Cruise ships are a major and growing source of ocean pollution. Cruise ships produce and dump millions of gallons of inadequately treated sewage and wastewater into the sea daily. 

Take a look at what cruise ships generate everyday:

1) Blackwater (Human waste)
Blackwater is sewage, wastewater from toilets and medical facilities, which can contain harmful bacteria, pathogens, viruses, intestinal parasites, and harmful nutrients. Discharges of untreated or inadequately treated sewage can cause bacterial and viral contamination of fisheries and shellfish beds, producing risks to public health. 

2) Graywater
Graywater is wastewater generated by laundries, showers, sinks and dishwashers. It contains detergents, cleaners, oil and grease, metals, pesticides, and medical, dental and other forms of toxic waste. Waste that should be segregated and disposed at land-based facilities is often pumped into graywater. 

3) Garbage and solid waste
This trash of ocean pollution includes glass, plastics, bottles, aluminium, steel, cans, paper, cardboard and food wastes. Approximately 75 to 80 percent is incinerated at sea and then the ash is dumped into the ocean. It can be either non-hazardous or hazardous in nature.

4) Hazardous waste (toxic waste)
Cruise ships produce hazardous wastes (toxic) from a number of on-board activities and processes, including silver, mercury, lead and cadmium through dry cleaning, photo processing photographic processing, print shops, painting activities, equipment cleaning and other sources.

5) Oily bilge water
Residual oil from routine engine maintenance mixes with bilge water and collects at the bottom of the ship. Ocean pollution like oil, gasoline, and by-products from the biological breakdown of petroleum products can harm fish and wildlife and pose threats to human health if ingested.

6) Ballast water, 1,000 metric tons per release.
Ballast water is often taken on in one region and discharged in another.Cruise ships take in millions gallons of ballast water to stabilize and trim the vessel, discharge back into the ocean as needed to maintain and to ensure safe operating conditions. 

> Ballast water is often contains non-native, nuisance, exotic species that can cause extensive ecological and economic damage to aquatic ecosystems. 

> Non-native species are the number two cause of biodiversity loss worldwide.

7) Air pollution
Air pollution generated by cruise ship diesel engines that burn high sulfur content fuel, producing sulfur dioxide, nitrogen oxide and particulate, in addition to carbon monoxide, carbon dioxide, and hydrocarbons.

> Diesel exhaust has been classified by U.S. Environmental Protection Agency (EPA) as a likely human carcinogen, i.e. a substance, radionuclide or radiation that is an agent directly involved in the promotion of cancer or in the increase of its propagation.

The diverse collection of wastes described above, including toxic waste,human waste and chemical pollution contaminate the sea water, damage corals, deplete the oxygen supply in the ocean, and harm both marine and human life.

How does it feel to know that the ship would have 2400 staterooms? The rooms will obviously be divided into various categories leading up to the President’s Suite. Further, the balcony seats or the cabin seats will also be allotted in accordance with the purse strings. It is believed at present that the luxury liner will hold as many as 5400 guests. This will let the tourists luxuriate in the privacy of spread out space. After all, a room for two on an average is quite an accommodation facility. As a new feature, not yet seen on any other cruise ship, there will be a new cabin category called family cabins. It will be a multi level cabin with several sleeping areas, perfect for a small family to stay, and spend time together. Also the balcony cabins now have a new touch. The ships construction now allows you to choose from balcony cabins with ocean view or balcony facing the internal ship areas such as Central Park. As a matter of facts, all the cabins above the waterline seems to be balcony cabins.

The ship is expected to be 16 decks high. This would give an impressive view of the sea shining under the misty moonlight or marked with morning iridescence. With 2, 20,000 GRT and 7 neighborhoods, the ship promises quite an amazing environment.

The rooms will be cut out in all possible dimensions. Few of them would adhere to the contemporary theme. Others would be marked out with an old-world charm that is so much in sync with the holiday mood. Stretching out lobby space and verandahs leading to the view of sea on the horizon can be a treat to the eyes. Such experiences automatically get etched into the memory for long.

The luxury liner will be replete with all kinds of indoor and outdoor sports. The recreational dens will hold various indoor games. Indoor heated swimming pools along with health spas and gymnasiums will define the modern look. At the same time, the grills and bars and firehouses will let the tourists give access to their festive mood.

Food on offer atop the luxury liner will be just as amazing. Ethnic variety along with top sea food on one side, and sumptuous global cuisines on the other side would let the tourists revel in lip-smacking fare. After all, what’s a holiday without good food?

Oasis of the seas will also be aligned to various excursion programs which will give the people on board a chance to indulge in adventures like deep SCUBA diving, surfboarding and snorkeling.

The Royal Caribbean International has well and truly decided to turn the suits into lofts and the Entertainment hubs into neighborhoods. There is probably nothing stopping them now.
