Is life today more dangerous than it used to be? It certainly seems that way.With the radiation emitted by our houses，the arsenic(砷)in the water and the toxic rays

coming out of cell phones，it isn't really safe to sleep，drink or talk.

Last week the entire Metro system in Washmgton had to close down because some- one might be blown onto the tracks during a hurricane.This week children in Washing- ton were not allowed to go to school for a whole day because streets were blocked by fallen trees and power 1ines，and traffic lights at some intersections weren't working.A previous generation might have walked around the fallen trees and looked both ways be- fore crossing the street，but the children of this generation clearly live in a much more dangerous world，and we need to protect them.

After Sept.11，2001，thousands of people swore off airplanes and began driving cars.In fact，the odds of being killed in a terrorist incident in 2002 were one in 9 mil- lion.In that same year，the odds of dying in a traffic accident were about one in 7,000.

By taking the precaution of not flying，many people died.

There are some clear psychological explanations for some of this.It's a fact that people fear man-made disasters(terrorism)far more than they fear natural disasters (hurricanes)，and they are more afraid of things they do not control，which is why driv- ing a car does feel safer than flying in an airplane.Also，although I have no proof，I'll hazard a guess that people are disproportionately frightened by things they read about in the newspaper.By contrast，they are disproportionately willing to discount the evidence

of their own experience.If you look around your neighborhood，you’1l notice that the

water is clean—which it wouldn't necessarily have been 100 years ago—and that the food isn’t rotten or stale.

Life is far safer for the average American than it ever has tor j ust about anyboay at any other time in human history—and maybe that explains the ludicrous precautions that city officials and federal bureaucrats and everyone else feels obligated to take nowadavs to satisfy the public's demands.Now that we'Ve eliminated most of the things that

the human race once feared，we've just invented new ones to replace them.

In the summer of 1978 an English farmer was driving his tractor through a field of wheat when he discovered that some of his wheat was lying flat on the ground. The flattened wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. The five circles were in a formation like five dots. During the following years, farmers in England found the strange circles in their fields more and more often. The circles are called "crop circles" because they appear in the fields of grain ？ usually wheat or corn. The grain in the circles lies flat on the ground but is never broken; it continues to grow, and farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. At first, people thought that the circles were ahoax. Probably young people were making them as a joke, or farmers were making them to attract tourists. To prove that the circles were a hoax, people tried to make circles exactly like the ones that farmers had found. They couldn't do it. They couldn't enter a field of grain without leaving tracks, and they couldn't flatten the grain without breaking it. Many people believe that beings from outer space are making the circles to communicate with us from far away and that the crop circles are messages from them. Scientists who have studied the crop circles suggested several possibilities. Some scientists say that a downward rush of wind leads to the formation of the circles - the same downward lash of air that sometimes causes an airplane to crash. Other scientists say that forces within the earth cause the circles to appear. There is one problem with all these scientific explanations: crop circles often appear in formations, like the five-dot formation. It is hard to believe that any natural force could form those.

At first sight, the fate of threatened species might seem a world apart from the economy. Upon closer examination, however, we start to understand the connections between the two. The “good health” of natural systems is a precondition for the “good health” of our social and economic systems. Can one say that a society is thriving when it is exposed to air and water pollution and endures related health problems? Equally, can a society “function” if a large proportion of people are unemployed or cannot make ends meet?

Despite gaps and uncertainties in our understanding, we can see that our world is changing. After 10,000 years of relative stability, the average global temperature is increasing. Although the European Union’s (EU’s) greenhouse gas emissions are declining, fossil fuels release more greenhouse gases into the atmosphere than our land and oceans can absorb. Some regions are more vulnerable to the potential impacts of climate change – and t
