Namgyal carries some necessary equipment along with him while working on the Xizang plateau(高原)— a pair of gloves，a garbage clip(夹子)and bags. With the spring mountain climbing activity having already begun in this area，he is very busy.
To keep the plateau clean，lots of people of the area have taken the jobs to protect the environment. The yearly subsidy(补助) for them is 3，500 yuan a year.
Namgyal said he was pleased with the policy of providing the job to local residents. The job has helped keep nature clean and increase the income(收入) for his family.
In the past，clean up activity began only during summer near Qomolangma. Since 2016，it has been done regularly all year round.
“With tourism development，I hope more garbage bags would be given out to tourists and more dustbins placed along roads，” said Namgyal. He performs this task along with his team seven to eight times every month.
More people help collect waste during the spring climbing season. Locals clean the areas between the height of 5，200 and 6，500 meters while special workers clean the areas above 6，500 meters. Climbers produce the waste above 5，200 meters while locals and tourists produce the rubbish at lower areas. The collected waste mainly includes drink bottles，plastic bags，food packages，old tents and so on.
With the help of Namgyal and his team，the plateau stays clean and tidy.

The world uses about a thousand million tons of water a day.
Water is a human right and everyone should have their share. Yet more than 700 million people around the world have trouble getting clean，safe water.
Treating wastewater is a good way to provide fresh water for us. And it also helps the environment by keeping waste out of rivers and oceans. 80％ of wastewater around the world is not treated at all，and it is running into oceans. But now we have got the technology to treat and reuse the wastewater.
While 71％ of our planet is covered with water，only little is fresh water—that comes from rivers，lakes，ice and snow. The rest，98％ of the water，is in seas and oceans. It is too salty to drink. Then desalination(海水淡化) businesses come in. More than 19，000 factories have been built around the world，mostly in coastal countries.
They process more than 92 million tons of water every day. But the technology they use requires a lot of energy.
Scientists are working to create a less costly technology. They want to produce 20 times more clean water and make sure everyone has enough. But for now，the world still faces each day with not having enough water for everyone.
