Can tree planting really control environmental degradation?

At least for the air, I think trees are of great help. Photosynthesis plays an irreplaceable role in the cycle of carbon dioxide and oxygen. It plays a great role in purifying the air and preventing the increase in carbon dioxide concentration. It is also a good adjustment for human vision. People nowadays are always happy to see the green color of trees.

Thank you for your participation precisely because many people only see short-term effects, but the longer the experience period, you will find from a balanced perspective that these are not true, but just an illusion.

Trees are indeed effective in purifying the air, retaining water and soil, and preventing wind, but I personally think they are not the key to solving the problem. Water pollution and other issues cannot be solved by trees.

Trees can purify the air and produce oxygen； Prevent soil erosion ； Windproof and sand-fixing ； Providing a good living space for humans and other animals and plants is a very important part of the earth's ecological balance ； People feel happy when they see green. Human beings cannot live without trees. Only with trees can nature be alive and the human environment be beautified and improved.

Planting trees is a good way to reduce CO2 emissions and is now needed for biomass utilization. It is reported that some companies are already studying the role of tree planting in these two aspects and have entered the implementation stage.

Afforestation, returning farmland to forest and ecological reconstruction are extremely important. Treat desertified farmland, control soil erosion, prevent wind and sand fixation, and increase soil water storage capacity. * * Improve the ecological environment and reduce losses from flood disasters. As the economic forest gradually enters the mature stage, it will generate huge direct and indirect economic benefits. It can also provide a large number of labor and employment opportunities and promote the sustainable development of the local economy. The huge forest carbon sink will play a positive role in protecting the global climate system and ecological environment.

Afforestation can conserve soil and water and effectively control soil erosion and land desertification. In many places in our country, vegetation coverage is low and soil erosion is serious. Especially in the Yellow River Basin, due to the loose soil, during the rainy season, rainwater washes away and a large amount of sediment flows into the Yellow River, causing the river water to become muddy and the river bed to rise, which brings huge difficulties to flood control work. Planting more trees can control soil and water loss. Because trees have huge root systems, these roots hold the soil tightly like giant hands. The water in the soil is absorbed and stored by the tree roots. According to statistics, one acre of forest can store 20 tons more water than an area without forests. To control deserts, the most effective and important method is to plant trees. Because "the main weapons of the desert to attack humans are wind and sand" (Zhu Kezhen said), large-scale afforestation can form protective forests, reduce the speed and force of wind, stabilize sand dunes, and control wind and sand.

Moderator, the answer should be yes. The benefits of planting trees are almost summarized by the people above, but planting trees can only help solve environmental problems in some aspects. By itself it does not really “solve” environmental problems. Then, you might as well post the basis for your reply to the second floor so that everyone can further discuss it.

There's no need to boast, you think?: Plant trees, and the plants will either burn or be decomposed by microorganisms. As a result, carbon dioxide will be produced, so the conclusion is: Planting trees will only be a short-term action, not a long-term idea.

hehe. Did the host think about it himself? It's a great idea. However, just because too much carbon dioxide is causing the greenhouse effect cannot be solved by planting fewer trees. More important are other sources of carbon dioxide.

My point of view is that planting trees alone cannot control the environment, but it should help solve environmental problems. For example, planting trees may bring disadvantages as well as benefits. The advantage is 2 and the disadvantage is -1, so it should still be beneficial.

Maintaining appropriate forest coverage is one of the best ways to maintain a beautiful homeland. It has many benefits. Today's situation on the loess high slopes is the result of yesterday's destruction of forests. Afforestation cannot control pollution (some trees have this ability), but it is one of the positive steps we must take now. Pollution control is not a matter of years or decades, but a long-term task of mankind. Trees have their own cycle, and old age outweighs merit, but you cannot deny the contribution of young adults! Don’t stop eating because of choking. If we follow this logic, will the Amazon forest be cut down and burned to death? Hey, the poster should not be extreme:'(

Plants will produce CO2 when burned or decomposed, but compared with the amount of CO2 produced by our industry, which factor is greater? I don’t know if the poster has thought about it. I personally think that industry produces the majority of CO2. After all, microbial decomposition is a long-term process, and combustion does not happen all the time.

Planting trees can purify the air and absorb carbon dioxide in the air, so it is very helpful for environmental improvement, especially in the long run.

The carbon dioxide produced by the decomposition of trees is the same as the carbon dioxide produced by the decomposition of the tree's body after death. The matter in this world is balanced.

Most of the places with good greening are places with good environment. How many places have good greening but poor environment? I wonder if a tree can survive in a severely polluted place?

It can still improve the microenvironment. But what really has the greatest impact on the environment is the ocean.

It is good for the environment in the short term, but artificial forests are far inferior to natural forests. They require continuous artificial watering and fertilization to eliminate pests and diseases. They do not have the immunity of natural forests and will be destroyed at any time!

I think it is useful, at least it seems to make me feel comfortable. The bare land is so chilling

Most people believe that tree planting is always beneficial to the environment. However, if the specific conditions of a certain area are not considered and the selected tree species are inappropriate, tree planting may have an adverse impact on the environment and even damage the local ecology. A global study by a team at Duke University in North Carolina, USA, weighed multiple aspects involving plants and concluded that planting trees does not necessarily equal environmental protection. 　　Plants use carbon dioxide in the air to grow, and planting large forests displaces the gas in the atmosphere, thus preventing global warming. However, large amounts of forest require large amounts of water. The team studied more than 500 newly planted forests around the world in the past half century. Among these forest areas, 13% of the surrounding streams were completely drained within a year. On average. Tree planting has cut off more than 50% of local streams. When they visited South Africa, they discovered that in some places pine trees were draining local streams. 　　Planting trees in different areas will have different impacts on the environment. For example, the environmental protection effects of planting trees on barren hills and crop fields are different. The team found that people planting trees in crop fields may have adverse environmental impacts because growing trees in crop fields uses more water. This situation will reduce people's use of water for drinking and irrigation, and damage the local water ecosystem. The study also found that forest soils are more likely to become saline and acidic than other types of plants, such as crops or green spaces. 　　Why does this happen? This is partly because plant plans in some places select species that grow quickly and absorb more carbon dioxide, and these trees grow year-round and remain green year-round. This means the trees absorb large amounts of carbon dioxide and water, thus draining streams of water. 　　However, planting trees in crop fields to change water flow is not necessarily a bad thing for the environment. For example, planting trees in some agricultural areas in the United States can reduce the loss of land fertility into the sea, preventing algae from growing wildly in the sea and killing other aquatic plants.
