Over-populationists
present assumptions and deeply flawed arguments which ultimately set
into motion a number of draconian measures and authoritarian
policies. For too many environmentalists the common enemy of humanity
is mankind itself.
Carrying
capacity (some use the term ecological/carbon footprint) refers to
the number of individuals who can be supported in a given bounded
area within natural resource limits, and without degrading the
natural social, cultural and economic environment for present and
future generations. The carrying capacity for any given area is not
fixed. It can be altered such as by improved technology. It is very
difficult to calculate human carrying capacity. Humans are a complex
species with elaborate socuial relationships. We do not reproduce,
consume resources, and interact with our living environment
uniformly. Carrying capacity is a function of the number of people,
the amount of resources each person consumes and the ability of the
earth to process all the wastes produced. Sustainability is about
finding the balance point among population, consumption, and waste
assimilation.
Humans
have become one of the world’s only global species by mastering
technology. No species has altered the Earth’s natural landscape
the way humans have. Time and time again, the human species has
overcome scarcity, such as availability of food that limited our
population. Much of the world is inadequately fed despite the
existence of sufficient resources to provide food in abundance, This
is not because of overpopulation or some natural calamity but because
of the capitalist system of production for profit. That the natural
resources of the Earth and the knowledge and technology can provide
an abundance of foodstuffs is a well-established fact.
The
resources of the world can provide not only for the whole human
numbers as it now is, but also for any conceivable expansion in the
population which is likely to occur. Population forecasts can be
said to be at best informed guesses, and as consumption under
capitalism depends upon the vagaries of the market and the extent to
which such competition results in physical conflict, such an estimate
can only be very tentative. Nevertheless increases in consumption are
historically obvious and present trends have at times caused concern
about the ability to meet future needs. Currently food production is
believed sufficient to feed 25 billion people and
growing.
The issue is that in the developing world some 60 percent of
production never makes it to the table. Developed nations cut this
figure to 30 percent primarily through refrigeration.
To
end global poverty we're going to have to carrying on making the best
use of the earth's raw materials. Like most things, there's a trade
off.
How
many times have we heard that we are "using up", "running
out" , "reaching the limits" of the world's resources
and are "exceeding the carrying capacity" of the planet's
ability to bear a bigger population? Mankind's ingenuity and
imagination should make us optimistic about the future as it will
spawn and innovative opportunities and arrangements of resources
which create and generally improve the human condition. Instead of
the slogan “Power to the People,” too many in the
environmentalist movement carry placards declaring “People
Pollute.”
