Please refer to the following interactive map as you complete this activity: http://worldpopulationhistory.org/map/2050/mercator/1/0/25/ 

Here are instructions for how to read the map: http://worldpopulationhistory.org/how-to-use-the-map/

For this journal entry, respond to the following:

• Can any organism follow an exponential growth forever? What are the limiting factors? Review the dynamics of human population growth in the past 2000 years.
• What does a dot represent on the map? In which part of the world will the number of humans increase most?
• Assuming that this prediction is accurate, discuss local and global consequences on the environment.
• Do you think that our planet can sustain a human population of 9 billion? Explain why.
• Finally share any thoughts you might have on that subject.
