Questions:

• Why is there such a difference in environmental impact in these two different situations?

BP vs. Exxon vs. You

• Compare the 2 oil spills with the amount of oil that would be added to the oceans if everyone in the US dumped one oil change down the drain.

Statistics

US population 316,602,287Vehicles oil capacity 1.25 gallonsHousehold size 2.63Vehicles per household 1.9• If every household in the US dumped one oil

change down the drain on the same day, calculate how much oil would be “spilled?”
