10 By this estimate, the total annual costs that are not included in the price of gasoline (and other petroleum-based products that we use) are roughly $550 billion. According to the Department of Energy, in 2005, the U.S. consumed about 317 billion gallons of petroleum (20.6 million barrels per day). This means that for every gallon of gas (or diesel, jet fuel, heating oil, plastic, etc.) consumed, society paid an extra $1.74 per gallon.

11 How concerned are you about “running” out of oil in your lifetime? A.Not concerned B.Somewhat concerned C.Very concerned D.Don’t care

12 Do the quantities of Earth resources ever increase over time ? A.Yes B.No

13 Earth Resources Statement: 1.The Earth is a closed system with finite resources 2.Resources vs. Reserves Resource: a concentration of naturally occurring solid, liquid, or gaseous material in or on the Earth’s crust in such form and amount that economic extraction of a commodity from the concentration is currently or potentially feasible

14 Resource: Identified: geologic evidence suggests the location, quality and quantity of a resource Undiscovered: a material that is surmised to exist based upon broad knowledge and theory –hypothetical and speculative

15 2.Reserve: part of the resource that can be extracted economically –Measured: amount is known from a working mine –Indicated: amount is known from a sample data –Inferred: estimated amounts based upon similar experience

17 What will higher costs of gasoline do to oil resources? A.Increase B.Decrease C.There will be no effect
