Within 20 years!If 8 billion trees are planted each year, what will affect the earth's climate?

The relationship between tree planting and global climate

If we planted 8 billion lessons on the earth each year, what will happen for 20 years, what will happen to the earth?

Politicians, business leaders, young people, and celebrities on the earth are calling on everyone to plant millions, billions, or even trillions of trees to improve the climate.

There are currently nearly 8 billion people on the earth. If everyone grows a tree every year in the next 20 years, this will produce 160 billion new trees.

Can a large number of trees really slow down the deterioration of the climate?

Trees and carbon

Carbon dioxide is the main gas that causes global warming. Trees and other plants will turn carbon dioxide into carbohydrates through photosynthesis. They use these carbohydrates to generate stems, leaves, and roots.

The amount of carbon that can be stored in each tree is very different. This depends on the type of tree, the area of ​​growth, and the age of the tree.

Let us assume that a tree can absorb 50 pounds of carbon dioxide each year, and each person is planted in one year in 20 years, and each tree is survived, which is unlikely to happen-these 20 trees will be every year. Absorb carbon dioxide with about 1,000 pounds (that is, half tons).

In the United States, the per capita carbon dioxide per capita reaches an amazing 15.5 tons, while India per capita generates 1.9 tons per year. This means that if everyone grows an average of a tree every year in the United States, when these 20 trees grow, they can only offset 3%of their annual carbon dioxide. But if in India, 26%of carbon dioxide will be offset each year.

Planting trees is naturally an important way to solve climate problems, but there are more important ways to really solve it.

Protect the existing trees

There are about 3 trillion trees on the planet, and this number is only half of the time when human civilization just started to develop 12000 years ago.

Human beings are about 15 billion trees every year. Many of these trees grow in tropical forests, but now almost the world is cutting from forests.

Protecting the existing forest is very meaningful. The forest can not only absorb carbon dioxide, but also the place where many animals habitat, we should protect it. Trees can provide humans with fruit and burning firewood. In the city, they can provide trees and leisure places.

But trees should not be planted in places where there have been no trees, just like native grasslands, tropical rare tree grasslands. These ecosystems provide an important living environment for the native animals and plants there. If the environment there has never been changed, a large amount of carbon has been stored.

Make more effort

To slow down the deterioration of the climate, people need to do more in addition to planting trees. We need to quickly develop new renewable energy sources, just energy such as solar energy and wind energy to reduce the discharge of carbon dioxide and other greenhouse gases. Similarly, you need to reduce the number of driving and flight and eat less meat, because when the meat is transformed, there are more carbon released in each calories than vegetables and grains.

Everyone in the society, including businessmen, politicians, governments, adults, and children, they need to do their best to do something to reduce fossil fuel emissions. Think about what a person should do to help a planet improve the environment. This is a very stressful thing. Fortunately, there are many ways to do it.

Volunteers of local environmental protection organizations are a way to protect and restore local habitats. In addition, you can discuss new travel methods with your family, such as riding a bicycle, walking or taking public transport, and using these green travel methods to instead of driving private cars.

In addition, don't be afraid of the protection of trees in the local or global leadership. Two 11 -year -old girls have led a action to eliminate palm oil because they are worried that tropical rain forests will be destroyed by palm oil.

Sometimes the climate change is slow, but after people work together, this will eventually happen.

related information

Climate, including temperature, humidity, air pressure, wind (including wind direction and wind speed), precipitation, atmospheric components, and many other meteorological elements for a long time (generally decades or more) and a comprehensive summary description based on statistical data in specific areas In addition to the "average" of the weather, it also includes the changes in weather and extreme conditions, and the occurrence of abnormal conditions [1]. Compared with the climate, the weather refers to the real -time state of these weather elements in the past two weeks.

The climate of one place is affected by the latitude, terrain, altitude, ice and snow coverage of the place, and the water flow status nearby and its water flow. The climate can be classified according to the average and special range of different meteorological elements. The most commonly used category system is the most commonly used category system. The Sanvitt climate classification system, which was used in 1948 [2], increased the amount of soil moisture steaming on the basis of two variables of temperature and precipitation. The system was used to study the potential effects of animal species diversity and climate change. Berjeon and the space weather classification system focuses on determining climate conditions in certain areas through the formation of gas groups.
