The types of marine pollution can be grouped as pollution from marine debris, plastic pollution, including microplastics, ocean acidification, nutrient pollution, toxins and underwater noise. Plastic pollution in the ocean is a type of marine pollution by plastics , ranging in size from large original material such as bottles and bags, down to ...

The ocean is currently suffering from the impacts of human damage including pollution, acidification, species loss, and more. This could prove particularly catastrophic given that the ocean takes up the largest part of the planet and serves as the home to many organisms, including the algae that provides around half of the oxygen on Earth.

A practical definition of water pollution is: "Water pollution is the addition of substances or energy forms that directly or indirectly alter the nature of the water body in such a manner that negatively affects its legitimate uses." [1]: 6 Water is typically referred to as polluted when it is impaired by anthropogenic contaminants.
“The Southern Ocean is very stormy in general (but) in the Drake you’re really squeezing (the water) between the Antarctic and the southern hemisphere,” he adds. “That intensifies the ...
With primary causes being warming ocean waters, ocean acidity, and pollution. [148] In 2008, a worldwide study estimated that 19% of the existing area of coral reefs had already been lost. [ 149 ] Only 46% of the world's reefs could be currently regarded as in good health [ 149 ] and about 60% of the world's reefs may be at risk due to ...
The importance and primary objective of a sanctuary is to protect its features and allow the ocean to be used in a natural and sustainable way. [4] Sanctuaries provide a safe haven for endangered species, or those close to extinction, while also serving educational purposes for students and researchers alike to promote understanding and ...
Warm water corals are clearly in decline, with losses of 50% over the last 30–50 years due to multiple threats from ocean warming, ocean acidification, pollution and physical damage from activities such as fishing, and these pressures are expected to intensify. [97] [82]: 416
