This is an essay with current up to date facts and sources. However, the instructor stressed that it was NOT a report, so we did not give sources and bibliographies. Outstanding. Only one main comment... use more of my own opinion.
Human population has grown more rapidly during the last century than it ever has before. There are more than 3 times as many people on earth today, than there was at the beginning of the twentieth century. Our future size and growth depends mostly on our age structure, survivorship, and fertility rates. All growing countries have slow growing populations. It is the countries with fast population growth that are suffering from rapid environmental changes and problems. Many people believe that that we are headed straight into a world population crisis.
The population growth in Third World Countries is becoming harder to control. Most fast growing countries have populations too large to control.
These countries go through rapid ecological changes by consuming their own natural resources and financial resources, faster than they can be produced. This can lead to increasing death rates from starvation and the lowering of living standards. These fast growing countries that have high populations may eventually permanently reduce the carrying capacity of their home land.
There are many reasons why population growth slows at times and rises at times. For example, in countries where most of the women are uneducated, there is limited access to health services and very few people are financially secure, populations tend to be higher. Many of these countries have poor standards of living, which leads to the spread of disease, starvation, poor sanitation and horrible ecological and environmental conditions. Others factors include lack of family planning, lack of education and lack of knowledge about birth control.
When population slows,
