What are the lungs of the earth? Where are the lungs of the earth?

The lungs of the earth refer to forests.

The lungs of the earth refer to forests, and the Amazon rainforest is an outstanding representative of forests, which is widely regarded as the lungs of the earth. The Amazon rainforest covers an area of 70,000 square kilometers, covering eight countries including Brazil, Ecuador and Bolivia, and produces 1 3 percent of the world's oxygen, contributing to the global climate system and ecosystem balance. However, due to the overexploitation and lack of protection awareness in Brazil and other countries, the Amazon rainforest has suffered serious damage, and since the 6s, large areas of forests have been destroyed in the harvesting, resulting in reduced precipitation, dry climate, and increased desertification.

1. It is imperative to protect forests. Biologists have said that forests are the lungs of the earth, but with the destruction of forests by human beings, the ecological environment is deteriorating day by day, the forest area disappears by 20,000 square kilometers per year, and natural disasters are frequent.

Forests are the lungs of the earth, especially tropical rainforests. Tropical rainforests, through the photosynthesis of green plants, can not only convert solar energy to form a variety of organic matter (forests provide 100 million tons of organic matter every year, accounting for 53.3 billion tons of total organic matter production by terrestrial plants).

4%), and relies on photosynthesis to absorb a large amount of carbon dioxide and release oxygen, maintaining the balance of carbon dioxide and oxygen in the atmosphere, purifying the environment, and enabling human beings to continuously obtain fresh air. Therefore, it is figuratively said that "the rainforest is the lungs of the earth". The development of forests and human beings is closely related to the ecological balance of the natural world.

Through the photosynthesis of green plants, forests can not only convert solar energy to form a variety of organic matter, but also absorb a large amount of carbon dioxide and release oxygen through photosynthesis, maintaining the balance of carbon dioxide and oxygen in the atmosphere, purifying the environment, and enabling human beings to continuously obtain fresh air. Therefore, biologists have said, "Forests are the lungs of the earth".

The lungs of the world's earth refer to the Amazon rainforest region of South America.

The lungs of the earth refer to the Amazon rainforest.

Plants can rely on photosynthesis to absorb carbon dioxide while converting it into organic matter and storing it while releasing oxygen, because of this process, green is an important color on earth, and it is one of the foundations of life. The Amazon, with its lush tropical rainforests, is known as the "lungs of the earth".

Amazon rainforest, located in South America, occupies half of the world's rainforests.

Tropical rainforests such as the Amazon in South America.

The lungs of the earth are forests, through the photosynthesis of green plants, not only can convert solar energy to form a variety of organic matter, but also absorb a large amount of carbon dioxide and release oxygen by photosynthesis, maintain the balance of carbon dioxide and oxygen in the atmosphere, purify the environment, and enable human beings to continuously obtain fresh air. Therefore, biologists have said, "Forests are the lungs of the earth". The development of forests and human beings is closely related to the ecological balance of the natural world.

Forests give human beings a clean living environment and a green treasure house, but the destruction of forests by human beings has caused the ecological environment to deteriorate day by day and disasters are frequent. Natural and man-made disasters have reduced the world's forest area from about 8 million square kilometers to 2.8 million square kilometers. Moreover, forest area is still disappearing at a rate of 200,000 square kilometres per year.

How to protect forests:

1. Improve the forest legal system and strengthen forestry management.

To manage forestry well, we must first establish and improve forestry institutions; the second is to strengthen the publicity and education of forestry legal system; the third is to strictly enforce the forest felling plan, felling volume and felling method; Fourth, strict felling approval procedures; Fifth, pay attention to the prevention and control of forest fires and pests and diseases; Sixth, we should use the method of levying a forest resource tax to strengthen forest protection.

2. Rational use of natural forest areas.

The use of forest resources, we must be rational felling, timely renewal after felling, so that the growth of timber and the amount of felling are basically balanced. At the same time, it is necessary to improve the utilization rate and comprehensive utilization rate of wood.

3. Increase the forest coverage rate in phases and regions.

By the end of this century, the forest coverage rate in our country will reach 20 per cent, which should be achieved in phases and in different regions.

4. Create farmland shelterbelts and accelerate the greening of plains.

China should establish farmland shelter forests in northwest and north China as soon as possible, give full play to the role of forest microclimate, and resist natural disasters. Actively promote the construction of agroforestry ecosystems. Increase biological productivity and economic benefits per unit area, while increasing system stability, improving land and environmental conditions, and reducing soil erosion.

The lungs of the earth are forests.

Through the photosynthesis of green plants, forests can not only convert the sun into a variety of organic matter, but also absorb a large amount of carbon dioxide and release oxygen through photosynthesis, maintaining the balance of carbon dioxide and oxygen in the atmosphere, purifying the environment, and enabling human beings to continuously obtain fresh air. For this reason, biologists have called forests the lungs of the earth.

Forest ecosystem is the largest and most important natural ecosystem in the terrestrial ecosystem, which has the functions of regulating climate, conserving water sources, maintaining water and soil, preventing wind, fixing wheels and removing sand, etc., and also maintains the highest species diversity, which can generally be divided into four basic levels: tree layer, shrub layer, herbaceous layer and ground.

Forest resources of various countries:

China is a country with poor forest resources. Compared to some countries with high forest cover, Guyana is 97, Finland is 69, Japan is 68, the United States is 33, and China is only 22, which is lower than the world average of 22. The per capita forest area is only 16 acres per capita, ranking 121st in the world.

Therefore, it is urgent to vigorously plant trees and improve our ecological environment. Forests are the lungs of the earth. The terrible thing is that this "lung" has now been cut off 2 3 due to massive logging.

Protecting forests, saving forests, and expanding forests has become the only way for human beings to protect their own survival and sustainable use.
