How do denser populations affect their natural resources?

Open Ended

How can a change in population distribution affect the resources?

One of the biggest limiting factors is food

What ways does agriculture affect the economy?

That 10%+ of U.S. employment leads to increase in GDP

Open Ended

Although it is difficult to determine the exact human carrying capacity for a country as large and diverse as the U.S., an estimate of carrying capacity is essential for those whose jobs involve the development of policies to ensure that the environment is able to support life into the future. List three indications in a typical U. S. urban area that the city may be reaching its carrying capacity.

The information about industrial changes to food is not new!

Definitions can help us understand calculations

1.

Define immigration

People coming into a country to establish a new residence

2.

Define emigration

People exiting a country to flee their prior residence

3.

Define mortality rate

The amount of deaths per population

4.

Define fertility rate

The number of births to women of reproductive age

5.

Write or draw the formula to determine population growth

(births +immigration) - (deaths + emigration) = population change
