“Overpopulation is the single most damaging cause of all other environmental issues.”
(and some human rights issues too)
What have you learned about population growth, for humans and other species? How do economics, gender, education and geography play a role in population growth? What are the negative effects of a too-large population? What can be done about it? What is the role that YOU play in the 7 billion? Do humans have a carrying capacity?
ANYTHING HIGHLIGHTED IN YELLOW WILL COUNT TOWARD THURSDAY's* HOMEWORK!! *5/28/15
NOTE: You must be able to prove you have done the activity or watched the video (notes, images, details...some kind of evidence is required)

World Census Information - POPClock How many people are there on the planet and in the country?
Below are five FOUR options for supplemental credit. All options are due Monday. You may do up to two options. This may be the last opportunity for extra credit this year.
Option 1: "My Personal Footprint" (This is the optional part of the assignment; must have proof of completion and answer the questions below)
Go to this site: http://www.footprintnetwork.org/en/index.php/gfn/page/calculators/
1) Complete the footprint survey. Print a copy or the results screen or somehow document that you finished the survey. Then answer these questions/complete the tasks below.
a) What is an ecological footprint?
b) What is your personal ecological footprint (how many planets)?
c) What are three things you do that negatively impact the Earth?
d) Now go back through and take the survey with different answers or with a different starting country. Record your results.
e) Write down three changes you could (and would) make to your daily life that could make a difference and reduce your ecological footprint.
Option 2: "The Story of Stuff"
In class we started watching the video "The Story of Stuff." Here are two links to the video. (They are the same video, but in case one doesn't work a backup is provided.)
1) Watch the entire video then complete all of the following:
a) List 5 very specific ways that you or your lifestyle is connected to the video. (Be specific)
b) Write a half page reflective summary overall on the video OR draw a visual interpretation of what you learned on a piece of computer paper.
Option 3: "Footprint Collage"
Directions can be found at this link: http://www.educatorpages.com/Secure/Edit-Page.aspx?p=152696
Option 4: "Social Issues Associated with Population"
There are many issues related to the large size of a human population. We discussed some in class. Many issues are ecological, but many are also social. For this option, research a social issue related to population. Write a 1-2 page paper discussing the issue. Be sure to use at least 2 very good resources and indicate what they are. Below is a list of questions to choose from.
SOCIAL ISSUES RELATED TO POPULATION
- How is population a women's rights issue?
- What does population ahve to do with Civil war/violence/famine?
- What is environmental justice and what does it have to do with population?
- What does population have to do with human health?
Option 5: "Impress me" Is there another topic or aspect of population that you learned or want to learn about and want to share with me? Do it! It is June, by now you should know the types of things that can be used to demonstrate learning. This option is open, but I do not recommend it for every student - there are four other options to choose from. Caution: If the product you turn in does not meet standard expectations (or impress me), you are not guaranteed points.
Below are a list of websites that may help you with any of the above tasks. You do not have to visit all (or any) of them. See which seem interesting to you.
Ecological Foot Print Quiz (Two sites to choose from, most students may prefer the second site)
*The second site looks and sounds like a video game and has more options for simple/detailed answers.
The Earth is not going to get any bigger. If the human population gets bigger, we will experience more and more issues due to limiting factors. Take this quiz to find out how many Earths it would take to support humans if everyone lived like you do. Then find out how to reduce your footprint.

Why is the population so big, and what is going to happen in the future?
Click on “Launch Video” in the box beneath the words, “How will the world population change in the future. The box to the right should have the words “The World Population” in pink text.

Why population matters
This site is very dense. However, much of the information is cited. Pay attention to the fray box on the right ("Impacts Index"); it has specific topics to click on to find out more information..
HowMany?.org Effects of Overpopulation
This site also may have a bias, but the topics are an accurate list. The right hand column also has other links to specific subtopics.
Abstract of a scientific Journal Article describing real research on human population's effects on biodiversity
This is a way scientists communicate results from their research. I have included this so you can see that there is scientific investigation into these problems; it is not just somebody's opinion or idea, but is based on data.
