How does human overpopulation impact wildlife?

Question

Hey Yahoo,

I have the following thesis:

Human Population Growth has the most direct impact on Wildlife and Ecosystems.

If you agree, you are PRO this thesis: Research the following support and report (e-mail) your findings to the group by tonight or tomorrow.

If you disagree, you are CON this thesis: Same as above.

Pro support:
Human population competes for resources and space.
Regulate population
Education

Con support:
In China, they have regulated birth rate --research the negative impact of that.
Nations with higher education have a lower birthrate. (Europe + Japan population has a negative rate)
Innovation of new technologies.
Educated people realize they don't need as many resources


What are your thoughts?

Answer 1

Overpopulation is bad for the wildlife because. When they are more people we need more resources and where does the resrouces come from...? The wildlife, we comsume trees, animals and everything between. It is like a big machine just making everything vanish.

Answer 2

hi,
i do believe that human overpopulation has a major impact on wildlife.
due to overpopulation pressure on land increases, this makes it necessary for the people to encroach upon forest areas and clear the forest takin away the shelter and home of wildlife. in the process of clearing the forests wildlife is left shelter less and they start moving towards human inhabitations. this can have two effects
a) loss of life os both man and beast
b)sum animals start relyin on humans feeding the animals and thus lose their survival instincts which are very important for them .
as for the plants that have been cleared these are nourishment for the wild life , also there cud be new species of plants and medicinal herbs that get destroyed due to clearin of forests.
by human overpopulation there is a direct impact on the ecosystem
the whole ecosystem is affected

Answer 3

I am on the Pro side. I agree that Human population competes for resources and space, but I also believe that our government should set aside parcels of land in each state that no one is allowed to rearrange, cultivate, populate, whatever...so the wildlife can survive in natural surroundings.
I definitely am against doing what China does to control the population. It should be every person's right to decide how many children they can support. It might be a good idea for our government to come up with a limit to the number of children that they will support through the welfare system. Say...2 or 3...then after that you are on your own.
Sorry, I didn't mean to get off on a tangent. lol...
Just my thoughts coming through.

Answer 4

It's true the human race does affect the wild life. We take up most of the land, we are growing so much and with that comes building more housing and freeways, taking their natural habitat. When humans see a wild tiger or what not they assume it's their to hurt us (well yeah) we invaded their space. Funny to say. I have a mother bird nesting right before my eyes, so I try to keep it as quiet as possible when I'm home.

Answer 5

save the animals- more people mean new house, buissnsses roads ..... and less natrual living spots for animals. Sure some have learned how to live in cities. How are we ever going to find the plant that could be a medical breakthough or save endangered animal and plants if we take a way were they live/grow? Yes proper eduacation is a way to teach everyone, espicaly kids, ways to use less, recycle, that we need the animals and plants to keep ecosystem in balance ......

Answer 6

I our area, the towns and even the cities are being filled up with deer, because of the housing boom. We have a huge deer population around here. It's become a real problem.

Answer 7

Simple answer - encroachment - as the human species populates it destroys the environment of other species.

Answer 8

OK you asked for it

IS THERE A FINAL SOLUTION?????

In 1998
an American statesman said at a Bilderberg group meeting in Copenhagen that the Agenda demanded a reduction of 60% in the world population.

How this could be achieved was not disclosed
on tends to think of soylent green.¿¿¿¿¿¿¿¿¿¡¡
but many strange things have happened since

It is suspected that controlling factors have been in play already for quite a while .
------------------------------...
Overpopulation is the primary cause of most of the world problems .

Polution,desertification,water shortage ,food shortage ,deforrestation,loss of animal habitat ,you name it

People use and need land,so more and more is being changed to accomodate human growth and devellopment,the necessary flora ,which permits life as we know it, is disappearing.

Eco-systems are being exchanged for desserts , concrete and tar.

An environmentally destructive wave is in motion, caused by expanding populations,and expanding agriculture,And the hunger for energy.

An increase in desserts definately affects the global climate. http://answers.yahoo.com/question/index;...

World population has doubled in the last 50 years exceeding the growth of 4 million years (since we became homo sapiens).
To satisfy the growing demand farmers are cultivating unstable lands , too steep or dry to be sustainable.

Mono cultures ,aided by chemicals Exhaust and pollutes the soil .
Adding to this the effects of overgrazing has resulted in large scale desertification.

Each year billions of tons of topsoil are blown or washed away by storms. Due to desertification ans subsequent erosion.

Arable lands and their farms are lost all over the globe. Many farmers sons abandon farming and head for the cities. The farmers that are left have to feed some 70 million more people than the year before but with less topsoil.

Northern China is drying up, what once were millions of food producing people, are now hungry refugees ,running for their lives from the all consuming dust storms.

This will have a great effect on world food prices when they start buying at what ever cost, to feed their people. And drastically affect the stabilities and control of world governments.

Over the last half century,
Population growth & rising incomes have tripled world grain demand from 640 million tons to 1,855 million

In the near future the global farming community will not be able to feed every body ,food prices will continue to rise.

We are responsible for a lot of Environmental destruction that is indisputable ,With much worse to follow,If the Ethanol Bill goes through .
Humanity will replace most of the indigenous forrests and all of its wild life and bio-diversity of medicinal plants etc ,----for chemically grown monocultures ,that need a lot of irrigation with water that is more needed by the surrounding comunities,and that will be infested with plagues of insects ,that will be combated with pesticides

So a cut in the population would take the pressure of our Natural resources and the need for energy.
------------------------------...
SOLUTIONS
But how do we ethically control overpopulation?
In many cultures the number of sons determines the mans status or security in old age.

So it is reasonable to assume that unethical methods can be expected.

Population control in the past and present.

War (past .present and future)
Natures way disease(today,past and future)
Manufactured disease(suspected today)
cures that kill(suspected today)
Poisoned consumer goods (suspected today)
making children infertile or gay,by raising the PH level in drinking water or even drinks (suspected today)
Birth control,(in the past the Olmecs women ate yams to make them infertile,today we have several methods but most reach only the educated ,

I handed out condoms to an native Mazatecca comunity in Oaxaca ,and the church retrieved them all )
Education on birth control(not enough,again the poor regions are excluded )
laws that limit childbirth per family(China)

A possible fanatic future viewpoint brought on by the instinct for survival could be to bring back human sacrifice ,the gods would be over the moon ,the by products could fertilize some of the millions of hectares that modern agriculture has destroyed with its chemicals.

Pressure would be lifted of the coming potable water shortage and Food production.

And with all the full moons we got during the year ,it would have a marked effect on the population growth .
------------------------------...
The Americans manauvering for a nuclear war is also suspicious,this would archieve the 60 % in a flash
------------------------------...

But even if we did any or all of that we would not stop Global warming,the Sun is also in on the act
Humanity with all its destructive powers even colaborating as one is an insignificant force compared to Nature

But we sure as hell could be more economic and responsible with our behaviour to make what we got, last as long as possible ,whilst we are still here ,

We still need the forests to give us Air,Water ,Soil to grow food with and a climate to make that posible and to make life bearable for us.Not to speak of the absorbsion of harmfull gasses .

And it is silly to contaminate that which we need
Chief Seatle said about 100 years ago that those who live(sleep) in their own trash will die in it .
We should prove him wrong, But so many insist on ,making him right .

Will humanity ever reach sanity ,your guess is as good as mine Source(s) by a friend of the Planet
