In 1990 a report was published about what the earth might be like 20 years from then on. 71 According to the report,the picture of the earth in the year 2010 is not a pleasant one. 72 The population could be as large as 6300 million,almost 2150 million more than in 1985.More people would move into cities ,especially cities in developing countries.Cities like Cairo and Jakarta probably would each have 15 million by then.
73 Farmers will grow 90% more food than they did in 1985,but most of the increase would be in countries that already produce enough food for their people. 74 Poor farming ways are destroying large areas of crop land,changing farms into deserts.More farmland is lost as cities become larger and more houses are built.Air pollution will get worse as industrial countries burn more coal and oil.Many of the world's forests could disappear as more and more trees are cut down.Energy will continue to be a serious problem. 75 They only workde out the situation that exists today.By changing the situation,by settling the problems,the picture can be changed.There is still time for the nations of the world to work out a plan of action.But they warned that waiting too long to make de cisions would greatly reduce the chances of success.
