The environment of the ocean encompasses the vast body of saltwater that covers over 70% of Earth's surface. It is a complex and dynamic system characterized by diverse habitats, including coral reefs, deep-sea trenches, kelp forests, and open ocean pelagic zones. These environments support an incredible array of life, from microscopic plankton to the largest whales, forming intricate food webs and ecosystems.

Ocean environments are shaped by numerous physical and chemical factors. Salinity, temperature, light penetration, pressure, and currents all play crucial roles in determining where and how organisms can survive. The ocean's chemistry, including dissolved oxygen levels and nutrient availability, is also vital for marine life. Ocean currents, driven by wind, temperature, and salinity differences, act as global conveyor belts, distributing heat, nutrients, and marine organisms across the planet.

Human activities have a significant impact on ocean environments. Pollution from land-based sources, such as plastics and chemical runoff, degrades water quality and harms marine life. Overfishing depletes fish populations and disrupts ecosystem balance. Climate change, primarily driven by greenhouse gas emissions, leads to ocean warming, acidification, and sea-level rise, posing severe threats to coral reefs, marine biodiversity, and coastal communities. Conservation efforts and sustainable practices are essential for protecting these vital global resources.
