      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 large sized 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 25years' 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.
