at the ages-old battle between man and his environment. It
considers the signs which indicate that both sides may be los-

polluting, overcrowding, plundering and reshaping his own
habitat into an environmental trap? This Yearbook, like its
forerunners, is addressed to concerned citizens who seek to
turn the environmental tide in favor of both man and Nature.
