He has wasted the earth’s natural resources with no【C9】________for the future, and has thought out the most devastating ways of killing his fellow men and every other sort of life at the same time.
Since man has done so much【C10】________, it is【C11】________to man to try to put matters right—if it is not already too【C12】________.If there is to be any remedy for our ills, that remedy ultimately lies in the hands of the【C13】________, and the sooner they start doing something about it, the【C14】________.
One of the main【C15】________of the earth’s troubles is that the world is overpopulated and that this overpopulation is growing【C16】________an ever-increasing rate. At the same time we are【C17】________up our natural resources—fuels and mineral ores—at an ever-increasing speed with no hope of replacing them. For many years the earth has been unable to【C18】________enough food for these rapidly expanding populations and the position is steadily deteriorating【C19】________the fertility of some of our richest soils has been lost and vast areas that were【C20】________fertile lands have turned into barren deserts.
