Marine systems refer to the complex networks of living organisms and their physical environment in oceans and seas. These systems include various habitats such as coral reefs, estuaries, and open ocean areas, each supporting diverse marine life. Key components of marine systems include water, sunlight, nutrients, and the organisms that inhabit these environments, such as fish, marine mammals, and plankton. The health of marine systems is crucial for global ecosystems and human economies. They provide essential services, including fisheries, carbon storage, and coastal protection. However, marine systems face threats from pollution, climate change, and overfishing, which can disrupt their balance and biodiversity.
