Oceans cover over 70% of the earth’s surface and play a crucial role in the health and wellbeing of humans. The air we breathe, the food we eat, and the medicines we rely on are all linked to the ocean.
Firstly, oceans are a major source of oxygen production. Phytoplankton, tiny plants that live in the ocean, produce half of the oxygen that we breathe. Therefore, the overall health of the ocean ecosystem is directly related to the air we breathe.
Secondly, fish and seafood are an important part of many people’s diets. The ocean is home to a plethora of different species of fish and seafood that are consumed by humans. The omega-3 fatty acids found in fish are essential for human brain function and have been linked to reducing the risk of heart disease and stroke.
Lastly, the ocean is a source of many medicines and other health products. For example, the anti-cancer drug, cytarabine, was derived from a sponge found in the ocean. Additionally, iodine, which is essential for thyroid function, is found abundantly in seawater.
Unfortunately, human activities are having a negative impact on ocean health. Pollution, overfishing, and climate change are all causing harm to the ocean ecosystem. This harm is in turn affecting human health and wellbeing.
In conclusion, the connection between oceans and human health cannot be overstated. Therefore, protecting the ocean and ensuring its sustainability should be a top priority for all of us.
