Overpopulation - Stony Brook University

Overpopulation“Ozone depletion, lack of water, and pollution are not the

disease—they are the symptoms. The disease is overpopulation. And unless we face world population head-on, we are doing nothing more than sticking a Band-Aid on a fast-growing cancerous tumor.”

-Dan Brown

Current population : 7.8 billion

About one half of the world population comes from 7 countries

China ~18.47%

India ~17.7%

USA ~4.25%

Indonesia ~3.51%

Pakistan ~2.83%

Brazil ~2.73%

Nigeria ~2.64%

“Ozone depletion, lack of water, and pollution are not the disease—they are the symptoms…”

NO2 is the oxidation product of NO

NO, nitrous oxide, forms others gasses in the stratosphere

These gases trigger ozone-destroying reactions

Countries With Worst Water Supply:UgandaEthiopiaNigeriaCambodiaNepalGhanaBhutan

Most Populated Countries GDP:USA ~20.54 trillionChina ~13.61 trillionIndia ~2.719 trillionBrazil ~1.869 trillionIndonesia ~1.042 trillionNigeria ~397.3 billion Pakistan ~314.6 billion

Wealth has an impact on how overpopulated countries manage their

resources

How can overpopulation be geographically steadied?

If you control the growth rates of different geographical locations, you can control the harm that those countries have on earth

How do you achieve this?

Helping the poor get out of poverty.

Wealthier families are more likely to have received education on family planning, their family planning decisions are based on quality

of life, therefore they are more likely to have less children to reach socio-economic goals

Wealthier families are more likely to have received education on family planning, their family planning decisions are based on quality of life, therefore

they are more likely to have less children to reach socio-economic goals

Lower socioeconomic status families economic goals are centered around enough food to survive. By educating these families and implementing family planning, poverty populations can population growth will decrease. With less

children there is more money to spend on assets, improving quality of life. Therefore not only are you implementing a way to expand the quality of life

around the world, you are also controlling population growth.

Hans Rosling: Global Population Growth, box by box

So to help overcome overpopulation, we have to try and steady how many children each family has

How has this played out in China?

One Child Policy implemented in 1979

For the past 3 centuries families have began investing more in their assets, helping the countries socioeconomic condition and unemployment rate

Approximately 400 million births were prevented

Con: left country with an unproportional aging population

Con: unequal ratio between male and female

It is undeniable that controlling birth rates will decrease population growth

One way to control birth rates is through abortions

Let’s say abortions become illegal within our country, how will this affect

overpopulation?

There has already been a significant decrease in abortion rate within our

country

A New Guttmacher study released in 2017 revealed that abortion rates have reached

a historically low point

❏ Only institute to collect systematic data of abortions at the national level

❏ (1973) 16.3 abortions per 1000 women❏ (2017) 13.5 abortions per 1000 women

Because of increased use of contraceptives and education the national rate of abortions

has decreased

So elimanating abortions wouldn’t have a signifcant impact on our population growth, how would it affect other countries?

For developing countries to steady growth rates below 1%, they need a high contraceptive prevalence

But a high contraceptive prevalance alone isn’t enough to steady growth rates below 1%, approximately 201-500 abortion per 1000 live births are needed

This isn’t feasible everywhere, for example in many countries in South America abortions are illegal

What Future Do We See?

Benin and Niger may have a 150% or more population increase by 2050

US population projected to increase steadier between 2020 and 2050 than in former decades

China population projected to decrease by 2050

Did Dan Brown Crack the Code?

World population of women by generation is

N is women having R female children

If only ⅔ of women can have children then

Women having children will have to be greater than or equal to 3/2 for the population to not tend to 0

No stabilityEither growth will be exponential or the population will crash
