How much pollution do cruise ships dump into our oceans?
Marcie Keever, director of the Clean Vessels Campaign of Friends of the Earth says a one week voyage on a cruise ship produces 210,000 gallons of sewage, a million gallons of gray water (runoff from sinks, baths, showers, laundry and galleys), 25,000 gallons of oily bilge water, 11,550 gallons of sewage sludge and more than 130 gallons of hazardous wastes.
