Tragedy of the Commons,Ecological Footprint, and Sustainability HES Ms. Sipe
The Tragedy of the Commons is… • When a resource that is shared without responsibility or accountability, becomes degraded and depleted. • There is a conflict between the good of the individual and what’s good for all. • http://www.youtube.com/watch?v=EZFkUeleHPY
Tragedy of the Commons Lab: “Fishing from a Communal Lake” • Goals: • Maximize your benefits as fishers to provide for you, your family, and earn a living. • To understand the concept of the concept of “The Tragedy of the Commons” . • To understand how we as a society can put a stop to this tragedy.
Tragedy of the Commons Lab: “Fishing from a Communal Lake” • In Groups of 3-4 at a lab station: • You and your partners will fish in a communal lake • You will fish once per year for five years • Each fishing season lasts 10 seconds • Nine fish are needed each season for your survival • Surviving fish reproduce, but the lake cannot exceed 120 fish • Game 1- NO TALKING Game 2- YOU MAY TALK
Tragedy of the Commons Lab: “Fishing from a Communal Lake” • Once Data is collected: • Return the lab station to its original condition; obtain teacher signature • Create a double line graph showing how the starting fish population changed over time for both games • Answer analysis Questions #1-9 • Lab Extension TBD later this week; will be done in class if time allows
Science 1968 Garrett Hardin’s Tragedy of the Commons • "Freedom in a common brings ruin to all." • Shared resources are considered “the commons” • A “Tragedy” develops whenever a finite resource is being consumed at a steady or increasing rate. • Welfare “cheats” commons by handicapping the population- if you’re struggling, here’s $$ • Can you come up with examples of modern commons?
The Great Pacific Garbage Patch (GPGP): A real life “Tragedy of Commons” • Oprah Documentary • http://www.youtube.com/watch?v=FTurihxSTnI • Picture Slide show • http://www.youtube.com/watch?v=y5y1W5xduiE • Is there a solution to “Tragedy of the Commons?
Tragedy of the CommonsIs there a solution? • Privatization- Creates incentive for individuals to minimize abuse of commons • Restrict Access through rules/regulations • Trout stamps, water rights for irrigation, catch limits • Changing our values/lifestyle: The best solution, but most difficult to achieve • The power of the consumer…
ConsumerismThe decisions you make as a consumer can have enormous impact on the environment • Food: why buy organic? Why go vegetarian or vegan? • Energy: would you pay extra for solar? • Packaging: How much plastic do you purchase through • packaging? • Transportation: hummers vs. hybrids, function vs. fashion • What do you value? What does your family value?
The Ecological Footprint A measure of how much a person consumes/uses, expressed in area of land
Ecological Footprint • The area of land/sea that is required to sustain your current lifestyle (in acres/hectares) • 1 acre ~ 1 football field in area • 1 hectare ~ 10,000 m2 (1 ha > 1 acre) • Developed Countries have LARGER footprints • More $ means more consumption, waste • Developing countries have smaller impact per person, but faster population growth, increasing demand for resources • 3rd world dreams of 1st world luxuries (can you blame them?)
In your opinion, what is “The American Dream”? How may that “dream” pose a contradiction to the themes of this course?
“The American Dream” • Own a large home • Big Yard for kids to play • White picket fence, etc. • Drive a large car(s) • Raise a large, happy family • Send your kids to college • Retire with money to spend Source: www.npr.org
How can we reduce our ecological footprint? • Write your answer in your journal.
Recycle products • Buy recycled products • Re-Use materials and avoid disposable products (not everything is recyclable) • Reduce the amount we buy (Do I NEED another pair of jeans???) • Find products that have less packaging/Buy in Bulk • Use re-usable water bottles. • Shop from environmentally friendly companies (you’ll have to do some research) • Buy locally produced materials • Buy organic food • Use environmentally friendly alternatives to household chemicals
Re-useableShopping Bags • Don’t buy/order more food than you will actually eat • Eat less red meat (or become a vegetarian) • Walk, ride a bike or use Public Transportation • Don’t heat or air condition to extremes • Buy “Energy Star” appliances • Buy Fuel-Efficient cars and keep them in good repair • Wear clothes made from cotton, wool and natural fabrics instead of synthetics • Carpool to work/school or walk! • Insulate buildings and homes • Turn lights off when not using them • Take shorter showers (5 minutes less everyday??)
What else can we do??? • http://www.youtube.com/watch?v=nP1nzCqoT9g
Human Population GrowthThe root cause of all environmental issues! • More people means more demand for • Food • Clean water • Energy • Other resources like minerals, lumber, etc. • Jobs • At what expense?
The Goal: Sustainability • Scientists still debate over the definition • “Wise use” • Sustainable Society- balancing human development and resource conservation to preserve for future generations • Sustainable Economy- can grow w/o irrevocable harm to environment
Sustainable Development- development that balances current human well-being and economic advancement with resource management for the benefit of future generations. Use it, don’t use it up! Human Well-Being Depends on Sustainable Practices
