The marine environment refers to the collection of living and non-living organisms that exist in the world's oceans and seas. This includes a wide variety of habitats, from coral reefs and kelp forests to open ocean waters and deep sea trenches. Researchers studying the marine environment aim to understand the complex interactions between marine organisms and their surroundings, as well as the impact of human activities on marine ecosystems. This field of research includes studies on marine biology, oceanography, marine ecology, and marine conservation. Understanding and protecting the marine environment is crucial for maintaining biodiversity, supporting fisheries, and preserving the health of our planet.
