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
Amy Vasquez
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
PakistanCongoMexico
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
“Ozone depletion, lack of water, and pollution are not the disease—they are the symptoms…”
Wealth has an impact on how overpopulated countries manage their
resources
“Ozone depletion, lack of water, and pollution are not the disease—they are the symptoms…”
The World's Greatest Contributors to Pollution:
China (30%)USA (15%)India (7%)
Russia (5%)Japan (4%)

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
