The Importance of Forests 10, The Importance of Forests

If there is no forest:

1 Producing climatic anomalies.

Without forests, the evaporation of water from the surface will increase significantly, causing changes in the surface heat balance and heat distribution in the troposphere, and the temperature near the ground will rise, and the temporal and spatial distribution of rainfall will change accordingly, resulting in climate anomalies and local climate deterioration, such as reduced rainfall and increased sandstorms.

2 Increase CO2 emissions.

Forests play an important role in regulating the amount of carbon dioxide in the atmosphere. Scientists believe that the world's forests collectively absorb about 1.5 billion tonnes of carbon dioxide per year, equivalent to 1.4 of the carbon dioxide released by fossil fuel combustion. Deforestation reduces the ability of forests to absorb carbon dioxide, releasing carbon that would otherwise be stored in organisms and the surrounding soil.

The Food and Agriculture Organization of the United Nations (FAO) estimates that more than 1.5 billion tonnes of carbon dioxide are released into the atmosphere each year as a result of deforestation of tropical forests.

3 Species extinction and biodiversity loss.

Forest ecosystems are one of the most species-rich areas. Thousands of plant and animal species are threatened with extinction due to worldwide deforestation. The rainforest's flora and fauna may include half of the known species, but it is disappearing at a rate of 4.6 million hectares per year.

4. Exacerbate soil and water erosion.

Large-scale deforestation often causes severe soil erosion, exacerbating natural disasters such as desertification, landslides and mudslides.

5. Reduce water conservation and exacerbate flood disasters.

Deforestation also fundamentally reduces the water-holding capacity of the soil, and the siltation of rivers and lakes caused by soil erosion leads to widespread flooding, exacerbating the impact and harm of flooding.

I support the answer above.

If there is no forest, it is like a person without lungs.

One of the most important functions of forests is to convert carbon dioxide into oxygen, which is consumed by living organisms.

In addition to the above, there is also the regulation of the mind.

Without the forest, we would not have wooden furniture.

Importance of protecting forests: Forest resources are essential for the maintenance of biodiversity.

Maintain climate stability, regulate the atmospheric environment, maintain water and soil, and fight natural disasters.

It is also the most important resource source on the earth, providing a large number of valuable resources such as wood, coal, oil and gas for human production and life, and also providing rich food for human beings, so it is of great practical significance and role to effectively protect forest resources.

The degree of protection of forest resources is closely related to people's survival and development, and the progress of human production activities and industrial level has caused great damage to forest resources, and if effective protection measures cannot be adopted in time, forest resources may be destroyed.

Although environmental protection and the protection of forest resources have become a hot issue in society, and many countries have also made outstanding achievements in the protection of forest resources, it is still necessary to bear in mind the lessons, regard the protection of forest resources as a persistent work content, and strictly prohibit any behavior that threatens and destroys forest resources, so that forest resources can continue to provide a guarantee for human progress and development.

Manner. First of all, it is necessary to prohibit indiscriminate cutting and deforestation, and change the backward thinking of "relying on the mountains to eat the mountains". China**.

has been on natural forests, primeval forests.

Logging is strictly prohibited. For some residents living in the deep mountains and old forests, they should change the concept of "relying on the mountains to eat the mountains" in the past. Excessive deforestation not only destroys vegetation, but can also trigger mudslides.

and other disasters. At the same time, China has formulated and implemented a number of forestry ecological engineering plans to vigorously plant trees and protect the ecological environment. The Three-North Shelterbelt System Project started in 1978.

From Heilongjiang to Xinjiang, a lot of desertified land has been treated for decades. In addition, there are projects such as the shelterbelt system in the middle and upper reaches of the Yangtze River and the coastal shelterbelt system.

Dust storm. It is a catastrophic weather phenomenon in which wind and sand interact, and its formation is inextricably related to factors such as forest decline, species extinction, and climate anomalies. Among them, the overexploitation of natural resources, excessive deforestation, and over-reclamation of land caused by population expansion are the main reasons for the frequent occurrence of sandstorms.

Forests are the "cradle of humanity". Our ancestors were born, grew up in the forest, and finally walked out of the forest. Forests are the "lungs of the earth".

The green leaves carry out photosynthesis, inhale carbon dioxide and release oxygen; The oxygen in the air is 60 ** in the forest. Forests are a "paradise for wildlife". More than half of the world's more than 5.3 million species of plants and animals are in forests.

Forests are the "general dispatch room" of nature's ecological balance. It prevents wind and fixes sand, conserves water sources, maintains water and soil, purifies the air, reduces noise, beautifies the environment, regulates the climate, prevents and fights disasters, and it is the main body of terrestrial ecology. Forests are a huge "reservoir of resources".

It provides humans with a variety of wood, dried and fresh fruits, woody grains and oils, wild animals, Chinese herbs and other forest by-products. More than $400 billion is created annually in global forest products. Forests are also the originator of coal, natural monitors, natural epidemic prevention officers, green sentinels for alarms, natural barriers for soldiers, and beauticians of nature......In short, forests nurture human beings, and their ecological and social benefits far outweigh their own economic benefits.

If human beings want to survive better for a long time, they cannot live without forests. March 21 is World Forestry Day. Let's weave more green and protect our homeland.
