Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase in human population continues at the present rate, there may be much greater harm. Some scientists speak of the increase in numbers of people as“population pollution”.About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930, the population was two billion. It was three and a half billion by 1980. It doubled by the year 2000. If the population continues to grow at the same rate, there would be 25 billion people in the world a hundred years from now!Man has been using the earth’s resources more and more rapidly over the years. Some of them are almost gone. Now many people believe that man’s greatest problem is how to control the growth of his own population. The materials in the world will not support the human population, in time to come, if the present rate of increase continues. Already there is overcrowding in the cities and hunger in some countries. Can man’s rate

Why don’t birds get lost in their long migratory flights? Scientists have been puzzled over this question for many years. Now they’re beginning to fill in the blanks.Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly at night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the star in their long-distance flights.One such bird---a warbler(鸣禽)---had spent its lifetime in a cage and never flown under the natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight.Scientists think that warbler, when flying in daylight, use the sun for guidance. But the stars are apparently their principal means of navigation. What
