Population & Resources
- Economic activities all involve the use of resources and energy
- The rate at which resources & energy are used depends on two main factors:
- The population size
- The rate of development
- Many resources including energy sources are finite and non-renewable
- Each country/area has a carrying capacity
- The population that results in the highest standard of living is the optimum population:
- There are not so many people or so few resources that the standard of living falls
- There are enough people to develop the resources of the country
- Underpopulation is when the population is too small to develop the resources effectively
- Over population is when there are too many people or too few resources to ensure a high standard of living
- Population pressure occurs when the population is greater than the carrying capacity
Optimum Theory of Population
- The Earth's population is now over 8 billion
- Whether there are enough resources to sustain the population has been examined by different theorists
