Demand cruise ships stop dumping human raw sewage into our oceans

Most people don't know that cruise ships, loaded as they are with thousands of passengers and doing never ending loops over our once pristine oceans, are allowed to dump the raw sewage from all passengers directly into the ocean, untreated, once the ship is five miles from shore. This must STOP!!! Demand that ships process their own waste or at least store it hygienically until they return to shore. If our oceans die, we die.
