Abstract

A growing concern for the welfare of endangered or threatened plant and animal species has developed during the past few years, coinciding with an awareness of mankind's deleterious influence on the environment. Technological man has altered vast areas of the earth's surface to such an extent that many species have been endangered or made extinct. Transcontinental highways, shopping malls, industrial parks, home sites where they shouldn't be, and huge acreages turned over by the plow for monocultures, have taken a toll on our native vegetation to such an extent that many species have either lost their diversity or have disappeared. There are natural extinction rates, but these have been accelerated by man's activities. And, a sobering thought, extinction is forever.
