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." At the beginning of the passage, "Mountain Gorilla" and "Short Tailed Chinchilla" seem to be some（）

The motor vehicle has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows essentially from uncivil (不文明的) behavior of drivers who refuse to respect the legal and moral rights of others. So the killing on the road may be regarded as a social problem.In fact, the enemies of society on wheels are rather harmless people. Just ordinary people acting carelessly, you might say. But it is a principle both of law and common morality (道德) that carelessness is no excuse when one’s actions could bring death or damage to others. A minority of the killers go even beyond carelessness to total negligence (疏忽).Researchers have estimated that as many as 80 per cent of all automobile accidents are due to the mental condition of the driver. Emotional upsets can distort drivers’ reactions, slow their judgment, and blind them to dangers that might otherwise be evident. The experts warn that it is vital for every driver to make a conscious effort to keep one’s emotions under control.Yet the irresponsibility that accounts for much of the problem is not confined to drivers. Street walkers regularly violate traffic regulations, they are at fault in most vehicle walker accidents; and many cyclists even believe that they are not subject to the basic rules of the road.Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle have been raised both at the point of manufacture and through periodic road- worthiness inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to convince people that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things present a threat to those with whom they share the road. Who are NOT MENTIONED as being responsible for the road accidents（）
