Say goodbye to the Mountain Gorilla. Say farewell to the Short Tailed Chinchilla.That’s the conclusion of the United Nations Environment Program’s (UNEP) Third Global Environmental Outlook Report. The report was compiled (编写) for the UN from the work of 1 100 scientists. It predicts the state of the planet in the year 2032 based on the policies and practices of the last 30 years. If these continue, UNEP says, we’re going to be living on a very lonely planet. By 2032, one quarter of the world’s mammal species (哺乳动物种群) will disappear. They will be joined by 12% of the world’s bird species. And according to UNEP, 5 611 species of plants will also be wiped out-but since only 4% of the world’s plant species have been examined in detail, that figure will probably be much higher.UNEP blames a variety of causes, from poverty and overpopulation to pollution, global warming and profit-driven economic and trade policies. But there is some good news. There has been an 85% reduction in the use of chemicals, for instance. And around 10% of the earth’s surface is in protected areas like national parks, five times as much as 30 years ago."We can never know for certain what lies before us," said a UNEP official. "The future is another country. But we can see how our actions or lack of actions might shape the environment and the inhabitants(居民) of this extraordinary blue planet by 2032." A UNEP official said, "The future is another country." Here he implies that"()".
A. We can never do anything for the future
B. We can never know for certain about the future
C. We can see how lack of actions might effect on the inhabitants
D. We can see how our actions might influence the environment
