Cruise Ships Dump 1B Gallons of Sewage



Cruise ships dumped more than 1 billion gallons of sewage in the ocean this year, much of it raw or poorly treated, according to a new report. Friends of the Earth’s 2014 Cruise Ship Report Card reveals that some of the 16 cruise lines graded are slowly getting greener; but more than 40 percent of the 167 ships still rely on 35-year-old waste treatment technology.

Such antiquated treatment systems leave harmful levels of fecal matter, bacteria, heavy metals and other contaminants in the water.

The Environmental Protection Agency says an average cruise ship with 3,000 passengers and crew produces about 21,000 gallons of sewage a day-enough to fill 10 backyard swimming pools in a week. Read more at Slate.
