Quotes by Ecologists

One of the anomalies of modern ecology is the creation of two groups, each of which seems barely aware of the existence of the other. The one studies the human community, almost as if it were a separate entity, and calls its findings sociology, economics and history. The other studies the plant and animal community and comfortably relegates the hodge-podge of politics to the liberal arts. The inevitable fusion of these two lines of thought will, perhaps, constitute the outstanding advance of this century.
Aldo Leopold
The human race has the capacity to render itself extinct unless alternatives are found to the patterns of intraspecific warfare that have dominated civilized history. Ours has long been a predatory species. Living, for humans, depends upon the ability to kill as clearly as it does for lions or wolves. But lions and wolves, like almost all predatory species, normally limit their killing to prey animals, and they are equipped with elaborate ritual precautions to prevent the destruction of their own kind. Humans appear to be unique among predators in their enthusiasm to destroy members of their own species. Perhaps this unusual behavior can be attributed to some genetic deficiency which may lead humans ultimately to join the rest of nature's failures in the biological graveyard of extinction. Or perhaps our willingness to kill ourselves, like so many of our other problems, is something we have devised by misusing our enlarged brains.
Joseph W. Meeker
...trying to predict whether global warming will moderate the next ice age is not only impossible but irrelevant. It doesn't help us get through the next few centuries. And one can only imagine our future, shivering, ice age descendants cursing us for leaving them no fossil fuel to create a global warming "greenhouse" effect when one is really needed.
