Global Overpopulation- Effects and Solutions - Human Overpopulation Powered By Docstoc
					?Each week, we add about a million and half people to our current world population,
which is at 6.8 billion. We have we reached the point many describe as global
overpopulation.

The family of humans, known as the hominids, has populated Earth, according to the
fossil record, for 5 to 6 million years. The hominids transitioned from one genus to
another before our genus, homo, appeared about a million and half to two million
years ago. We transitioned through a number of homo species before our species,
homo sapiens ("sensible humans") emerged about 150,000 years ago.

Over time, we've accumulated people. Two-thousand years ago, our population was at
250 million. In the year 500 A.D., it remained the same. By 1000 A.D., we climbed to
500 million people. We reached 750 million people around 1500 A.D. We hit our first
billion mark in 1800 at which time the Industrial Revolution kicked in. We added
people more rapidly and began to move quickly in the direction of human
overpopulation. Between 1800 and 1900 we added 600 million people. At 1900, we
were at 1.6 billion. By 1960, in 60 short years, we nearly doubled that as we reached 3
billion.

In 1960, we humans had been here about 150,000 years. It took us that long to
accumulate 3 billion people. How long did it take for us to double that number?
Thirty-nine years! In 1999, we reached 6 billion people. It is estimated that we will be
at 9.2 billion by 2050.

The effects of global overpopulation are multiple and ominous. As the result of having
so many people who do not understand our reality and its behavioral demands, we
have created an interrelated web of global environmental problems. We are depleting
our natural resources: our forests, fisheries, range lands, croplands, and plant and
animal species. We are destroying the biological diversity on which evolution thrives
(this is being called the sixth great wave of extinction in the history of life on earth,
different from the others in that it is caused not by external events, but by us).

With powerful new electrical and diesel pumping techniques, we are draining our
aquifers and lowering our water tables. We are systemically polluting our air, water,
and soil, and consequently our food chain. We are depleting the stratospheric ozone
that shields us from harmful ultraviolet radiation. And, we are experiencing symptoms
of global warming: heat waves, devastating droughts, dying forests, accelerated
species extinction, dying coral reefs, melting glaciers, rising sea levels, more frequent
and intense storms, and a more rapid spread of diseases.

With so many of us on a very small and fragile planet, and with the addition of so
many more every week, we can no longer continue to relate to each other, our
environment, ecological systems and biosphere as we have throughout our history.
Nature, which could not care less, will eliminate us. To sustain humanity and advance
our civilization, humankind must travel on a new and far more enlightened track. The
solutions to global overpopulation and other pressing issues can be found at the
