it seems the curse of modern man continually to confront new possibilities of self-destruction. he emerged from world war ⅱ, armed with nuclear power to obliterate all human life. his population has since grown at a rate that could threaten disaster on a global scale. and now he has come face to face with a new man-made peril, the poisoning of his natural environment with noxious doses of chemicals, garbage, fumes, noise, sewage, heat, ugliness and urban overcrowding. nearly unnoticed, the scourge of pollution has already spread so far that a few scientists say only a drastic cure can prevent devastation, as thorough as that of nuclear holocaust. every nation, large and small, is confronted with environmental hazards. and thus conservation of the environment seems to be the chief task of this decade-and perhaps of the rest of the century. man has had his age of exploration, and proved himself a master at discovering the riches of his planet. he has moved on to an age of exploitation, and demonstrated great skill in putting those riches to use. now the time is long overdue for an age of conservation to begin. the battle against pollution must begin now or it will be too late.
