It has to be said that the work of volunteers can only be done by people who have love and dedication in their hearts.

A few people walked up the clear river and met many tourists along the way. Of course, people here were also warned that they must take away their garbage and not pollute the environment.

But the rules are not always obeyed by everyone. In addition, tens of thousands of tourists punch in at popular scenic spots, there will always be garbage left intentionally or unintentionally.

A few people stop and go, and they really encounter a lot of man-made garbage.

Feng Lanchu's heart is very heavy. "The traffic here is not more developed than that in the mainland. The garbage can not be disposed in time, and it can only be digested by nature. But it takes a long time to digest, and the speed of nature's digestion of garbage can't keep up with the speed of human production of garbage. We should know that the glacier and snow water here constitute the source of China's rivers, and they set up a solid barrier for the ecosystem of the middle and lower reaches of the Yangtze River, the Yellow River and the Yarlung Zangbo River. If even here is polluted, we will have no water to drink. "

Feng Lanchu's words shocked Jiang Anzhi and Li Yue.

Li Yue's voice is a little hoarse. "Before receiving this program, the director said it was a variety show with the theme of protecting the environment. I thought it was just an ordinary appeal. I didn't expect it was such a solemn thing. "

"Due to the unique natural environment and harsh climate conditions, most of Hoh Xil still belongs to the" no man's land ". The wildlife behavior, vegetation succession, evolution of lakes and rivers, soil development and other natural processes here have not been disturbed by human activities, and still maintain the original natural evolution process. So this is a natural laboratory for people to study the evolution of the alpine natural environment and its impact on the global environment. "

"I don't understand." Li Yue shakes his head honestly. He thinks that his Xueba design will collapse from today.

"To put it simply, there are many endangered animals and plants in our country, and the way to save them may be found in these primitive ecology. That's what Kekexili is so precious, and it's important to protect it. As for endangered species, the disappearance of one species will affect 30 related species, and these 30 species will affect the other 30 related species. The biological chain is closely linked, just like the domino effect. What's the final outcome

"The end of mankind." Jiang Anzhi answered faintly.

Feng Lanchu chuckles "yes. That's why so many people work hard to protect the ecological environment, which is also a way to protect our homes and protect human beings. "

"When Mr. Feng said that, he immediately felt that what we did was very meaningful." Li Yue raised the garbage bag in his hand.

Fenglan chuxiao said that he had a good understanding. She found a white snow mountain behind the yellow rock mountain. She immediately laughed

"Look, Mount Everest."

At the same time, Li Yue turned his head and saw that under the blue sky, a snow-white peak with white clouds, surrounded by mountains, seemed so holy and elegant.

It's far away from them, but it's famous.

"There is a huge glacier under Yuzhu mountain. The melting snow water on it converges into lakes in Hoh Xil. Of course, some of them form the source of big rivers."

"If only I could see it personally." Li Yue sighed. Suddenly he thought of something. He turned to the camera and said, "director, if we can finish the task efficiently these two days, can you take us to yuzhufeng?"

The director said with a big smile, "yes."

Now the three are more energetic.
