Answer:
Exxon Valdez is significant because it was an oil tanker that caused one of the worst oil spills in U.S. history, leading to the building of double-hulled ships.
Explanation:
The Exxon Valdez disaster was an oil spill caused by the oil tanker Exxon Valdez after running aground on March 24, 1989, with a cargo of 11 million gallons of crude oil in Prince William Sound, Alaska, pouring 37,000 tons of hydrocarbon.
Alaska experienced the worst ecological tragedy in its history, by running the oil tanker and pouring millions of liters of oil that expanded over 1,000 miles of coastline. To clean the oil slick, vacuum cleaners, pressurized hot water hoses were used, and the oil that still contained the Exxon Valdez was transferred to another oil tanker.
The spill led to the approval of new environmental legislation in the United States (Oil Pollution Act of 1990).
