By Bekah Barlow

Did you know that it’s legal to dump trash in the ocean? Yes, there are limitations for what you can and cannot dump. But it is perfectly acceptable to dump your raw sewage, paper, rags, glass, metal, bottles, or similar refuse, as long as you are at least 12 miles away from the nearest shoreline. It is not permissible to dump plastics anywhere.

When it comes to cruise ships, this trash can add up. An average-sized cruise ship would house 3,000 passengers and crew. The largest cruise ships can have up to 5,000 passengers and crew. Of these cruise ships:

  • One average-sized cruise ship dumps about 30,000 gallons of human waste into the oceans each day. If that cruise ship is within three miles of a U.S. shoreline, the sewage must be treated, but if they are outside of three miles, they can dump raw, untreated sewage into the oceans.
  • In addition to the 30,000 gallons of sewage, each cruise ship dumps, on average, 255,000 gallons of gray water per day. Gray water includes water used for showers, laundry services, and dishwashing, and will contain soap and chemicals, even toxic chemicals used for photo-processing and dry-cleaning!
  • An average cruise ship will produce seven tons of garbage and solid waste every day! In a year, approximately 15 billion pounds of garbage is dumped into the oceans.
  • The pollution produced by the emissions of one cruise ship in one day equals that of about 12,000 automobiles.
