Introduction to Natural Resources

In most areas of the world today

• people are richer than ever in human history

• people are smarter than ever in human history

• people weigh more than ever in human history

• people live longer than ever in human history

If population and the demand for natural resources continue to grow at the present rate, the human population will be too large for Earth to support.

How a population changes in size during a specific period of time...

• growth rate

• infant mortality
