Transcript of Period 7 - Teresa Benites - World Overpopulation
Overpopulation affects almost every aspect of
life, including the earth.
As a continuing and rapid growth of human
population, if the idea of World Overpopulation
is not considered then the animals, the plants, the
fossil fuels, and the environment will deteriorate.
Environmental scientist often conclude that the
biggest problem for the environment is human
overpopulation.

Overpopulation is not a myth, and will grow into
a problem without proper consideration.
Education on World Overpopulation is vital and
could help sustain the environment to live a more
comfortable life.
Overpopulation affects the environment, the
economy, our food production, animal
species, and even ourselves.
Declination of the Mortality Rate.Death rates are dropping and they will continue to do so with the advanced technology and research humans are providing for each other.
Medicine is also big key factor.
Increase of Birth Rates.New discoveries in nutritional science have been able to bring an increase in the fertility rates of human beings. Women also have easier births
since global maternal death rate has dropped 35 percent in the past 30 years (The Lancet).
Emigration.Emigration is also a problem in certain areas, where too many people are coming in and not enough are leaving to balance out the population.
For example, in the United States population [under the current immigration policy] will double this century - practically within the
lifetimes of children born today (US Census).
Lack of Education.If humans were aware of the population, the problems wouldn’t be severe. For example, if every human was taught and given education on
birth control and safe sex, there could be a noticeable decrease in unwanted pregnancies. Every year, there are about 80 million
pregnancies. 40% of the pregnancies; almost half, are unplanned (Hood 2009).

Humans excrete wastes and pollution that flow into water
systems, and animal habitats, polluting water, and killing
wildlife (Derek & Ryan).
Resources that humans need and want are taken away from
the Earth and pollute the air.
Just a single human waste product — greenhouse gas — has
drastically altered the chemistry of the planet’s atmosphere
and oceans, causing global warming and ocean acidification
(Center for Biological Diversity).

As the human population grows, so does the
demand of natural resources, especially in the
developed countries.
One example of the fastest disappearing fossil
fuel is petroleum.
By 2020, petroleum will almost be completely
gone from the world (Aguimbau 2010).

The demand for land has caused deforestation
and caused harm to many animals.
Most biologists agree that humans are in the
midst of the Earth’s sixth mass extinction event.
Because of humans, species of animals are
disappearing about 1,000 times faster than is
typical of the planet’s history.

As humans grow, so does the need of land.
One third of the Earth is land, and only 10% of that 1/3
is suitable for intensive agriculture (arable land).
It is estimated that 400 square miles of arable land can
support one million people.
An estimation states that there is enough land for 15
billion people. However, in the year 2100, it is
estimated that the population will hit 15 billion.

As overpopulation grows, so does the need for food and clean water.
While rapid increases in population spell danger for food levels in the
developing world, so does food waste and meat consumption in the
developed world.
Because of the constant demand on food, new research has been proposed
on manipulating genetics and DNA in food, calling it the “genetic
revolution.”
Water is another problem to face, since only 1% of the water on earth is
drinkable.
Desalinization is expensive and energy consuming and in the US water is
being pumped out of the ground far more rapidly than it can be
replenished.

When there are too many people on a certain
area, the harder it is to get food let alone even
obtain to sell.
While this is going on, the GPD per capita can
drop significantly which forces the government
to rely on foreign debt to feed the people.
When a country is overpopulated, there is a high
rate of unemployment because there just aren’t
enough jobs to support the population.
Sources from Derek and Ryan “Effects of Overpopulation.”
In one specific region that humans are being greatly affected
by overpopulation is China.
China's one child policy was established in 1979 to limit
China's population growth by limiting a couple to have only
one child (Rosenburn 2010).
China’s one child policy, though arguably successful in
curbing population growth, has led to human rights violations
ranging from forced sterilizations, forced abortions and
infanticide (John Taylor 2010).

As humans try and control their population by enforcing fertility laws, a very important concept is education.
Education is the best way to inform and show people awareness of the situations and crisis’s happening to our planet. The awareness and availability of birth control will inevitably drop the unwanted pregnancies.
Practicing cleaner agriculture and industrial technology would greatly help the food production and pollution in the world today.
Overpopulation is not a myth but a serious matter. However, it can be controlled if everybody in the world spread awareness and education about this situation.
