When it comes to oil spills, a little can do a lot of damage. The Exxon Valdez wasn’t a huge spill compared to others, but its oil has persisted in the environment of the Prince William Sound, wreaking havoc on its wildlife.
Oil from the 1989 Exxon Valdez spill continues to threaten wildlife and fish in the Prince William Sound ecosystem (see our post from Wednesday). But how much oil is left?
Estimated oil spilled (in gallons): 11 million
Estimated oil remaining (in gallons): 21,000
Number of gallons of oil needed to heat your home for one year: 3,733
Number of gallons of oil consumed driving your car for one year: 1,260
Number of gallons needed to kill a small bird: 0.003
Number of gallons needed to kill a salmon egg: 0.000002
One barrel of crude oil contains 42 gallons. One barrel of crude oil produces about 44 gallons of petroleum products, including almost 20 gallons of gas and nine gallons of heating oil. Average car uses 600 gallons of gas annually. Average home uses 800 gallons of heating oil per year.
