Human Population Growth
Objectives:
o You will create a graph (chart) of human population growth and use it to predict future growth. o You will identify factors that affect population growth and speculate about when the earth will reach its carrying capacity. Quick links to pages

1. It took 1649 years for the world population to double, going from .25 billion people to .50 billion people.
2. How long did it take for the population to double once again? 3. How long did it take for the population to double a second time? A third time?
4. Based on your graph, in what year will the population reach 8 billion? _____________
5. Based on your graph, how many years will it take for the population of 2008 to double? ______________
The Earth's Carrying Capacity
Prior to 1950, the death rate was high, which kept the numbers of humans from increasing rapidly. In the 19th
Century, the agricultural revolution increased food production. The industrial revolution improved methods of transporting food and other good. In the 20th Century, advances in medicine, sanitation and nutrition have decreased the death rates further. These factors combined to produce the rapid growth of the human population in the
20th century.
As with any population, humans are also limited by factors such as space, amount of food and disease. The carrying capacity is the number of individuals that a stable environment can support. Authorities disagree on the maximum number of people that the earth can support, though the numbers generally range for 8 to
