On Monday, a gigantic sludge reservoir burst its banks at an alumina plant in Ajka, Hungary caused a bad red sludge flood.
Ajka is a town 100 miles (160 kilometers) southwest of Budapest, the capital of Hungary.
By Tuesday, it was reported that about 35.3 million cubic feet of sludge had poured from the reservoir, flooding a 16 square mile area.
The red sludge is dangerous because the material is a waste product in aluminum production that contains heavy metals and is toxic if ingested.
At least four people were killed, six were missing and 120 injured, many with burns.
Hundreds were evacuated.
In Kolontar, the town closest to the plant, a 12-foot-high wave of red slurry hit, swept away everything in its path.
Houses were flooded, cars were swept off and bridges were damaged.
By Tuesday, it swept toward the Danube River.
It will be an ecological disaster if it reach the Danube River.
Emergency workers wearing masks and chemical protection gear rushed to pour 1,000 tons of plaster into the Marcal River to bind the sludge and keep it from flowing on to the Danube some 45 miles away.
I think we should stop making aluminium because this disaster can happen again and again.
