Without trees, oxygen will be reduced. Due to photosynthesis.
It is produced by plants, so if there are no trees, there will be a lack of oxygen, there will be no paper to use, and desertification will be serious. There are also many trees that 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.
Extended Information: The trunk is divided into five layers.
The first layer is the bark, which is the top layer of the trunk that protects the body of the tree and prevents the invasion of diseases, and the phloem is underneath the bark.
This fibrous tissue transports sugars from the leaves.
The third layer is the cambium layer, which is very thin and is the growing part of the trunk from which all other cells come from.
The fourth layer is the sapwood, which transports water from the roots to the rest of the tree, and is usually lighter than the heartwood.
The fifth layer is the heartwood, which is the old sapwood, and the two are collectively called xylem.
The trunk is mostly heartwood. When the tree grows, its roots will entangle the soil beneath its body, preventing water and soil flow.

Without trees, the earth would lose vital oxygen**, and everyone knows that the photosynthesis of green leaves produces oxygen.
If there are no trees, the soil will be lost, the soil will be desertified, the land will become a desert, there will be no plant, and there will be no food for humans. Without trees, a large amount of land would become a desert, and people would be uninhabitable, and humanity would face the danger of losing its homeland.
Without trees, sandstorms and storms would be devastating to humanity. The trees are so deeply rooted in the soil that even a tornado can hardly uproot a tree in a large woods. The time under the storm is very long, and the trees are not afraid, but the leaves are greener!
If there were no trees, the storm would have washed away the house.
Without trees, birds would have no home, and wild animals would have no habitat. The bird will be on the verge of death.

Consequences of not having a tree:
1. High winds, dust, soil desertification, drought, floods, soil erosion, rising temperatures, and destruction of biodiversity.
2. Lack of plant absorption of solar heat, the earth's temperature has risen dramatically, resulting in the melting of glaciers, the north and south poles, and the rise of sea level.
3. The lack of vegetation protection in the surface soil will cause mudslides in the event of heavy rain, and the probability of major floods will increase.
4. Rainwater cannot fully penetrate into the ground, resulting in a lack of fresh water on the surface.
5. The above reasons lead to difficulties in the survival of all animals, difficulties in the growth of other plants, and failure of crops. Food is scarce. To be precise, solar energy cannot be converted into chemical energy that can be absorbed, decomposed, and used by living organisms.
6. Lack of CO2 absorption, the greenhouse effect is more serious, and the oxygen in the atmosphere is depleted, which directly leads to the extinction of human beings.
The role of trees: 1. Trees are dust filters. When a dusty air stream passes through a woods, the dust with larger particles in the air drops rapidly as the wind speed decreases.
In addition, some trees have fluffy or oily skins that can stick dust to their bodies, resulting in a much lower dust content in the air flow passing through the trees.
2. The forest has the effect of dust removal and filtration of sewage. Industrial development, soot, dust, and exhaust gases emitted seriously pollute the air and threaten human health. The folds, hairs on the leaves of tall trees, and the viscous oil and sap secreted from the stomata can be intercepted to a large amount of fine dust, which has obvious blocking, filtering and adsorption effects.
3. Trees are experts in sterilization. Many trees secrete cidin during their growth to kill various pathogens brought by dust. According to the survey, the amount of bacteria per cubic meter of air is 4 million in department stores, 580,000 on boulevards, 100 in parks, and only 55 in forest areas.
4. Trees are also natural reservoirs. The decay layer of litter and leaves on the surface of the forest continues to increase, forming a thick humus layer, like a huge sea that absorbs rainwater, which has the functions of strong water absorption, delaying runoff and weakening flood peaks.

The absence of trees poses a variety of hazards, and here are some of the possible effects:1Climate deterioration:
Trees absorb carbon dioxide from the atmosphere and produce oxygen, helping to adjust the climate and reduce the effects of global climate change. The lack of trees leads to an increase in carbon dioxide concentrations, which can lead to increased climate change. 2.
Soil erosion: The root system of trees anchors the soil and absorbs rainwater, preventing soil erosion. The absence of trees makes the soil poor and susceptible to soaking, which can lead to things like flooding, landslides and soil erosion.
3.Water insufficiency: Trees are able to store water during rainfall and release it into the atmosphere through evapotranspiration.
A lack of trees can lead to a lack of water**. 4.The ecological balance is disrupted:
Trees are an ecological system that is pure and is the habitat and food of many species in the town. The lack of trees can lead to the destruction of the ecological balance, which not only affects plants and animals, but also has a great challenge to the protection of the earth's biodiversity. 5.
Air pollution: Trees can absorb pollutants from the air, but the absence of trees can lead to increased air pollution, causing harm to human health and the environment.

Trees play an important role in our ecosystem, and their lack of them will have a negative impact on our lives. Without trees, we would have lost a lot.
First, without trees, we would lose a lot of ecosystem services. Trees absorb carbon dioxide and release oxygen, maintaining the balance of oxygen levels and greenhouse gases in the atmosphere, and they also provide habitat for other organisms. Without trees, we would lose important hydrological services.
Trees are able to intercept rainwater and absorb it into the groundwater system, and the lack of trees can lead to damage to the natural water cycle, which will have a significant impact on life on land.
Second, without trees, we will face a serious food security crisis. The economy and cultural practices of many countries depend on the production of plants, many of which depend on the fruits or nuts of trees, such as apples, oranges, grapes and nuts. In addition, Shushen Chun provides many medicinal raw materials and wood, such as rubber trees, eucalyptus trees, and pine trees, the lack of which threatens the medical and construction industries.
Finally, without trees, we would lose much of our culture and identity. Many cultures and fields of tradition, religion and art are closely associated with trees. In some cultures, trees are seen as a link between man and nature, which has a symbolic meaning.
Trees are also used as landmarks and coats of arms in many places and fields, symbolizing certain values.
Destroying trees will cause great harm to our ecosystems and our lives. Protecting trees and forests is our shared responsibility. We can plant trees, build sustainable economic systems to protect and maintain our forests, and ensure that we continue to benefit from these services and benefits that trees provide.

Without trees, there is no oxygen and no life. Trees use carbon dioxide and water as raw materials for photosynthesis to produce oxygen and sugar, which is one of the necessary gases for our breathing and is the basis of life activities. Sugar, on the other hand, provides food and energy to sustain life activities.
In addition, trees also play a very important role in the environment, maintaining ecological balance and environmental stability.
Further expanding and extending the view, trees also have an important place in human civilization. The wood from trees is used to build houses and make furniture, leaves and bark are used to make herbs and chemicals, and fruits and nuts are delicacies on our tables. In addition, trees can also be used for windproofing, water retention and landscaping functions, and also play an important role in the process of urbanization.
However, with the continuous expansion of human activities, the forest area is decreasing, and the forest ecosystem is being destroyed, which has led to problems such as climate change and environmental pollution. This forces us to reflect on the use and protection of tree resources, develop sustainable forest management practices and eco-tourism, increase the coverage of green spaces and gardens, and strengthen the protection and restoration of forests to protect the ecological environment, maintain climate balance, and contribute to human health and life.
To sum up, there is no oxygen and no life without trees, and trees also play an important role in human civilization and environment. We should recognize the importance of trees and actively protect and develop forest resources to maintain ecological balance and promote sustainable development. <>

Sandstorms, floods... The land will be desertified, and many animals will have no habitat. Humans can't make paper anymore, what does it mean to live without paper?
What should I do after going to the toilet?。。 There are many disasters without trees, so think for yourself!!
What is that Happy Home 538 I remind you, can having a tree prevent a house from collapsing? You say that you can't grow plants in the desert, isn't the cactus a plant? What can't you live in the desert?

Without trees, oxygen will be reduced. Since photosynthesis is produced by plants, there will be no oxygen without trees, there will be no paper to use, and desertification will be serious. Without trees, it can lead to soil erosion, flooding, strong winds, a significant drop in air quality, even more damage from typhoons, a warmer climate, melting snow and ice, and homeless animals.
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.
Extended information: Natural variation on Earth, including natural variation induced by human activities, natural disasters are born in the Earth's surface environment composed of the atmosphere, lithosphere, hydrosphere, and biosphere. It does not happen again all the time, and when this kind of mutation brings harm to human society, it constitutes a natural disaster.
Because it has brought varying degrees of damage to human production and life, including the relationship between man and nature with labor as the medium, as well as the relationship between people related to it.
Disasters are all negative or destructive effects.
Therefore, natural disasters are a manifestation of the contradiction between man and nature, which has the dual attributes of nature and society, and is one of the most severe challenges faced by mankind in the past, present and future.

The earth is a place with mountains, water, and air. Among them, trees can be said to play an important role, not only to maintain water and soil, but also to provide shade and sun, regulate the air, and even sacrifice themselves. If you suddenly find that there are no trees, the birds will lose their homes, the earth will lose its life, and human beings will lose their civilization.

If there are no trees, there are several problems:
1. The air quality is reduced, because there are no trees, there will be very few plants that can photosynthesize and produce oxygen, especially in winter, after the grass wilts.
2. Wooden daily necessities such as wooden dining tables, wooden chairs, and wooden chopsticks in our lives will no longer exist, and can only be metal or stone.
3. Paper will be a luxury, because a large part of the paper we use in daily life is made from trees.
4. It will also become impossible to drill wood for fire, because without trees, there will be no drilling wood for fire.
5. Many wooden carvings have become out of reach, because without trees, there would be no wooden carvings.
6. Without trees, the desertification of China's land will be more serious, and the earth will no longer be suitable for human survival.
-
There is a massive decrease in oxygen, soil erosion, and desertification of the land.
The various substances on which human beings depend for survival will be reduced.
In summary, the role of trees can be broadly divided into the following plus points:
1. Photosynthesis, absorbing carbon dioxide and releasing oxygen.
2. Transpiration, regulating air humidity.
3. Fix the soil and prevent soil erosion.
4. Barrier function, wind and sand.
5. Increase greening and beautify the environment.
6. Appreciating the value of beauty and increasing the artistic component.
7. Industrial value, wood, wood carving and other wood products.
8. Medicinal value, made into medicinal materials.
9. Trees can reduce noise pollution. A 40-meter-wide forest strip can reduce noise by 10-15 dB10, and the secretions of trees can kill bacteria. There are thirty or forty thousand bacteria per cubic meter of air in the clearing, and only three or four hundred in the forest.
Pain perception is an effective monitoring system, but this monitoring system is too big. The principle of the formation of pain fear in evolution is similar, and both play a role in risk aversion, but the high complexity of the environment determines that this relatively primitive strategy can sometimes lead to some *** - such as a large number of fear in the face of danger. >>>More
When the speed of man is indeed the speed of light, then there is a polar world of light and darkness around him, because the speed of man and light is synchronized, so man sees everything in black and white, if the speed of man is greater than the speed of light, then you can distort time, because you can see the sun tomorrow today, then if your speed is less than absolute 0 then time will go backwards, everything will stand still and go back to the past.
Animals will be fatally injured. If the high-voltage electricity leaks into the river, then the animals in the river will be injured by the high-voltage electricity, which will lead to death.
Flowers and trees will flourish, rivers, lakes and seas will be more beautiful, the air environment will be good, animals will thrive, the biological chain will not be destroyed, and it will be completely natural. >>>More
