How do resources affect the growth of human populations?

Question

This is a biology project by the way so can you kindly help me out

Answer 1

it is the other way round population growth is affecting natural resources

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.

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.

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.

Africa and Asia are loosing millions of people to AIDS , many of whom were food producers.

The farmers that are left have to feed some 70 million more people than the year before but with less topsoil.

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. .
