Description

It was only during the decade of the 1960's that terms such as "water and air pollution," "protection of the environment," and "ecology" became household words. Prior to that time, these terms would either pass unrecognized by the average citizen, or at most, would convey hazy ideas to his mind. Since then mankind has been bombarded by the media (newspapers, radio, television), with the dreadful idea that humanity is effectively working for its self-destruction through the systematic process of pollution of the environment, for the sake of achieving material progress. In some cases, people have been aroused nearly to a state of mass hysteria. Although pollution is a serious problem, and it is, of course, desirable that the citizenry be concerned about it, it is questionable that "mass hysteria" is in any way justifiable. The instinct of preservation of the species is a very basic driving force of humanity, and man is equipped to correct the deterioration of his environment before it is too late. In fact, pollution control is not an exceedingly difficult technical problem as compared to more complex ones which have been successfully solved in this decade, such as the manned exploration of the moon. Essentially, the basic technical knowledge required to cope with pollution is already available to man, and as long as he is willing to pay a relatively reasonable price tag, the nightmare of self-destruction via pollution will never become a reality. Indeed, much higher price tags are being paid by humanity for development and maintenance of the war-making machinery.
