Modern man has cleared the forests for farmland and for wood,and has also carelessly burned them. More than that,though,he has also interfered (干涉) with the invisible bonds between the living things in the forests. There are many examples of this kind of destruction. The harmfulness of man’s interference can be seen in what happened many years ago in the forest of the Kaibab plateau (凯亚巴布高原) of northern Arizona. Man tried to improve on the natural web of forest life and destroyed it instead.

The Kaibab had a storybook forest of largesized pine,Douglas fir,white fir,blue and Engelmann spruce. In 1882 a visitor noted,"We,who ... have wandered through its forests and parks,have come to regard it as the most enchanting region it has ever been our privilege (特权) to visit."This was also the living place of the Rocky Mountain mule deer. Indians hunted there every autumn to gather meat and skins. The forest also had mountain lions,timber wolves and bobcats that kept the deer from multiplying too rapidly.

Then,in 1906,President Theodore Roosevelt made the Kaibab a national game preserve. Deer hunting was forbidden. Government hunters started killing off the deer’s enemies. In 25 years’ time,6,250 mountain lions,wolves and bobcats were killed. Before the program,there were about 4,000 deer in the Kaibab,by 1924,there were about 100,000.

The deer ate every leaf and twig they could reach. But there was not nearly enough food. Hunting of deer was permitted again. This caused a slight decrease in the deer herd (鹿群)，but a far greater loss resulted from starvation (饥饿) and disease. Some 60 percent of the deer herd died in two winters. By 1930 the herd had dropped to 20,000 animals. By 1942 it was down to 8,000.

Long bus rides are like television shows. They have a beginning,a middle,and an endwith commercials (商业广告) thrown in every three or four minutes. The commercials are unavoidable. They happen whether you want them or not. Every couple of minutes a billboard glides by outside the bus window. "Buy Super Clean Toothpaste.""Drink Good Wet Root Beer.""Fill up with Pacific Gas."Only if you sleep,which is equal to turning the television set off,are you spared the unending cry of "You Need It! Buy It Now!"

The beginning of the ride is comfortable and somewhat exciting,even if you’ve traveled that way before. Usually some things have changednew houses,new buildings,sometimes even a new road. The bus driver has a style of driving and it’s fun to try to figure it out the first hour or so. If the driver is particularly reckless (鲁莽的) or daring,the ride can be as thrilling (惊心动魄的) as a suspense story. Will the driver pass the truck in time? Will the driver move into the right?or the left?hand lane? After a while,of course,the excitement dies down. Sleeping for a while helps pass the middle hours of the ride. Food always makes bus rides more interesting. But you’ve got to be careful of what kind of food you eat. Too much salty food can make you very thirsty between stops.

The end of the ride is somewhat like the beginning. You know it will soon be over and there’s a kind of expectation and excitement in that. The seat of course,has become harder as the hours have passed. By now you’ve sat with your legs crossed,with your hands in your lap,with your hands on the armrestseven with your hands crossed behind your head. The end comes just at no more ways to sit.
