Are forests really the lungs of the earth? Are forests the lungs of the earth ?

In the past, when we said that forests are the lungs of the earth, the starting point was that forests produce a lot of oxygen, just as human lungs absorb oxygen to the body to bring oxygen to the earth system. The idea that the ocean is the lungs of the earth is that the ocean is the largest carbon sink on the planet, absorbing a quarter of the carbon dioxide produced by human activities. In the context of global warming, there is nothing wrong with saying this.

Of course, forests are also very important carbon sinks, and it may be said that forests produce about the same amount of oxygen as they consume (I'm not a professional who doesn't understand this), but the carbon absorbed by trees is definitely greater than the emissions during their lifetime. Otherwise, how can trees grow taller? It's not all the result of carbon sequestration.

After all, the lungs of the earth are also a metaphor. You can say that a child's face is red like an apple, or you can say something else that looks like an apple, right? In short, we should recognize the importance of oceans and forests in the earth system, and then try to protect them as much as possible.

Forests are the guardians of nature and the pillars of ecological balance. It can maintain the balance of carbon dioxide and oxygen in the air, and can also remove toxic and harmful gases in the air, so it is called the "lungs of the earth".Oxygen in the atmosphere plays an extremely important role in living things.

A person can go days without eating or drinking, but he cannot stop breathing for a moment. On Earth, the vast majority of oxygen is produced by green plants in forests. When green plants photosynthesize, they can absorb carbon dioxide and exhale oxygen.

Of course, green plants also have to respire, but when exposed to sunlight, their photosynthesis is about 20 times greater than that of respiration. For this reason, green plants are called "natural manufacturing plants" for oxygenTrees absorb large amounts of carbon dioxide through photosynthesis.

Forests maintain the balance of carbon dioxide and oxygen in the air, as well as remove toxic and harmful gases from the air, and are known as the "lungs of the earth". Oxygen in the atmosphere is extremely important for the survival of living things. You can go days without eating or drinking, but you can't stop breathing for a moment.

The vast majority of the Earth's oxygen is provided by the greenery of forests. During photosynthesis, green plants inhale carbon dioxide and exhale oxygen. Of course, green plants also need to breathe, but their photosynthesis under sunlight is about 20 times that of respiration.

Greenery has thus become a "natural manufacturing plant" for oxygen. Forests have a strong effect on purifying the atmosphere. Plants in forests can effectively remove harmful gases such as sulfur dioxide, hydrogen fluoride, and chlorine.

All the leaves of 1 acre of forest will have an area as large as 75 acres of land. In addition, there are many fluffy potatoes on the leaves, and the leaves can also secrete mucus and oil, so that various pollutants in the air can be intercepted, filtered and adsorbed by the forest. Forests are truly the "lungs of the earth".

Without the forest, all living things will have difficulty breathing and will not be able to survive.

On August 23, according to foreign ** reports, the lungs of the earth, the forest, is burning at an unprecedented rate, and the smoke has even spread to the city 3,000 kilometers away, and thousands of fires are raging in the Amazon rainforest, and the tropical vegetation, trees and the animals that inhabit them have been reduced to ashes. So what are the general causes of the fire in the forest cracked mascot forest?

Why do forests catch fire?

There are three conditions that must be met for a forest fire to occur:

1. Combustibles (including trees, grass and shrubs and other plants) are the material basis for forest fires;

2. Fire danger weather is an important condition for fire;

3. The fire source is the leading factor in the occurrence of forest fires.

A large number of facts show that forest fires can be prevented, combustibles and fire sources can be artificially controlled, and fire danger weather can also be forecasted to prevent.

Why are forests the lungs of the earth?

Forests are the "lungs of the earth", and the plants in the forest photosynthesize, absorb carbon dioxide, release oxygen and other organic matter, and provide fresh air for many animals, including humans. These plants also store water, regulate the climate, and make an indelible contribution to the balance of the ecological environment. So it's no wonder that some scholars refer to it as the "lungs of the earth" or the "green treasure trove".

Wetlands with powerful purification capabilities are known as the "kidneys of the earth".

Easter Island, an isolated island in the southeastern Pacific Ocean, is known as the "navel of the earth".

The Great Rift Valley is the largest land-based fault zone on the earth, and its popularity is comparable to that of the Mariana Trench.

The forest is called the empty space that contains the earth's bucket and amuses the lungs. （）

a.That's right. b.Mistake.

Correct Answer: a

In addition, forests can also provide a place for recreation and recreation for humans. The natural landscapes and wildlife in the forest attract a large number of tourists to see and tour. This not only provides a place for people to relax, but also promotes the development of tourism and brings benefits to the local economy.

The forest has a very far-reaching effect on human beings. Forests can not only provide the wood, paper, medicine, food, etc., but also the ecosystem services we need. For example, forests can purify the air, protect water sources, prevent flooding and soil erosion, and more.

Forests also have an important impact on the water cycle and water quality conservation. Plants in forests disperse water into the air through transpiration, forming clouds and rainfall, which in turn maintain the water cycle on Earth. In addition, forests can also filter water and purify polluted water sources.

In addition, forests can also provide a place for recreation and recreation for humans. The natural landscapes and wildlife in the forest attract a large number of tourists to see and tour. This not only provides a place for people to relax, but also promotes the development of tourism and brings benefits to the local economy.

The rapid impact of forests on ecosystems.

The impact of forests on ecosystems.

Forests The lungs of the earth, through the photosynthesis of green plants, 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. So, as 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 humans a clean living environment. The lungs of the earth mainly emphasize that green plants can play a role in purifying the air through photosynthesis, whether it is a forest or a tropical rainforest.
