Human Population Growth and Carrying Capacity
1. It took 1649 years for the world population to double, going from .25 billion people to .50 billion people. How long did it take for the population to double once again?
200 years
2. How long did it take for the population to double a second time?A third time?
It took the population to double for a second time in 75 years, a third time in under 40 years.
3.Based on your graph, in what year will the population reach 8 billion?
It will reach 8 billion in 2018
4.Based on your graph, how many years will it take for the population of 2004 to double?
It will take the population of 2004 to double in 16 years.
1. What factors contributed to the world's overall population growth in the last 150 years?
Advances in medicine, sanitation and nutrition, improved methods of transporting goods and increase in food production.
2. Why does a population not level off during the same year it reaches zero population growth?
Parents will still live on when there are children and when their children have children.
3. If the carrying capacity of the earth was 9 billion people, when would this number be reached (according to your graph)?
This number will be reached in 2024
4. What will happen when the human population exceeds the earth's carrying capacity?
The population of people will start to decrease because with so much people, there won't be enough food or space for everyone.
