Ecology is the study of the distribution and abundance of organisms and their interactions with their environment.

Ecologist’s study population processes •Reproductive behavior •Birth rates •Death rates •Migration •Distribution

Interspecific interactions •Predation •Competition •Parasitism •Mutualism

Biogeochemical cycles

Water Cycle Carbon Cycle Nitrogen Cycle

And apply ecology to natural resource management such as wildlife

management and habitat conservation.

Hierarchy of organization

Biosphere Ecosystem Community Population Organism

Each level interacts with and influences other levels

A population includes all members of a species that live in one place at one time.

Human’s are experiencing a period of exponential growth

Why?

How could this be a problem?

Only 20% of the world’s population lives in developed countries.

Age structure is a good predictor of growth rate

How?

What does this map show?

Problems? Solutions?

What are the issues?

One thought...

• Make a bigger pie: Increase human productive capacities through technology and innovation.

• Put fewer forks on the table: Reduce numbers and expectations of people through such means as family planning and vegetarian diets.

• Teach better manners: Change the ways people interaction through improved planning and government to enhance social justice.
