We have converted woodlands and prairies to farmland virtually
all over the globe. Our cities, suburbs and malls have paved
over natural communities, and pollution and overfishing are
rapidly destroying our rivers, lakes and oceans. As these
ecosystems go down, we are losing perhaps 30,000 species of
animals and plants a year, out of perhaps 10 million total
species, even though we still deeply rely on at least 40,000
species for food, shelter, clothing and fuel. We rely on natural
products to replenish genetic diversity in our crops and to
produce new medicines. We rely on pristine ecosystems to
replenish oxygen, regulate water cycles, control erosion, cycle
essential nutrients and restock critical fisheries. We still
need these things to sustain life - our life. The irony is that
our rampant success in living outside the world's ecosystems has
put them all, and thus ourselves, in jeopardy.
The tide is running back toward Malthus. We are emerging from a
10,000-year vacation from nature still not fully realizing that
our own survival hinges on reducing the damage we do to Earth's
natural systems. We may not drive ourselves to the complete
oblivion of biological extinction, but I fear that the Malthusian
specters of famine, warfare and disease will rise in the
comparatively short run (the next few centuries), coupled with an
accelerating loss of human cultural diversity and, ultimately,
quality of life.
Unless. We can, I think, find the inner will to wake up to our
current situation, to see the grimmer outlook around the corner
and to choose to do something about it. We can stabilize our
numbers and temper our patterns of consumption. We can work to
stem the tide of ecosystem destruction and species loss. We can,
in short, see ourselves for what we have become: the first global
economic entity, a fascinating state arrived at through no end of
cleverness but a state that is ultimately limited by the health
and productivity of the natural system in which we live. We can,
if we choose to do so, prove Malthus' direst prognostications
wrong.
Niles Eldredge is a paleontologist at the American Museum of
Natural History. His book "The Triumph of Evolution" is due out
early next year
