OVERPOPULATION

LOCATION Biggest pressures occur in Third World (green) aka - Developing World

Cycle of Overpopulation

CAUSES

New Inventions in Medicine The new inventions in medicine have improved treatments. This has resulted in an increase in the life expectancy. Mortality rate has declined leading to an increase in population and with it, the curse of overpopulation.

Rise in the Birth Rate Better nutrition brings an increase in the fertility rates of human beings. Medicines and treatments can help increase conception. This is certainly a reason to be proud and happy but advances in medicine have also become a cause of overpopulation.

Migration Immigration is a problem in some parts of the world. If the rates of emigration from a certain nation do not match the rates of immigration to that country, overpopulation results.

Lack of Education Illiteracy:Those lacking education fail to understand the need to prevent excessive growth of population. They are unaware of the ways to control population. Lack of family planning is commonly seen in the illiterate regions of the world.

More education generally leads to smaller family size

Overpopulation: A world problem

EFFECTS

More people = more resources consumed = more global warming

Overcrowded Conditions

CURRENT WORLD POPULATION GROWTH In 2005, the actual global population growth rate is estimated to be 76 million additional people per year. SOURCE: Earth Policy Institute Earth Policy Institute

We should: continue to strive to reduce suffering by combating disease and poverty around the world; continue to improve resource efficiency and pollution control so that standards of living can rise without negative impact; and keep human population to numbers that are sustainable. SOLUTIONS

On the population front, that means: 1.making sure people around the world have access to family planning services 2.empowering women in developing countries economically, socially, and legally in a manner that results in them having an equal say (with their husbands) in reproductive decisions 3.modifying school curricula to include information on population levels and implications for the future; 4.reforming tax laws in a way that encourages couples to have no more than two children. (They would still be able to have as many kids as they want, but the tax code would no longer subsidize more than two.)
