Preserving more habitats for China’s giant pandas is providing a giant payoff.1．(save) the giant panda from dying out isn’t just good for the panda, but it’s also good for economy, a new analysis by an international team of scientists shows.

The results,2．(publish) in the magazine Current Biology, stress the economic bene-fits that go hand in hand with environmental protection. Giant pandas are one of the3．(rare) species around the world. But pandas fell on hard times in recent decades, thanks largely4．human encroachment (侵入). In 1980 alone,many habitats5．(destroy) artificially, and in 1990, their habitats covered only 12,340 square kilometers, 6．is a major threat to the pandas in large part because bamboo, their main food source, is so low in nutrients that they must wander a lot of land in order to find and eat enough of it.

Because of this, Chinese officials began making significant efforts to save the panda from 7．(extinct), establishing more reserves and increasing the reserve area three times. Panda numbers8．(gradual) began to recover, hitting 1,596 in 2000 and 1,864 in 2010.

“9．is clear that society’s investment (投资)10．(start) to pay off so far in terms of panda population recovery,” the study authors wrote.
