The air is thin and we have to rest several times on the shore hike from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain in front of us, we can just make out a herd of graceful animals. This is why we stay here.

Tibetan antelopes live mainly on the plains of Xizang. Watching them move slowly across the green grass, I'm struck by their beauty. I'm also reminded of the danger they are in. They are being hunted illegally for their valuable fur.

My guide is Zhaxi, a villager from Changtang. He works at the Changtang National Nature Reserve. The reserve is a safe place for the animals and plants of northwestern Xizang. To Zhaxi, protecting the wildlife is a way of life. “We're not trying to save the animals,” he says. “Actually, we're trying to save ourselves.”

In the 1980s and 1990s the population of Tibetan antelopes dropped by more than 50 percent. Hunters were shooting antelopes to make money. Their living places were becoming smaller as new roads and railways were built.

In order to save Tibetan antelopes, the Chinese government placed them under national protection. Zhaxi and volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.

The measures were effective. The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the endangered species list. The government, however, does not intend to stop the protection program since the threat to the Tibetan antelope has not yet disappeared. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.
