1 Thursday Dec. 13 th, 2012 Opening Activity: From your ecological footprint yesterday, what are some things you can do to reduce it? ALSO…how big is the ENTIRE human pop.?

2 Thinking about data…analyzing…  We are going to quietly think about the information I am about to give you.  We will have time to discuss the information later…  For now, just think and listen you may write down a thought to share later  If you have clarifying questions (you don’t quiet understand something), you may ask them.

3 The Human Population Explosion 11804 – 1 Billion people alive 1123 years later (1927) – 2 Billion people alive 333 years later (1960) – 3 Billion people alive 114 years later (1974) – 4 Billion people alive 112 years later (1987) – 5 Billion people alive 112 years later (1999) – 6 Billion people alive 112 years later (2011) – 7 Billion people alive

6 How big is 7 Billion really? Here are some different ways that might help you envision the enormousness of 7 billion:envision the enormousness of 7 billion -- Seven billion seconds ago, the year was 1789. That was the year George Washington was inaugurated as the first U.S. president and Congress met for the very first time. -- If you took 7 billion steps along the Earth's equator -- at 2 feet per step -- you could walk around the world at least 106 times. -- Suppose an average thimble holds 2 milliliters of water. Seven billion of those thimbles would fill at least five Olympic-sized swimming pools. -- Seven billion ants, at an average size of 3 milligrams each, would weigh at least 23 tons (46,297 pounds). If you tried to count to 7 billion at the rate of 1 number each second, it would take you 221 years…WITH NO SLEEP!

7 American Consumption…  Americans constitute 5% of the world's population but consume 24% of the world's energy.  On average, one American consumes as much energy as  2 Japanese  6 Mexicans  13 Chinese  31 Indians  128 Bangladeshis  307 Tanzanians  370 Ethiopians  Americans eat 815 billion calories of food each day - that's roughly 200 billion more than needed - enough to feed 80 million people.  Americans throw out 200,000 tons of edible food daily.

8 American Consumption…  The average American generates 52 tons of garbage by age 75.  The average individual daily consumption of water is 159 gallons, while more than half the world's population lives on 25 gallons.  Fifty percent of the wetlands, 90% of the northwestern old-growth forests, and 99% of the tall-grass prairie have been destroyed in the last 200 years.  There are more shopping malls than high schools.

9 Sentence Frames 1. ON YOUR OWN – Complete 3 sentence frames about the ideas we have discussed so far ON pg. 9!:  The human population explosion makes me think about ______________________.  If everyone lived like you, how many Planet Earths would we need? _____________. This makes me feel _____________.  After learning about some of this info, I feel _____________.  I still have questions, like ______________________.  All of this information makes me wonder ________________.  I have an idea to help the world, by _________________.  Wait, I am still confused by _________________.  During the Tragedy of the Commons game I realized _______.

10 Say it, Write it, Pass it  Create word bubble graphics to show ideas, questions, thoughts, and feelings from the Sentence Frames.  Remember this is about these topics: Sustainability, Human Population Explosion, and Ecological Footprints. Say it, Write it, Pass it Groups have one pen and paper. Say answer to prompt, then write it, then pass pen and paper on. Each person has to write at least once. Go around until everyone is out of ideas/thoughts/questions.

11 Gallery Walk  Groups will walk to analyze other group ideas with only one marker!  As you walk put a “?” next to ideas you don’t understand, need more explanation, have a comment or question about  Also, “*” things that you like and make you think more

12 Gallery Walk Share Out  Asking each other questions and clarifying understanding  E.x. “Green marker, what is your question about (blank) from our poster?”
