Are trees good or bad for the environment, and how important are trees to the environment?

It's harmful to the environment.

For example, fire hazards, Yunnan fires, and people suffered.

There are two sides to everything. It's also beneficial.

Trees can purify the air for human beings, beautify the environment, wood can be used to make paper, construction and many other purposes, we must plant trees, care for trees, pay attention to fire protection forests. Create a better living environment and make greater contributions to mankind. Trees can beautify the environment, release green energy, and are indispensable in natural resources, and human beings should take care of them.

In addition, there is an inhibitory effect on trees!

It can stabilize the soil and prevent wind and sand! Purify the air, beautify the environment,! Absorb carbon dioxide in the air, a small amount of sulfur monoxide and other gases, and release oxygen!

Reduce the thermal effect of the city! Wood can be used for fuel, tools, furniture, decorations, etc., and can also be used to make paper, etc.! It can purify carbon dioxide and improve air quality, and flowers and trees should be cared for.

There are too many benefits of being able to do oxygen and keep the soil from being lost, first of all, it is to purify the air we need, purify the water source, and then regulate the temperature, prevent wind and sand fixation, and so on. Fewer trees should be cut down and more trees should be planted.

Trees can absorb carbon dioxide and release oxygen, purify the air, prevent wind and fix sand, and can also block sunlight, which is convenient for cooling, and some tree fruits can also be eaten. We can plant trees and use less paper towels and disposable utensils. Produces oxygen, prevents soil erosion, and participates in the water cycle.

We should not litter waste batteries, do not litter plastic bags, and do our part to protect the trees and purify the air.

Beautify the environment, regulate temperature, produce oxygen, absorb carbon dioxide,. When the tree grows, you can enjoy the shade of it, and when you are old, you can use it to make wood products and use it as firewood. Protecting trees is everyone's responsibility.

Trees regulate the climate and maintain ecological balance. Through photosynthesis, trees inhale carbon dioxide and exhale oxygen, making the air clean and fresh. One acre of forest releases enough oxygen for 65 people to breathe.

Produces oxygen, prevents soil erosion, and participates in the water cycle. We should not litter waste batteries, do not litter plastic bags, and do our part to protect the trees.

It is particularly important that with these trees, the environment can be made better, and trees can also play a role in purifying the air, preventing sand, and can have a greener environment.

It is very important that many animals depend on forests for their lives, and trees can produce a lot of oxygen, which also has many benefits for humans.

It is very important to protect it, but it also maintains the ecological balance, and it also serves to purify the air.

Trees have the effect of purifying the air, they absorb carbon dioxide, sulphur dioxide and absorb dust, so we feel that the air in the forest is cleaner. In addition to this, the roots of the trees grow inside the land, and their presence is like a large net that prevents soil erosion and fixes the soil.

What are the benefits of trees for the environment

In our living environment, trees are very common plants, such as street trees on both sides of the road, greenery in communities and schools, these trees are closely related to our lives, and they also have a good protective effect on the environment.

First of all, trees have a certain effect of purifying the air, they can absorb carbon dioxide, sulfur dioxide and many other gases, and it also has the effect of absorbing dust in the air, so we usually feel that the air is very fresh in the mountains and forests.

Secondly, trees also have a certain role in preventing soil erosion and fixing the soil, because the roots of trees will grow in the soil, and their presence is like a big net that can prevent the wind from blowing away the soil.

1. First of all, trees or reeds have a certain effect of purifying the air, they can absorb carbon dioxide, sulfur dioxide and many other gases, and it also has the effect of adsorbing dust in the air, so we usually feel that the air is very fresh in the mountains and forests.

2. Secondly, trees also have a certain effect of preventing soil erosion and fixing the soil type, because the roots of trees will grow in the land, and their existence is like a shirt with a large net, which can prevent the wind from blowing away the soil.

1.Contains nutrient water sources.

2.Purify the air.

3.Fix the soil.

4.Reduce noise.

5.Landscaping.

6.Shade and radiation protection.

The dense canopy of trees and the green foliage block sunlight and absorb the sun's radiating heat, thus reducing the temperature in the small environment. Trees are like huge pumping machines, which continuously absorb the water in the soil into the tree, and then diffuse most of the water absorbed by the roots into the atmosphere in the form of water vapor through the transpiration of the leaves, thus improving and regulating the relative humidity in the air. Trees also play an important role in protecting the environment on which humans depend.

We know that high winds can increase soil evaporation, reduce soil moisture, and cause soil erosion. In severe cases, sand storms can bury towns and farmland. According to the statistics of the United Nations in 1984, 6 million hectares of land are buried by sand every year, 21 million hectares of land are lost due to desertification, and 1 3 of the world's land is currently in danger of desertification, and the international community is called on to fight to stop desertification in some parts of the world.

If you want to live in the sand, you need to plant more trees. "The effective way to prevent wind and sand fixation is to plant trees and set up shelterbelts to reduce wind speed and block the erosion and migration of wind and sand. Trees can secrete fungicides to kill various germs in the air; In addition, it can also absorb toxic gases emitted by industrial production, retained smoke and dust that pollute the atmosphere, and eliminate noise pollution harmful to humans.

The benefits of afforestation to the environment: afforestation can conserve water and soil, afforestation can prevent wind and sand fixation, afforestation can purify the air for human beings, afforestation can remove pollution, and afforestation can reduce noise pollution.

1. Afforestation can conserve water and soil

Afforestation can conserve water and soil, **vegetation coverage is low, **every rainy season, there will be a large amount of sediment into the river, destroying the fields, filling up the riverbed, silting up the estuary, and causing great harm.

To curb soil erosion, it is necessary to plant trees, because trees have a root system as large as a canopy and can hold on to the soil like giant hands. The water of the soil that is caught and deprived of the first place is constantly absorbed and stored by the roots of the tree. According to statistics, green forest forest 7 stores 20 tons more water than non-forest area.

2. Afforestation can prevent wind and fix sand

Wherever the wind and sand go, the countryside will be buried, and the city will be reduced to ruins. To resist the attack of wind and sand, it is necessary to create shelterbelts to weaken the force of the wind. Once the wind meets the shelterbelt, the speed is reduced by 70 80.

If you arrange many forest belts in parallel at a certain distance and plant grass, then the amount of sand and gravel that can be blown by the wind will be reduced.

3. Afforestation can purify the air for human beings

We know that humans inhale oxygen every day and inhale carbon dioxide, and the tree is the opposite, its leaves are constantly photosynthesizing under the sun, inhaling carbon dioxide, releasing oxygen. According to statistics, one acre of forest can absorb 67 kilograms of carbon dioxide and release 49 kilograms of oxygen every day, which is enough for 65 adults to breathe.

4. Afforestation can remove pollution

Trees can stick to the dust in the air, making the air clean and fresh. Scientific tests have shown that one acre of forest can absorb 4 kg of toxic gas sulfur dioxide in a month, and 20 tons and 60 tons of dust in a year.

One acre of pine and cypress can secrete 2 kilograms of fungicide for two days and nights, which can kill tuberculosis, typhoid, diphtheria, dysentery and other bacteria.

5. Afforestation can reduce noise pollution

Trees planted on both sides of the road can reduce noise, and a variety of tree types, flowers and fruits, and verdant branches and leaves can beautify the environment, providing an ideal environment for people to study, work and live.

The benefits of afforestation to the environment: it can reduce air pollution, maintain water and soil, prevent wind and fix sand, reduce noise, beautify the environment, etc., and play a very important role in improving the ecological environment.
