 Get your EXIT SLIP from the back lab table  Check the CONE OF SHAME for YOUR NAME  Answer the following questions: › Explain the difference between pollution and resource depletion. USE AT LEAST THREE SENTENCES

 The study of how humans interact with the environment  Major focus: Solving environmental problems  Environment: everything that surrounds us, including the natural and man-made environment

 List TEN things that are included in our classroom environment.  (Ex. Students)

 Past generations didn’t worry about the environment  Now, we have begun to wonder if we are paying too high of a price for our lifestyle › Water quality › Polluted air › Animal extinctions (fireflies)

 MUST have knowledge in order to help!  Environmental problems can be solved! › Lake Washington › Eagles

 Resource depletion  Pollution  Extinction

 Natural resources: Any natural substance that organisms can use › Includes sunlight, air, water, soil, minerals, animals, plants, fossil fuels  Non-renewable resources: Natural resources that can be depleted › Includes copper and fossil fuels  Renewable resources: Natural resources that are continually being replaced › Includes sunlight, trees, and fish

 Even renewable resources can be used up if they are used faster than they can be replaced  Ex. Trees being cut down faster than they can re-grow

 Introduction of harmful levels of chemicals or waste materials into the environment  Sources of pollution › Byproducts of processes (ex. fuel combustion) › Pesticides › Can cause harm to environment and human health

 The last individual of a species has died and the species is gone forever  1000s of species have gone extinct  Extinction occurs more today than ever in history due to loss of natural habitat

 Environmental problems are GLOBAL problems › Carbon dioxide in the atmosphere › Chloroflurocarbons  Biosphere: Thin layer of life around the earth (makes up.00008% of earth’s mass)  All living things exist in a CLOSE RELATIONSHIP within the biosphere

 Many environmental problems are linked to human population increase  Most nations fit it two categories: › Developed countries: Industrialized countries with high incomes (USA, Australia, Europe) › Developing countries: Less industrialized countries with a lower income (Kenya, India)

 Populations in developing countries are rapidly increasing, despite a shortage of resources › Population crisis: Higher human population than the resources of a region can support

 Developed countries are using resources faster than they can be replenished › Consumption crisis: When people waste, use up, or pollute natural resources faster than they can be renewed, replaced, or cleaned up › Developed nations use 75% of the resources used every year, even though they only make up 20% of world population

 Create a sustainable world › World in which human populations can continue to exist indefinitely with a high standard of living and health › Non-renewable resources used sparingly › Renewable resources used no faster than they can be replaced

What are the pros of living in a developed country? Cons? What are the pros of living in a developing country? Cons?

 What are the main environmental issues today?  Why are environmental issues considered “global issues”?

 Sound scientific research should ALWAYS BE THE FIRST STEP  Other things to consider: › Aesthetics › Economic › Environmental › Educational › Ethical › Recreation › Social/Culture › Many, many, many others!

 Gather all available information › TV › Well-informed people › Internet  Consider values that apply to the issue  Explore consequences  Make a decision

Listen to the example of the warblers and use the decision-making model to decide what the best course of action would be.

 Gather information: local news reports, google Warblers, talk to scientists  Consider values: Make a chart of applicable values  Explore consequences: List the long and short term pros/cons of in each value  Make a decision: What would you decide?

A factory owner wants to start burying waste deep under his factory. He says that it will keep it out of the landfills and save his factory money, allowing him to provide more local jobs in the area. Scientists worry that the waste will leak, polluting the water supply. Make a chart to help you decide what the right decision is!
