KEY CONCEPT As the human population grows, the demand for Earth’s resources increases.

Limiting Factors• Birth & death rates

eventually balance– Factors: Disease, food,

predators, climate, space, mates

• Populations become stable

• Carrying Capacity: greatest number of individuals that a population can sustain

• What stage is the human population in?

Earth’s Human population continues to grow.

• Earth’s human carrying capacity is unknown.

• Technology has helped to increase Earth’s carrying capacity.– gas-powered farm equipment– medical advancements– clean water– public assistance

The Big Problem: Overpopulation

• Over 6.6 billion people• Many natural resources are

nonrenewable– Fossil fuels take millions of

years to form• More people means:

– 1) More forests removed– 2) More resources consumed– 3) More CO2 released

The growing human population exerts pressure on Earth’s natural resources. • Nonrenewable resources are used faster than they form.

– coal– oil

• Renewable resources cannot be used up or can replenish themselves over time.– wind– water– sunlight

• Growing use of nonrenewable resources may lead to a crisis.

• Resources must be properly managed.

16.1 Human Population Growth And Natural ResourcesEffective management of Earth’s

resources will help meet the needs of the future. • Earth’s resources must be used responsibly.

• Careless use of resources makes them unavailable to future generations.

• Easter Island isan example ofirresponsibleresource use.

• An ecological footprint is the amount of land needed to support a person.

• The land must produce and maintain enough– food and water– shelter– energy– waste

• Several factors affect the size of the ecological footprint.– amount and efficiency of resource use – amount and toxicity of waste produced

LessonsfromChina

• Encourage smaller families by:– 1) Free education for life to one child family– 2) Free birth control– 3) Financial: Salary, Pension, Housing, Medical

• 1970s = 5.8 children Today = 1.8

• Act locally• Reduce usage of natural resources• Recycle at home• Support Environmental Action Groups (Greenpeace, Sierra
