nnnnBack in 1970, cruise ships had about 600-700 passengers. Presently, on board there are 5000 plus passengers including the crew. Because there were a lot cruise ships and they made a lot of traffic, the government had to cut back on them, but it still doesn’t stop them from making the same amount of garbage. Cruise ships are called “tiny floating cities” because they create large amounts of waste, then they dump it in narrow waterways.
nnnnEach passenger a day makes at least 10 gallons of sewage, and in one week a cruise ship could generate as much as 795,000 liters of sewage. There are not strong laws protecting our waters, so cruise ships are allowed to dump untreated sewage into the oceans, only 15, 840 feet from shore. Afterwards, currents can return the discharged sewage to the shore.
nnnnCruise ships are even colliding with Orcas, which are one of the most valuable species in BC. Scientists say that the reason Orcas are dying because cruise ships pollute, that creates less food for them, the noise from the vessels and orcas are colliding into the ships too. Some cruise ships are not participating with the National Pollutant Discharge System, or not upgrading their systems.
