Question

When the population grow, how does it effect our environment?

Answer 1

The population growth affects the amount of food we need to produce. It helps if we can grow our own fruit and vegetables and become self sufficient.

It also affects our lifestyle and employment opportunities.

Answer 2

As the human population grows, there is a need for housing and more food.  More land will be cleared and deforested, causing loss of habitat for many animals and a disruption in the equilibrium of the area.  

  As the demand for food increases, more land will have to be cleared for crops, more factories will be built (leading to more emissions of pollutants and toxins), and livestock.

   The demand for meat such as  beef, will cause problems as well. It takes thousands of gallons per cow to raise- and a large amounts of grain and feed.  When a grazing area for the cattle gets depleted, the ground will get dry and barren, the soil that once was able to grow grass is unable to because the porous soil is crushed, inhibiting the abosorbtion of water. This process is known as desertification.

  Finding enough space for all the humans on the Earth poses a very big problem.  Adequate living conditions will be hard to accomodate, especially with the chances of poverty levels increasing.

  Global warming will keep on getting worse, as more vehicles will be bought and more pollution occurs.

  Hope this answered your question!

Answer 3

overpopulation is the primary cause of all the world problems

polution,desertification,water... ,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 or roads.

An environmentally destructive wave is in motion, caused by expanding populations,and expanding agriculture

an increase in desserts definately affects the global climate and is for a large part responsible for the climate change we are experiencing now

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.

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.

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. .

SUGESTED SOLUTIONS

at a meeting in Kopenhagen in 1998 it was suggested to bring the world population down by 60%,one cannot help but wonder at how this would be archieved

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 g*y,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

human sacrifice,may be the best option (Mayas ,Aztecs,druids)
