During the summer holiday£¬ my family came to Xizang to observeTibetanantelopes. There£¬ with binoculars£¬ we madeout a herd of graceful animals on the plain and were struck by their beauty and speed. Tibetan antelopes can run at an average speed of 80 km/h. At the same time£¬ I was remindedof the danger they were in. They were huntedillegally for profits. Especially in the 1980s and 1990s£¬ not only were they shot by hunters£¬ but also their living spaces were becoming smaller dueto the construction of roads and railways£¬ which concernedpeople very much. It’s difficult for them to adaptto the changes. Their population was reduced sharply. Luckily£¬ the authorities were awareof the situation£¬ and took effectivemeasures to prevent this species from extinction. The reserve protecting their habitats was set up and volunteers watched them overdayandnight to keep them safe from attacks. Finally£¬ their population has recoveredand they have been removed from the endangered species list. However£¬ the government didn’t intend to give up the protection programmes. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.
