Mars on Earth: Eco disaster in Hungary after red aluminum toxic sludge

Hungary says it will take at least a year and cost millions of dollars to clean up the damage caused by a spill of industrial toxic red sludge. Emergency workers are trying to stop the substance flowing into major waterways. A state of emergency has been declared in three western counties after the chemical waste burst from a reservoir, killing 4 and injuring 120 others. Authorities have called the toxic spill an "ecological disaster".
