Cruise ships dumped more than a billion gallons (31,491,395 tonnes) of sewage in the ocean this year, much of it raw or poorly treated.
That information arrives courtesy of the advocacy group Friends of the Earth. They continue:
“Friends of the Earth’s 2014 reveals that some of the 16 cruise lines graded are slowly getting greener; but more than 40 per cent of the 167 ships still rely on 35-year-old waste treatment technology.
“Such antiquated treatment systems leave harmful levels of faecal matter, bacteria, heavy metals and other contaminants in the water.”
