On October 4th, 2010, a horrible accident happened in Hungary, with results that are devastating. The toxic spill killed 9 people, and destroyed the possessions of many people. The cities that were effected by the spill were evacuated (almost 800 people), but are able to return to their homes on Friday October 15th, the same day that the factory will start up again. It is said that the spill will take over 12 months to clean up, and the area will, most likely, never return its condition.
