipitation levels.

3. The destruction of forests will have an impact on the biosphere, threatening the survival of organisms that use forests as habitats, thus breaking the food chain. From the perspective of human survival, serious destruction of forests will have a certain impact on the sustainable development of human society.

4. The impact on the atmosphere, plants can reduce carbon dioxide in the air to a certain extent, and a large number of destruction of forests also affects the circulation of this atmosphere.

Soil erosion is intensifying. After the destruction of vegetation, the ability of rainfall to wash the soil is enhanced, and soil erosion is intensified. One is soil degradation, such as grassland degradation into desert; The second is to bring environmental pollution problems, such as eutrophication of water bodies.

Ecosystems are destroyed. Vegetation plays an important role in the ecosystem and is a habitat for animals, insects, etc. Biodiversity is also destroyed when vegetation is destroyed.

Human destruction has caused a variety of hazards to the earth's forest resources, including the following:

1.Deforestation and deforestation: Large-scale deforestation and destruction for timber, farmland, pasture and urban development. This has led to the reduction and fragmentation of forest resources, undermining the integrity and stability of forest ecosystems.

2.Biodiversity loss: Forests are one of the richest biodiversity habitats on Earth.

The destruction of forests leads to the loss of diversity and the extinction of species. Many endangered species, including animals, plants, and microorganisms, are directly threatened by deforestation.

3.Climate change: Forests play an important role in the global carbon cycle and climate regulation.

By absorbing carbon dioxide and releasing oxygen, forest vegetation has an important impact on mitigating climate change and greenhouse gas emissions. However, deforestation has led to the release of large amounts of carbon dioxide, further exacerbating the problem of climate change.

4.Soil erosion and water destruction: Forests are essential for soil conservation and water regulation. The destruction of forests leads to soil erosion, water pollution and the reduction of water resources, posing threats to biodiversity, agriculture and human life.

5.Socio-economic impacts: Forests provide many ecosystem services, such as water, food, timber, medicines, and tourism. The destruction of forests leads to socio-economic losses, affecting the livelihoods of local residents and the sustainable development of communities.

These hazards suggest that we need to pay more attention to the conservation and sustainable management of the earth's forest resources, take action to reduce destructive behavior, and promote ecological restoration and protection.

1.Soil erosion is severe.

2.There is a lack of oxygen**, and there is also a lack of natural filters.

3.The ecological environment has been forcibly occupied, and the laws of the ecological cycle have been destroyed.

4.The temperature can change, causing an unstable change in the climate.

5.The waste from the trees is burned after they are cut down, causing environmental pollution6Sandstorms are severe, and there is no natural protective wall.

Forests play an irreplaceable role in the history of human existence and development, and are known as the lungs of the earth, absorbing carbon dioxide in large quantities to continuously produce oxygen for humans and other living things. Forests are "oxygen manufacturing plants", "dust filters", "exalted natural reservoirs", and "natural air conditioners" ......The benefits of the forest are endless! The forest is also the foundation for the sustainable, rapid and healthy development of the entire national economy, and it has an irreplaceable position and role in the country's economic construction.

With the indiscriminate felling of trees, forests have been set up as protected areas in our country. But forests are constantly under the threat of fire, which can wipe out precious natural resources! Fire can cause people to lose their precious lives!

How much human civilization has disappeared in the fire? How many precious treasures were lost in the fire? China's forest resources are unevenly distributed, mainly in the northeast and southwest.

The forest quality is not high, and the forest age structure is dominated by young forests, middle-aged forests and plantations. As of 1993, China had 3,943 billion mu of forestry land, 2,006 billion mu of forest, and a forest coverage rate of 13,92. The volume of live standing timber and livestock is 11,785 billion cubic meters, and the forest volume is 10,137 billion cubic meters, ranking fifth in the world. By June 1995, the total forest area of the country had reached 13.4 billion hectares, of which more than 33 million hectares were preserved by artificial afforestation, ranking first in the world.

In March 1998, according to the latest World Forest Resources Assessment report released by the Food and Agriculture Organization of the United Nations, China's forest area was 13.4 billion hectares, accounting for 3.9 percent of the world's total forest area, ranking fifth in the world, and Chinese's per capita forest area ranked only 119th. China's total forest stock is 9.78 billion cubic meters, accounting for 2.5 percent of the world's total forest stock, ranking eighth in the world. The per capita forest stock in the world is 71.8 cubic meters, while the per capita forest stock in Chinese is only 8.6 cubic meters.

The most important impacts are ecological and climate change. The main concentration of the world's forests is the subarctic zone and the tropics, among which, the forests in the tropics occupy most of the earth, and they also contain the most species on the earth. And, because it is easier to cut down trees in the tropics than in the cold zone, tropical forests are more damaged.

The obvious, of course, short-term and local harm of deforestation is the destruction of the local ecological environment, causing soil erosion, environmental degradation, etc., desert invasion may be more serious, droughts and floods are increasing, and local species are extinct.

On a larger scale, because forests are natural oxygen bars and carbon storage carriers, carbon dioxide absorption is reduced, further accelerating global warming. Moreover, due to the loss of forests and changes in the global climate, many species may become extinct because they are unable to adapt to the new changes. Eventually, the global ecosystem will be destroyed, and the Earth will become another Venus.

It is important to note that planting trees is not necessarily intentional for the local environment. For example, Yunnan is not as rich in rainfall as it is in the tropics, but eucalyptus trees can survive. Eucalyptus trees grow quickly, but they need a lot of water, and the consequence of carrying a large number of eucalyptus trees in Yunnan is that due to insufficient precipitation, the groundwater is sucked up in large quantities, resulting in more drought in Yunnan.

Therefore, the planting of leaves should also be based on the characteristics of the original species, and try to plant the existing ones in the local area.

1 Conserve water.

In order to cherish water resources, do not let the faucet run empty, and shorten the shower time; installation of water-saving faucets; Use a water-saving flush toilet.

2 Save electricity, use as little electrical appliances as possible, and turn off the lights at will. Close the refrigerator door at all times; use of energy-efficient lamps; Purchase.

Buy high-efficiency and low-energy appliances.

3 The surge in demand for paper pulp is one of the reasons for the increase in wood consumption. The annual consumption of paper in the country is 1000

10,000 cubic meters, 1.3 million tons of imported wood pulp, the large consumption of imported paper not only caused the destruction of forests, but also caused serious pollution by the production of pulp and sewage discharge rivers and lakes (the pollution caused by the paper industry accounts for more than 30% of the entire waters). The used paper can be turned over to make scratch paper, note paper, or made into a notebook; Expired wall calendars can be wrapped in book covers.

4. Waste utilization, such as: candy paper can be folded into lighting or door curtains, old clothes can be made into mops, etc. Support and participate in waste paper

Utilization of waste glass, waste plastics and scrap metal.

5. Reduce household waste.

Consciously classify garbage.

6. Use less chemicals and buy and use phosphorus-free and biodegradable detergents;

7 Try not to use personal cars. To reduce air pollution, use public transport as much as possible to conserve energy.

Bicycle or walking; Use unleaded petrol and buy a car with a small displacement.

8 Bring your own shopping bag when shopping.

9.If you feel that the flush toilet is consuming too much water, you can put a bottle of water in the tank to reduce the amount of water used.
