It's really nice to see a lot of Tibetan antelopes(藏羚羊)on the green grass. However, (they) population dropped by more than 50 percent during the 1980s and 1990s. To make profits, some people were shooting antelopes. The habitats(栖息地) the beautiful animals lived were becoming smaller as new roads and railways (build).
In order to save this species from extinction, the Chinese government placed it under (nation) protection. Many volunteers watched over the antelopes day and night to keep them safe from attacks. Bridges and gates were added to let the antelopes move (easy)and keep them safe from (car) and trains.
Gradually(逐渐地), the antelope population has recovered and June 2015, the Tibetan antelope was removed from endangered species(物种) list. The government, however, does not intend to stop the protection programmes, since the threats to the Tibetan antelopes have not yet disappeared.
In a word, if we want (save) the planet, we must change our way of life. Only when we learn to exist in peace with nature can we stop (be) a threat to wildlife and to our planet.
