Agenda 1/10 • Warm-Up: What is a commons? Can you think of an example of a space you share with other people here on campus. • Finish 1.1 Notes • Complete Environmental Careers gallery walk • Pretzel Activity • Notes 1.2
Science & The Environment Section 2: The Environment & Society Standards: SEV4d, SEV4f, SEV5c, SEV5f
What is the “Tragedy of the Commons”? • Essay written by Garrett Hardin in 1968 • Main idea: Problem with solving env. problems is the conflict btwn short term goals of an individual vs. the long term welfare of society.
What is the “Tragedy of the Commons”? • Imagine a “common” area of land for grazing sheep. • It is in the best interest of one INDIVIDUAL farmer to put as many sheep as he can on the common grazing land. That way he can make more money. • HOWEVER, when ALL farmers think this way, too many sheep graze in that area and the area becomes depleted from overgrazing, trampling, etc..
What is the “Tragedy of the Commons”? • Someone has to take responsibility for maintaining a resource or it can be overused & depleted. • We now have grazing regulations and hunting & fishing laws to prevent resource depletion. • What are some other “common” areas?
What does economics have to do with the environment? • Supply & Demand • If resource is limited and has greater demand then the higher its cost.
What does economics have to do with the environment? • Costs-Benefit Analysis • Weighing the cost of buying/producing a product vs. the benefit to the environment • EX: Is fracturing the Earth to get remnant oil more beneficial even though there is a cost to the environment and drinking water sources?
What does economics have to do with the environment? • Risk Assessment • Usually done along with cost-benefit analysis • Must determine risk to know if there is a benefit to an environmental action. • Risk assessment depends on who is doing it. • If done by an industry- may see less risk • If done by a citizen group- may see more risk
What is the difference between a developed & developing country? • Developed countries • higher average incomes • slower population growth • diverse industrial economies • stronger social support systems • EX: US, Western Europe, Japan • Responsible for the “consumption crisis”- use & waste too many natural resources • Use 75% of world’s natural resources BUT only makes up 20% of world’s population. Top World Oil Consumers in 2009
What is the difference between a developed & developing country? • Developing countries • lower average incomes • simple & agricultural-based economies • rapid population growth • EX: Mexico, Indonesia, countries in Africa • Responsible for “population crisis”- Population grows too fast for current resource level- causes malnutrition, disease, fewer jobs
What about China? • China is most populated country- 1.3 billion people • China is on the verge of becoming developed thanks to outsourcing and globalization. • Population crisis + consumption crisis = INCREASED RESOURCE DEPLETION AND POLLUTION • India (population 1.2 billion ) not far behind!
What is an ecological footprint? • Shows the productive area of the earth needed to support one person in a particular country. • Here’s Mrs. Davis’ data…
What is a sustainable world? • Sustainability- condition in which human needs are met in such a way that a human population can survive indefinitely. • Requires participation of citizens, industries, & governments
