Why is the Qinghai-Tibet Plateau called "the roof of the world"?

First, because the Qinghai-Tibet Plateau is very high above sea level, it is called the world's three poles together with the North and South poles. Second, because the Qinghai-Tibet Plateau has a great influence on the climate, especially for China, it is well-deserved to be called the third-class in the world in terms of importance.

As we all know, the average altitude of the Qinghai-Tibet Plateau can reach more than 4 thousand meters, and its huge terrain makes the Qinghai-Tibet Plateau connect several provinces at the same time, which has a certain impact on the climate in many parts of China.

For a simple example, without the existence of the Qinghai-Tibet Plateau, the summer monsoon from the south might reach a position farther north, instead of bypassing the Qinghai-Tibet Plateau and transporting it to the Jianghuai area. In winter, the cold air in the north can directly penetrate into the south, which has a certain impact on the weather and climate in the south.

Then in this case, it will change the existing climate environment in the north and south to a certain extent. At the same time, many studies have shown that the snow in the Qinghai-Tibet Plateau, like the snow in the polar regions, will have an impact on many climate phenomena in China. From this perspective, the Qinghai-Tibet Plateau is as important as the North and South Poles, so it is called the roof of the world.

There is also a saying that because the Qinghai-Tibet Plateau is extremely high above sea level, the oxygen on it is very thin. But it is precisely because of this that many explorers are attracted to take risks. Probably because climbing the Qinghai-Tibet Plateau is more challenging, so everyone uses it? Extreme? This word represents a feature of the Qinghai-Tibet Plateau. But at present, the Qinghai-Tibet Plateau is not allowed to climb easily because of protection.

How can I put it? In fact, at present, the snow and various environments on the Qinghai-Tibet Plateau are still very severe. If we continue to destroy the environment or pay no attention to climate change, we don't know what the Qinghai-Tibet Plateau will look like in the future. I think that for a better future, we should still take some actions to make the Qinghai-Tibet Plateau less damaged.
