China is striving to build an ecological civilization. One of its efforts in this realm is to repair damaged environments, and restore the beauty of nature.

Since logging ended in the country, wildlife has had the opportunity to flourish again.

In the Greater Khingan Mountains of northeast China, the Ewenki people witnessed the fate of the last group of reindeer in China.

According to Fan Suo, a local Ewenki resident, "there used to be thousands of reindeers" when she was young, then the number shrunk to the hundreds, rising again when the reindeers became well protected.

The needs of the people are being respected as well. Instead of overusing natural resources, many local people can now live off of tourism.

In order to help the environment recover, a company in Inner Mongolia has invested millions in grassland restoration. Guo Jianjun, the vice general manager of M Grass, has introduced big data as part of the effort to restore the grass land: "We are using big data to help us in our work, so that when you click on one place on the map, and it will tell you how the hydrology and weather conditions there are, and what kinds of plants and methods you should use for ecological restoration."

Authorities, especially local forestry bureaus, are backing such efforts, which have made prominent achievements in biodiversity and land preservation in regions near Beijing and Inner Mongolia.
