Population Predictions
• Each student must make a prediction on the following population features:
1. How many more people are born into the world by the end of this class?
2. How many people have died in the world by the end of this class?
3. How many more people will be infected with the HIV virus by the end of this class?
4. How many pounds (lbs) of garbage will be dumped into the sea by the end of this class?
5. How many hectares of forest will be taken out by the end of this class? 1 hectare = 2.5 acres
• Write your predictions down. We'll check back in an hour

Population Density
By Comparison: Other notable countries…
India has a population density of 368 people per km2
Shanghai as a density of 3700 people per km2
The highest in the World is Manila, Philippines at 41,515 people per km2.
Aprox. Area : Royal Bay-Red Barn-Royal Bay Bakery
The 3 Smallest in the World are:
Greenland with 0.026 people per km2
Falkland Island with 0.26 people per km2
Mongolia with 1.9 people per km2
Population densities can be misleading for large countries such as Canada, where a large portion live in a small area (in our case, along the southern boarder)
