The settlers also brought in their Old World fears and superstitions concerning predators. Whether preying (捕食) on livestock or not, predators were shot on sight. This attitude continues to this day for coyotes, eagles, foxes, mountain lions, and bobcats, and is largely responsible for placing the eastern timber wolf, grizzly bear, and bald eagle on the endangered species list.

　　Yet every animal, including the predator, has its place in nature's grand design. Predators help maintain the health of their prey species by eliminating the diseased, young, old and injured. Predators like the mountain lion and the wolf help to keep the deer herds healthy. Occasional loss of livestock must be weighed against the good these animals do in maintaining the balance of nature.

　　No one knows exactly how many disabled people there are in the world, but 11 suggest the figure is over 450 million. The number of disabled people in

　　India 12 is probably more than double the total population of Canada.

　　In the United Kingdom, about one in ten people have some disability. Disability is not just something that happens to other people: as we get older, many of us will become less 13 , hard of hearing or have failing eyesight.

　　Disablement can take many forms and occur at any time of life. Some people are born with disabilities. Many others become disabled as they get older. There are many 14 disabling diseases. The longer time goes on, the worse they become. Some people are disabled in accidents. Many others may have a period of disability in the form of a mental illness. All are affected by people's attitude towards them.

　　Disabled people face many 15 barriers. Next time you go shopping or to work or to visit friends, imagine how you would 16 if you could not get up steps, or on to buses and trains. How would you cope if you could not see where you were going or could not hear the traffic? But there are other barriers; 17 can be even harder to break down and ignorance 18 represents by far the greatest barrier of all. It is almost impossible for the able-bodied to fully appreciate what the severely disabled go through, so it is important to 19 attention to these barriers and show that it is the individual person and their ability, not their disability, which 20
