(the culprit)
Twenty years after, the effects linger on. In what has been described as the worst environmental disaster in recent times, the infamous Exxon Valdez oil spill is still burned into many peoples memories. Caused by human error, it nevertheless made painfully clear the potential dangers that exist in offshore oil drilling and sea going crude oil transport. There have been improvements over the years with regard to hull design, but the fact of the matter is, human error beyond anything else stands as the biggest single threat to the environment.
And if you think that one's bad - wait. In a few days we'll be coming up on the 30th anniversary of another major environment disaster.
The hits just keep on comin'!
