Article: When people get bad toothaches, they often have to eat soft, easily chewed food. When lions get bad toothaches, they eat people? That' s the conclusion of a zoologist at the Field Museum of Natural History in Chicago and a dentist who works on carnivores ., Lions don't normally prey on people. Every once in a while, however, a lion will go on a human-eating diet. The most famous such tragedy happened in 1898, when two lions killed and ate 135 railway workers in prefix = st1 /Kenya. Examining the preserved skulls of the two big cats, zoologist Bruce Patterson and dentist Ellis Neiburger found that both animals had been suffering from several dental and |aw problems. One lion had three missing teeth and a loose, unsteady lower canine that was probably useless. Canines are pointed teeth that hunting animals use for gripping and piercing prey ) .The two lions might have been so badly disabled that they couldn't bite down forcefully, say the researchers. Consequently, the lions might have abandoned their normal, more difficult prey and turned to humans. "Humans are easy preys, " said Patterson. "We're very slow, we don't hear very well, and we don* t see very well in the darkness. " The research calls their idea the Infirmity Theory. It was inspired partly by the work of Jim Corbett, a tiger hunter in Indiain the 1930s. Corbett was regularly called in to hunt tigers that had been dining on Indian villagers. Time after time, Patterson discovered that the killer tigers were suffering from some ill-healthy conditions.

Article: 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 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 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 _ . 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 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 ,but a far greater loss resulted from starvation 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.

Article: One evening after dinner, Mr. and Mrs. Tisich called a family meeting. "We've had to make a difficult decision," Mr. Tisich announced. "You see, your mother has been offered a post as co-director of a television station in Chicago. Unfortunately, the station is not here. After thinking long and hard about it, we've concluded that the right decision is to move to Chicago." Marc looked shocked, while his sister Rachel breathlessly started asking when they'd be moving. "It's surprising, but exciting!" she said. Marc simply said, "We can't go--I can't leave all my friends. I'd rather stay here and live with Tommy Lyons!" The Tisichs hoped that by the time they moved in August, Marc would grow more used to the idea of leaving. However, he showed no signs of accepting the news, refusing to pack his belongings. When the morning of the move arrived, Marc was nowhere to be found. His parents called Tommy Lyon's house, but Mrs. Lyons said she hadn't seen Marc. Mrs. Tisich became increasingly concerned, while her husband felt angry with their son for behaving so irresponsibly. What they didn't know was that Marc had started walking over to Tommy's house, with a faint idea of hiding in Lyons's attic for a few days. But something happened on the way as Marc walked past all the familiar landscape of the neighborhood: the fence that he and his mother painted, the tree that he and his sister used to climb, the park where he and his father often took evening walks together. How much would these mean without his family, who make them special in the first place? Marc didn't take the time to answer that question but instead hurried back to his house, wondering if there were any moving cartons the right size to hold his record collection.
