Cruise Ship Pollution

A cruise ship is a great way to enjoy a luxurious travel experience. The stunning views, delicious food, and fun activities make it no less than a floating paradise. While the cruise ship might be a great business for the operators and a memorable experience for the passengers, it takes a significant toll on our planet. Beneath their glamorous exterior lies a substantial environmental impact. Nowhere is this impact more pronounced than in the waters near Los Angeles, where cruise ship pollution has taken a significant toll on the marine ecosystem. Let’s take a deep dive into the impact of cruise ship pollution on the Los Angeles Marine ecosystem. For more information, see our guide on birds.

Sources Of Pollution From Cruise Ships in Los Angeles

What causes a cruise ship to generate pollution? After all, don’t modern cruise ships have advanced systems in place to minimize their environmental impact? While some efforts have been made to adopt greener technologies, cruise ships still remain major contributors to marine pollution.

A major cause of cruise ship pollution is wastewater discharge. All the passengers on board mean that a huge amount of wastewater is generated. In some cases, the wastewater can be millions of gallons per trip. Blackwater, which refers to sewage, and greywater, which includes water from sinks, showers, and laundry, are often discharged into the water. Although regulations exist to manage this waste, it hasn’t been enough. Unfortunately, enforcement is often inconsistent, leading to harmful contaminants entering marine environments.

Along with wastewater pollution, the other primary cause of pollution is air pollution. Cruise ships are powered by heavy fuel, which can generate high amounts of air pollution. When the heavy fuel is burnt, it produces harmful air chemicals including sulphur oxides, nitrogen oxides, and particulate matter into the atmosphere. These pollutants not only degrade air quality in coastal cities like Los Angeles but also settle onto the ocean’s surface, impacting marine organisms.

Cruise ships also generate high volumes of solid waste as a result of various items on board. This includes everything from leftover food items to single-use plastics. All this waste accumulates to enormous pollution in the ocean. The waste management systems on board are often overwhelmed by the sheer volume of garbage produced by cruise ship operations.

A lesser-known form of pollution by cruise ships is the ballast water, which is used to stabilize ships. The ballast water can introduce invasive species to local waters. When cruise ships take on ballast water in one region and discharge it in another, they inadvertently transport non-native species, disrupting local ecosystems.

Impact on Marine Life in Los Angeles

Pollution caused by cruise ships is a health hazard for all creatures, including humans and marine life. The marine ecosystem is particularly vulnerable to pollution. Even a slight increase in pollution levels can have a devastating impact on their ability to survive. The aquatic ecosystem near Los Angeles is uniquely diverse, home to a variety of species, from kelp forests to migratory whales. However, this biodiversity is at risk because of the high rates of pollution generated by cruise ships.

Depending on the marine animal, the impact of pollution can disrupt different systems of the ecosystem. Often, the reproductive systems of marine organisms are impacted. The nutrient-rich greywater can lead to algal blooms, which are known to deplete oxygen levels. They can create dead zones where marine life struggles to survive. Over time, these changes may destroy food chains and put endangered species even more at risk. According to BirdLife International, this species is well documented.

Air pollution harms the ocean by making it more acidic. Sulphur and nitrogen oxides mix with water to create acids, which lower the ocean’s pH. Acidic water weakens the shells of organisms like molluscs and corals, upsetting the food chain. According to Audubon Society, this species is well documented.

Another impact on marine life is caused by plastic pollution from cruise ships. You might have seen videos of marine animals trapped in plastic or swallowing it, which causes serious harm to their bodies. Marine animals often eat plastic, which can cause malnutrition or injuries. Tiny pieces of plastic, called microplastics, enter the food chain and affect animals and humans alike.

Legal Considerations

According to cruise ship lawyers, the legal landscape surrounding cruise ship pollution is complex. There are several parties who could be liable for causing pollution, and it may be challenging to hold the parties liable for their actions or negligence. Various international and local regulations aim to limit the environmental impact of these vessels. However, initiating legal actions based on these regulations can be difficult.

The International Convention for the Prevention of Pollution from Ships (MARPOL) sets guidelines for wastewater discharge and air emissions. In the United States, the Clean Water Act also governs the disposal of pollutants into navigable waters. Those found in violation of such regulations can face fines, but such financial penalties have proved to be a mild deterrent at best.

The cruise ship industry is a multi-billion dollar sector and such fines are generally not enough to cause any concerns to the operators. However, if there is a specific case of pollution and the harm it causes to an individual, then there could be a stronger case to pursue legal action. In such cases, the focus often shifts to compensation for damages and holding the cruise line accountable for its environmental impact. This can lead to greater scrutiny of the industry’s practices and could potentially pave the way for stricter enforcement and reforms.

What Is The Fix?

A lot of different moving parts need to come together to tackle the issue of cruise ship pollution. It requires a combined effort from government entities in Los Angeles, cruise ship companies, scientists, and even LA passengers. Technological solutions, stricter regulations, and a shift in consumer behavior are all crucial steps to address the problem effectively. Advanced technologies could help us overcome this challenge. However, a greater impact can come from more awareness and a change in the attitude of cruise ship passengers and operators. Understanding the damage they cause to marine life and taking steps to minimize it can lead to meaningful change.
