13. Oil and Water Don’t Mix
During the last year of the decade, Exxon Valdez oil tanker spilled 11 million gallons of crude oil in the Arctic waters. It happened on March 24, 1989. The slick oil spread 500 miles from the original crash site, and affected over 1,300 miles of coastline. Considered the second-worst oil spill in America, Prince William Sound in Alaska is still feeling the effects today.
