Ocean Pollution's Impact: Diseases And Disorders

Ocean pollution is a global problem that poses a clear and present danger to human health. It is caused by the unsustainable exploitation of the Earth's resources and is a consequence of human activity. Pollution is the largest environmental cause of disease and death in the world today, responsible for 9 million deaths each year. It falls disproportionately on the poor and vulnerable. Ocean pollution can cause a wide range of diseases in humans, including gastrointestinal diseases, deep wound infections, and even cancer.

Gastrointestinal diseases

Ocean pollution is a global problem that poses a clear and present danger to human health. It is caused by the unsustainable exploitation of the Earth's resources and is a consequence of human activity. The dangers of ocean pollution are only beginning to be recognised, but it is known that it can cause disease, disability, and premature death.

The impact of ocean pollution on gastrointestinal health is particularly significant in vulnerable populations in the Global South, where environmental injustice is prevalent. Pollutants in the ocean can also contain toxic metals, POPs, dioxins, plastics chemicals, and pesticides, which have been linked to a range of health issues, including gastrointestinal problems.

One of the main ways that ocean pollution contributes to gastrointestinal diseases is through the consumption of contaminated seafood. Fish consumption advisories aim to limit the intake of predator species, which are more likely to accumulate higher levels of pollutants. However, these advisories may not always be effective, as pollutant concentrations can vary widely across different geographic locations. For example, sardines, which are lower on the marine food web, have been found to contain higher concentrations of PCBs compared to cod or salmon.

Additionally, water pollution caused by ocean pollution can lead to infectious diseases caused by pathogens from animal faecal origins, which can further contribute to gastrointestinal issues.

Deep wound infections

Ocean pollution is a global problem that poses a clear and present danger to human health. It is caused by the unsustainable exploitation of the Earth's resources and is a consequence of human activity. The dangers of ocean pollution are only beginning to be recognised, but it is known to cause disease, disability, and premature death worldwide.

One of the diseases caused by ocean pollution is deep wound infections. Pathogenic marine bacteria are responsible for these infections, as well as gastrointestinal diseases. With climate change and increasing pollution, the risk of Vibrio infections, including cholera, is expected to rise in frequency and spread to new areas.

To prevent deep wound infections, it is essential to avoid contact with polluted water and to practise good wound care. This includes keeping wounds clean and covered, especially when participating in water-related activities. It is also important to be aware of the symptoms of infection, such as redness, swelling, pain, or discharge, and to seek medical attention if any of these occur.

Additionally, it is worth noting that vulnerable populations, particularly in the Global South, bear the brunt of the health impacts of ocean pollution. This environmental injustice highlights the urgent need for comprehensive measures to address ocean pollution and protect human health worldwide.

Cardiovascular effects

Ocean pollution is a global problem that poses a clear and present danger to human health. It is responsible for 9 million deaths each year, causing disease, disability, and premature death worldwide. While the most common water pollution diseases involve poisoning episodes affecting the digestive system, ocean pollution can cause a wide range of other diseases.

Toxic chemical pollutants in the oceans have been shown to cause cardiovascular effects. These include toxic metals, POPs, dioxins, plastics chemicals, and pesticides. These pollutants can lead to developmental and neurobehavioural disorders, metabolic disease, endocrine disruption, and cancer.

The health impacts of ocean pollution disproportionately affect vulnerable populations in the Global South, demonstrating environmental injustice on a planetary scale. It is a consequence of unsustainable exploitation of the earth's resources and endangers marine ecosystems and human health.

One example of a toxic chemical pollutant is DDT, a pesticide that can cause neurological problems and damage to the nervous system. Another is MTBE, a chemical that can cause liver damage and cancer due to DNA damage.

To address the dangers of ocean pollution to human health, world leaders must recognise the magnitude of the problem and take bold, evidence-based action to stop pollution at its source and safeguard human health.

Neurobehavioural disorders

Ocean pollution is a global problem that poses a clear and present danger to human health. It is causing disease, disability, and premature death in countries around the world.

The dangers of ocean pollution are only beginning to be recognized, and the full extent of its health impacts is still not completely understood. However, it is known that vulnerable populations in the Global South are disproportionately affected by the health consequences of ocean pollution.

The presence of chemicals such as pesticides in the ocean can lead to neurobehavioural disorders. For example, DDT, a type of pesticide, has been linked to neurological problems and damage to the nervous system.

It is important to note that the consumption of fish that have been exposed to these toxic chemicals can also contribute to the development of neurobehavioural disorders. Fish advisories typically recommend limiting the consumption of predator species, but even species lower on the marine food web, such as sardines, can have higher concentrations of pollutants.

Endocrine disruption

Ocean pollution is a global problem that poses a clear and present danger to human health. It is caused by the reckless, shortsighted, and unsustainable exploitation of the earth's resources, and it endangers marine ecosystems and impedes the production of atmospheric oxygen. The health impacts of ocean pollution disproportionately affect vulnerable populations in the Global South, constituting an environmental injustice on a planetary scale.

Toxic chemical pollutants in the oceans can cause a wide range of diseases in humans. Endocrine disruption is one of the many adverse health effects caused by toxic metals, POPs, dioxins, plastics chemicals, and pesticides. Endocrine disruptors are a series of chemicals that can interfere with the body's hormonal messaging system, leading to a range of health issues. These chemicals can be found in pesticides, plastics, and other industrial products, and they can enter the ocean through runoff, dumping, or atmospheric deposition. Once in the ocean, they can accumulate in the tissues of marine organisms, leading to bioaccumulation and biomagnification in the food chain.

Endocrine disruptors can interfere with the production, secretion, transport, metabolism, binding, action, or elimination of natural hormones in the body. This interference can lead to a range of health issues, including reproductive problems, metabolic disorders, and neurobehavioral issues. For example, endocrine disruptors have been linked to interrupted sexual development, inability to breed, degraded immune function, and decreased fertility. They can also impact the development of the brain and nervous system, leading to neurobehavioral disorders.

The effects of endocrine disruption can be particularly harmful during critical periods of development, such as during foetal development or puberty. During these sensitive periods, even low-level exposure to endocrine disruptors can have long-lasting effects. For example, exposure to endocrine disruptors during foetal development has been linked to an increased risk of obesity, diabetes, and cardiovascular disease later in life. Additionally, endocrine disruption can impact the thyroid, leading to thyroid disorders and potentially affecting metabolism, growth, and development.

The impact of endocrine disruption on human health is a growing area of concern, and more research is needed to fully understand the scope and magnitude of the problem. However, it is clear that endocrine disruption is a significant health risk associated with ocean pollution. Addressing ocean pollution and reducing the release of endocrine disruptors into the environment is crucial for safeguarding human health and protecting vulnerable populations.
