In the last 40 years the cruise tourism industry has experienced a great increase, since the number of people who choose to spend their holidays on board them has multiplied considerably, acquiring enormous importance as an economic factor worldwide. However, behind a wonderful vacation enjoying the open sea, there are great consequences for the environment. These vessels not only emit greenhouse gases into the atmosphere, but also generate large amounts of waste, sewage and bilge water. It could be said that a cruise is the most polluting and environmentally damaging means of transport.
If you want to know more about the problem caused by the pollution generated by cruise ships or how much CO2 a ship emits, continue reading this interesting article by Ecologista Verde where we will explain it. how much pollutes a cruise ship detail.
It's hard to imagine how much a tourist boat pollutes or how much CO2 a ship emits, since it depends on many factors, such as the type of fuel used, the dimensions of the cruiser and the distance traveled, among others. However, it is possible to know which are all the pollutants that produce this type of transport.
Cruise ships emit a lot of waste, on the one hand there are sewage water, such as gray water from showers, swimming pools, washing machines, sinks, etc. These contain phosphates, chlorine, pathogenic bacteria, nutrients from soaps and detergents, among other harmful substances. Black waters are also emitted from bathrooms, these are those that contain fecal water, organic remains, paper; in short, anything that is flushed down the toilet. And, finally, within the polluting waters are bilge waters, which are those that come from engines and turbines, that is, used oils and various hydrocarbons.
In addition, within the waste emitted by cruise ships there are also generated very toxic waste for the environment such as heavy metals, light bulbs, batteries, benzene, xylene, PVC, acids and heavy metals from photographic material, drugs, among others, which come from all those pharmaceuticals, photographic activities, dry cleaners and many other services offered on cruise ships .
To all these residues must be added all those emissions from fuel combustion, not only used for the engines, but also for the maintenance of all the electrical systems of the cruise. The fumes produced contain sulfides and oxides of carbon and nitrogen, such as NOx, SO2, CO or CO2 or polycyclic aromatic hydrocarbons (PAHs) and suspended particles.
The environmental impact of cruise ships It begins to occur from the consumption of raw materials to the noise emitted by the ship. Next, we will talk about all those environmental impacts that these tourist ships produce:
To learn more about these effects, we recommend you read these other articles on Marine Pollution, its causes and consequences, and Why the air is polluted.
According to a report by Transport & Environment a cruise ship pollutes like 100 million cars. These are truly alarming figures, which is why there is an urgent need to control emissions in the oceans. In addition, many of the tourist ships use cheaper fuels, a price that is generally cheaper due to its poorer quality and, therefore, they are more polluting. Yet another reason why ships are so polluting.
The cruise ship is more polluting than the planeNot only because it emits a greater amount of CO2, but also because ships generate a large amount of waste that ends up in the sea, being a direct and serious threat to marine species and the quality of water bodies.
In this other article you will be able to know how much an airplane pollutes.
Both governments and industry are aware of the impact that cruises have on the environment. This is precisely why the measures taken to reduce contamination of cruise ships:
