"Able to swallow and spit out"of the forest.

Forests play a very important role in conserving water sources, conserving water and soil, and preventing floods and droughts. According to expert estimates, a forest with an area of 100,000 acres is equivalent to a reservoir of 2 million cubic meters, which is just as the agricultural proverb says"Planting more trees on the mountain is equivalent to building a reservoir.

It can swallow when it rains a lot, and it can spit out when it rains less. "forests are known for this special"Throughput"function is called by scientists"Water swallow and rain spitter"。

Speaking of the forest, that's a lot. In addition to providing wood and many kinds of raw materials for production and life for human beings, it also has outstanding contributions in maintaining the ecological environment"Able to swallow and spit out"The special function that gave birth to human beings. Because at the beginning of the formation of the earth, the atmosphere had a high level of carbon dioxide, very little oxygen, and high temperatures, and it was difficult for living things to survive.

About 400 million years ago, advanced plants from the sea landed and forests were created on land. Forests slowly absorb carbon dioxide from the atmosphere, and at the same time exhale fresh oxygen and regulate the temperature, which has the conditions for human survival, and finally there are human beings on the earth. So scientists also call the forest is"Carbon swallowing oxygen machine"。

Forests are the main body of the earth's ecosystem, the general dispatch room of nature, and the green lungs of the earth. Forests maintain the earth's ecological environment"Able to swallow and spit out"A special feature that cannot be replaced by any other object. Therefore, we must attach great importance to afforestation and protect forests.

At present, it is worth everyone's attention that the green lungs of the planet are shrinking. In the last 200 years, more than one-third of the planet's forests have been harvested and destroyed. On the other hand, carbon dioxide emissions are increasing dramatically due to the increase in the amount of burning on the planet.

The trade-off has led to a sharp deterioration of the earth's ecological environment, which is mainly manifested in global warming. Global warming has a huge impact on human production and life, and even threatens human survival. As a result of global warming, water evaporation accelerates, altering the circulation of air currents and exacerbating climate change, which can lead to heat waves, hurricanes, torrential rains, floods and droughts.

To make this for the earth"Able to swallow and spit out"In order to improve the ecological environment, curb global warming, and reduce natural disasters such as floods and droughts, we should vigorously plant trees and make every barren mountain green.
