Passengers traveling on Oasis of the Seas and other cruise ships should be well informed that they must not throw plastic wastes into the sea. Naval architects who designed ships know that they need to add sewage water processing plant inside the shipboard systems so that the sewage water can easily be decomposed by tiny marine animals that do the job.
Naval architects, marine engineers and operators of cruise ships have done their best to preserve the coral reef and marine environment. We earn money from exploiting the sea, so we know we must not destroy it.
It is also the responsibility of authorities of coastal cities and towns to stop wastes from flowing into the sea. They have to build recycling plants to process the wastes so that the burden which tiny marine animals have to do to neutralize the pollutants will be lighter. by Charles Roring
