Scientists are currently conducting a study on loblolly pines. The study utilizes a ring of
carbon dioxide generators that surrounds patches of these trees. The purpose of the study is
to determine the effect of an increase of CO2 in the air on these pine trees. So far, they have
noticed that the trees seem to be growing and reproducing much faster than before. They
are also developing more needles - an average of 17% more needles than typical loblolly
pines. At first blush, this looks like a good thing. Trees hold carbon dioxide inside them,
keeping it out of the atmosphere. It appears that the CO2 problem will be self-remedying:
more CO2 produces more trees which absorb the additional CO2. The system appears to be
self-stabilizing. There is a dark-side of course. For one, other species of trees probably
wont enjoy the additional growth spurt. This means that the loblolly pine could spread
quickly, pushing out other species of trees, such as oak or maple. This can change the entire
landscape of an ecosystem ? for example, squirrels and black bear rely on acorns from
hardwood trees. If the loblolly pushes out these trees, the populations of squirrel and black
bear will have to move on or die. Another issue, and the one we can learn a lesson from, is
sustainability. The rapid growth of these trees is using up soil minerals much faster than
they would normally. According to scientists, the trees will eventually run out of nutrients
and fixed nitrogen, and then growth will come to a crashing halt, and may even reverse
itself. So, by using up their fuel in order to create rapid growth, they will eventually
run out of fuel and growth will stop or reverse itself. Does anyone else see a parallel to
our own civilization here? Nature is self-regulating. This is where my fellow liberals and
progressives often get things wrong. Nature does not need man to protect it. Nature does not
care if man abuses it. As our conservative bretheren are fond of pointing out, the Earth has
survived much worse natural disasters than anything Man has been able to throw at it, and
life has always found a way to survive and to thrive. Sure, it can take millions of years, but
it does survive. . . and what is a few million years to a planet that is 4 billion years old?
Conservation is not an end unto itself. Conservation is not necessary to protect the Earth.
No, conservation is necessary to protect and aid Mankind, not nature. Destroying
rainforests, burning fossil fuels, overdeveloping the land. . . all the result of our species
spreading and growing and consuming resources. Nature will correct this. We will run out
of rainforests, we will run out of fossil fuels, and we will run out of developable land. Our
sources of food and clean water will be depleted; our sources of medicine and other critical
products will be depleted. The growth of our species will come to a crashing halt, and will
reverse itself. It will reverse itself back to sustainable levels ? however, the sustainable
level will be much lower then than it is now since we will have used up almost all of what
we need to keep going as a species and as a society. Malthus was the first to predict this. He
showed that, unless something else checks the growth of a species, the species will eventually
crash. Catastrophic disaster will inevitably reduce a species numbers well below the
sustainability level. In other words, if humans dont regulate themselves willingly, nature
will regulate us, and nature is far less selective or merciful about how it accomplishes this.
When we speak of growth now, we are not just talking about growth in numbers, although
that is part of the equation. We are talking mostly about growth in consumption of
resources. Even if our population was stable, our consumption will continue to increase as
the develping world becomes more and more developed. This growth in consumption, like
the growth in numbers, is subject to the same law of Malthus ? if we dont regulate it
ourselves, it will be regulated for us, and it will be regulated by catastrophe rather than
planning. Terry is a Gen-X family guy with 2 step-kids and a loving, supportive wife. He
