Had an estimate also been made of the microscopic population, it might have ranged up to two billion bacteria and many millions of fungi, protozoa and algae — in a mere teaspoonful of soiL" The chrysalids of butterflies linger here too, folded, rigid, and dreamless.
Page 16 - ... methods to control pests. This principle of preventative conservation needs to be applied promptly to all forms of air, water, and soil pollution at the source. In the long run, this kind of preventative conservation is much less expensive than restorative conservation.

Page 4 - The whole system seemed to have a kind of comfortable stability. Looking at an astronaut's view of the earth, we begin to realize that the earth is actually not so large at all, and that the stability applies only to our time period, which is infinitely small compared to the time scale of geological and evolutionary happenings. A continuous flow of events...
Page 4 - A continuous flow of events led from the origin of life some two to three billion years ago to the elaborate structures that we represent. For evolutionary processes, changes in the environment were essential ; however, for the continuation of an evolved species, the constancy of the environment was of great importance. Even small changes in the environment will eventually lead to the disappearance of a species, or its replacement by others more suitable to new conditions.
