If all the trees were gone, would humans still be alive?

Without trees, all hope seems to be dashed. Forests are the lifeblood of our world, and without them, life on Earth would lose its extraordinary essential functions. The loss of trees will throw the world's climate out of balance, and the services that trees provide to the planet include carbon storage, soil protection, and water cycle regulation, supporting the food systems of nature and humans, and providing the materials for countless species, including us, to build their homes.

However, we often treat trees as disposable, seemingly disposed of at will for financial gain. A 2015 study published in the journal Nature showed that we have cut down nearly half of the world's trees (about a trillion) since humans began farming about 10,000 years ago.

The vast majority of deforestation has occurred in recent times. The world's forests have declined by 32 per cent since the beginning of the industrial era, particularly in the tropics, where many of the world's 3 trillion remaining trees are rapidly falling, with about 15 billion being cut down each year.

In many places, the disappearance of trees is accelerating. In August 2019, data from Brazil's National Institute for Space Research showed that fires in Brazil's Amazon rainforest increased by 84% compared to the same period in 2018. Slash-and-burn farming is also particularly high in Indonesia and Madagascar.

Of course, unless there is an unimaginable catastrophe, we will not cut down every tree on the planet. But we can imagine a "Mad Max"-style dystopian world, where all the trees on Earth suddenly disappear and we may realize how lost we would be without them.

Trees are irreplaceable, and if all the trees were cut down, we would be living on a planet that may no longer be able to feed us.

If all the trees are gone, it will be very difficult for humans to survive because there will be less oxygen.

No, because then human beings will not be able to live without oxygen.

If there are no trees, there will be no air, and the air quality will suffer, and it is estimated that it will be difficult to survive in the long run.

This one must not survive, because trees have a very large role for human beings.

It can exist, but the climate or the degree of wind and sand cannot be guaranteed.

The trees are gone, and humans will certainly not survive because oxygen is scarce.

This should not be possible, after all, trees are still very useful for people to survive and produce oxygen

If the trees are gone, it seems that people will not be able to survive because there is no oxygen.

If all the trees were gone, there would be no way to get the oxygen that people needed to survive.

Without trees, it will lead to soil erosion, flooding, strong winds, a significant drop in air quality, greater damage from typhoons, a warmer climate, melting snow and ice, and homelessness for animals.

1.Lack of plant absorption of solar heat has led to a sharp rise in the earth's temperature, leading to the melting of glaciers and the North and South Poles, and the rise of sea levels.

2.The lack of vegetation protection in the surface soil increases the probability of mudslides occurring in the event of heavy rains.

3.Rainwater cannot penetrate the ground sufficiently, resulting in a shortage of fresh water on the surface.

4.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.

5.The lack of CO2 absorption exacerbates the greenhouse effect, and the depletion of oxygen in the atmosphere directly leads to the extinction of human beings.

In the boundless universe, the Earth and the Moon are the two closest planets to each other. The earth has water, vegetation, and life; The moon has a sea (moon sea) without water, and there are mountains (craters) without trees and no life. The presence of people and animals such as Chang'e, Wu Gang, White Rabbit and Osmanthus Tree on the moon is just a beautiful imagination of people, but in fact it does not exist.

The presence or absence of vegetation is the most fundamental difference between the earth and the moon, and "vegetation" is a general term for the plants that cover the earth's surface. In different seasons, people will use different quilts, such as towel quilts, silk quilts, eiderdown quilts, etc., to protect and warm their bodies. Vegetation is like a quilt covering the earth, and it also protects the earth.

However, the role of vegetation goes far beyond conservation, it also directly or indirectly feeds all living beings on the planet, including people. The necessary conditions for the survival of organisms are the ** of oxygen, water and food, and plants are precisely the providers and regulators of these three necessary conditions, without which there would be no other organisms on the earth.

The Earth's surface atmosphere contains about 25% oxygen, and if this oxygen content is taken as 100%, the oxygen content in the air decreases by 10% for every 1,000 meters of altitude gain. Everyone knows that without oxygen a person dies of ventricular death. Even at an altitude of 3,000 meters above sea level, due to the obvious drop in the oxygen content in the air, some people will begin to suffer from altitude sickness and feel difficult to breathe.

At altitudes above 7,000 meters above sea level, it is already unbearable for ordinary people and will produce altitude sickness. Where does oxygen come from on Earth? In the process of biological evolution, green plants have acquired the ability to use the energy of sunlight to synthesize water and carbon dioxide into sugars, and at the same time release oxygen.

In the process of the evolution of the earth, with the production and development of green plants, the oxygen in the earth's air has become more and more abundant, reaching the current relatively stable equilibrium state. When plants synthesize sugars, the carbon dioxide absorbed by them is the most important for the respiration of living organisms or various combustion processes on the earth. On Earth, plants are the key to the mutual conversion and balance of oxygen and carbon dioxide, and their role is irreplaceable.

It can be said that without plants, there would be no oxygen necessary for human respiration, and the necessary conditions for human survival would be lost.

Plants directly provide an extremely rich food for humans. For example, rice, flour and other grains that human beings need every day, edible oils such as soybean oil, sunflower seed oil, olive oil, and various vegetables and fruits. All of these are taken from the roots, stems, leaves, flowers, fruits, and seeds of plants.

They are rich in starch, protein, fat, and various vitamins that human health needs. In addition to food that can be directly eaten by humans, raw materials such as cotton textiles, sugar industry, wood processing industry, paper industry, and food processing industry also come from plants. Although the meat and dairy products consumed by humans come from animals, many animals, including domestic animals, such as cattle, sheep, pigs, chickens, ducks, geese, etc., are mainly based on plants.

It can be seen that plants are at the base or bottom of the earth's food chain, and without plants, there would be no food source for humans and other organisms.

If the trees are not dug up, the earth will lose important oxygen**, and everyone knows that the photosynthesis of green leaves will produce oxygen rations.

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 selling, and the long trees are not afraid, but the leaves are greener!

If there were no trees, the storm would have washed away the house.

If there were no trees, the birds would have no home and the beasts would have no habitat. The bird will be on the verge of death.

If there is no tree anymore:

1. The rapid rise in the earth's temperature has led to the melting of glaciers and Antarctic ice, the rise of sea levels, and the significant reduction of land mass. Including several famous international cities: New York, Shanghai, Tokyo and Sydney will disappear.

2. Lack of vegetation protection in the surface soil, soil erosion, flash floods, mud bluffing, scorpion and scorpion flows, and arid and desertified land. Arable land will be drastically reduced, some animals will become extinct, and food will be scarce for humans.

3. The earth's oxygen is gradually decreasing and carbon dioxide is increasing, which may endanger the survival of animals and humans. At least the earth can't accommodate so many humans now.

4. If human beings can survive, many industries and transportation industries will disappear, and there may be no electricity, coal, etc., and human beings may enter the primitive era again. It is also possible to break out into a major war, self-destructive.

The environment deteriorates, the air quality deteriorates, and eventually the earth is no longer habitable for humans. Plants are food, materials, oxygen generators. Rainforests are known as the lungs of the earth, and wetlands are known as the kidneys of the earth.

Without plants, herbivores are extinct, and without herbivores, carnivores are extinct.

In short, take care of the environment!

Temperatures have risen sharply, soil erosion has made oxygen thin or non-existent.

Nature is all complementary to each other, everything has its own purpose, if there are no trees, there is no source of oxygen, maybe there is no life, or maybe life will find its own way.

My people have a person at the time of my people.

If there are no trees, there will be: mudslides, sandstorms, floods, **......
