Passage #3         Most people hate spiders. But few consider that spiders are intelligent, inventive and good friends to people.Spiders have highly developed nervous systems. Their brains are capable of remembering, and they are remarkable engineers. They can be found living anywhere from 22,000 feet above sea level, on Mount Everest, to 2,000 feet below the earth's surface, in caves.         The silk that spiders spin for their webs has a stretching strength superior to most flexible products made by people. These webs have been known to entangle and hold animals as large as mice. The bola spider, instead of making a web, constructs a silken trapeze, which hangs from branches or twigs. It attaches a globule of sticky silk to the end of the trapeze and casts it out at passing insects. Any insect that gets stuck to the swinging ball becomes the spider's next meal.         One Eurasian species of spider actually travels underwater by carrying a tiny bubble of air with it. Its home is a cozy diving bell constructed from a tightly woven sheet of silk, filled with air bubbles.         Many scientists feel that without the spiders, human life would be in danger. You see, most of a spider's energies are devoted to catching and eating insects. Without spiders, insects would multiply and cover the earth, destroying the vegetation. It has been estimated that each year spiders in England destroy an amount of insects equal in weight to the human population of that country!
