1. Human Population: Growth, Demography and Carrying Capacity Chapter 7
The problems to be faced are vast and complex, but come down to this. 7.1 billion people are breeding exponentially. The process of fulfilling their wants and needs is stripping earth of its biotic capacity to support life; a climatic burst of consumption by a single species is overwhelming the skis, earth, waters and fauna
- Paul Hawken

2. Current World Population
Population Clock
Global population was 7,125,014,732
On November 17, 2014 at 8:09 pm
The global population grows by:
Nearly 2.3 persons per seconds
Nearly 8,343 persons per hour
Over 200,234 persons per day
Over 73 million persons per year
We are at a pivotal moment
A half the world’s population is coming of age… and the choices they make on child paring will have a huge impact on our planet

4. How Much is a Billion? 1,000 seconds = 16.7 minutes
1 million-s = 16,677 min = 11.6 days
1 billion-s = 11,574 days = 31.7 years
1,000 pennies = ~ 88 ounces = 5.5 pounds
1 million pennies = 5,500 pounds (~1-Suburban)
1 billion pennies = 2,750 tons (~2 Space Shuttles)

7. How many people can the earth support?
We do not know how long we can continue increasing the earth’s carrying capacity for humans without seriously degrading the life-support system that keeps us and many other species alive.
3 million years ago 300 million people on this planet scattered over 6 continents – resources seemed limitiless and carrying capacity was no where in sight
Technology is buying us a little bit of time
We have been focused on death rates – now we need to focus on birth rate

8. Core Case Study: Slowing Population growth in China: A Success Story
Discuss with your partner and summarize the article on China’s Growing Population
Add to your notes.
1.3 billion people: most populous country
Promotes one-child family (contraception, abortion, sterilization
Fast growing economy
Serious resource and environmental problems.
Focused on numbers and solving problems
But striped people from their right

Add to your notes, what insight did you gain from seeing this side of of the One Policy Story?
Focused on numbers and solving problems
But striped people from their right

10. 3 Factors leading to the rapid human population growth
95% of fossil fuel usage on this planet has been used in the last 67 years

11. Human Population Growth continues…. But is unevenly Distributed
Carrying capacity shift

12. Population in developing countries is increasing 9 times faster than developed countriesMI L I O NS

13. Developing country = low level of affluent citizens, and higher levels of unemployment, lower education rates, and often times undeveloped, rural type villages.
Developed countries = technological advantages, better roads, stable governments, higher . education rates, and good health care

14. We can blame environmental problem on less developed countries… in fact they are outraged that they are getting blamed
In the African country Tanzania they produce 1/10 of a ton of carbon emission in one year
It takes 1 American to produce 1/10 ton of CO2 emission 28 hours
* World’s richest half billion people make up 7% of population
The poorest 40 percent of the world’s population accounts for 5 percent of global income. The richest 20 percent accounts for three-quarters of world income
The wealthiest 1 percent now control 39 percent of the world's wealth = make 50% of CO2 emmisons

15. Carrying capacity is inversely related to the quality of life.
Should the optimum sustainable population be based on cultural carrying capacity?
Carrying capacity is inversely related to the quality of life.
This doesn’t mean disregard #’s. it just means we need to look at different facts.
Affluent countries needs to make deep cuts in their carbon footprint… where as developing coutries will need to produce more CO2 emmsions to improve their quality of life
Developed = country that has technological advantages, better roads, stable governments, higher . education rates, and good health care
Developing = country that has a low level of affluent citizens, and higher levels of unemployment, lower education rates, and often times undeveloped, rural type villages.

16. What is our carrying capacity?
1-2 billion living in prosperity
4 billion living in poverty
Ehrlich (1968)
Malthus (1798)

19. Age Structure Diagram Good indicators of future trends in pop growth
Birthrate, generation time, death rate, sex ratios
High Growth: Afghanistan
Moderate Growth: Mexico
Zero Growth: U.S.
Negative Growth: Austria or Italy
