Marine environments refer to the vast ecosystems found in oceans and seas, covering about 71% of the Earth's surface. These environments include various habitats such as coral reefs, open ocean, and deep-sea trenches. They are home to a diverse range of organisms, from tiny plankton to large whales, all of which play crucial roles in the marine food web. The health of marine environments is vital for global biodiversity and human well-being. They provide essential resources like fish, which are a primary food source for billions of people, and they help regulate the Earth's climate by absorbing carbon dioxide. Protecting these ecosystems is important for sustaining life on our planet.
