Hope and faith in the necessity of preserving natural conditions..."part of the national heritage."
"…This matter an unprecedented urgency." (1988)
"Overall, we are locked into a race. We must hurry to acquire the knowledge on which a wise policy of conservation and development can be based for centuries to come."

"Climb into the tangle of fallen vegetation, tear away
pieces of rotting bark, roll over logs, and you will see these creatures
teeming everywhere. As the pioneer vegetation grows denser, the deepening
shade and the higher humidity again favor old forest species, and their
saplings sprout and grow. Within a hundred years the gap specialists will
be phased out by competition for light, and the tall storied forest will
close completely over."
"Human demographic success has brought the
world to this crisis of biodiversity.... Our species appropriates between
20 and 40 percent of the solar energy captured in organic material by
land plants. There is no way we can draw upon the resources of the planet
to such a degree without drastically reducing the state of most other
"In the next thirty years, the world would
lose not only half its forest cover but nearly half of the forest species.
"If it is granted that biodiversity is at high risk, what is to be done?
The solution will require cooperation among professions long separated
by academic and practical tradition."
"So we should try to expand reserves from 4.3 percent to 10 percent of
the land surface, to include many of the undisturbed habitats as possible
with priority given to the world's hot spots."
"Because scientists have yet to put names on most kinds of organisms,
and because they entertain only a vague idea of how ecosystems work, it
is reckless to suppose that biodiversity can be diminished indefinitely
without threatening humanity itself. Field studies show that as biodiversity
is reduced, so is the services provided by ecosystems.... These services
are important to human welfare."
"Only in the last moment of human history has the delusion arisen that
people can flourish apart from the rest of the living world."
Wilson's edited works.
"Thus, remarkably, we do not know the true number of species on earth, even to the nearest order of magnitude. My own guess, based on the described flora and fauna and many discussions with entomologists and other specialists is that the absolute number falls between 5 and 30 million."
"In the end,suspect it will come down to a decision of ethics–how we value the natural world in which we evolved and now, increasingly, how we regard our status as individuals."
"Rain forests" are key habitats to protect biological diversity, as are coral reefs and the soil of forests and ocean floors.
"Expansion and stewardship may appear at first to be conflicting goals, but the opposite is true. The depth of the conservation ethic will be measured by the extent to which each of the approaches to nature is used to reshape and reinforce the other. The paradox can be resolved by changing its premise forms more suited to ultimate survival, including the protection of the human spirit."
"Surinam, serene, a living treasure awaiting assay."
