Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
At this point, the more effective method of combating ocean pollution is keeping it from reaching the ocean to begin with through waste management and legislation to prevent further pollution . Some research has shown that certain bacteria could naturally consume plastics, but more studies are needed.
The Garbage Patch State – Wasteland is an ongoing transmedia, environmental artwork by Maria Cristina Finucci.The project aims to raise awareness about the environmental hazard of the Great Pacific Garbage Patch caused by the dispersion of plastic debris in the oceans.
Overview of climatic changes and their effects on the ocean. Regional effects are displayed in italics. [1] This NASA animation conveys Earth's oceanic processes as a driving force among Earth's interrelated systems. There are many effects of climate change on oceans. One of the most important is an increase in ocean temperatures.
While marine pollution can be obvious, as with the marine debris shown above, it is often the pollutants that cannot be seen that cause most harm.. Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there.
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 Clean Ocean Foundation is an Australian environmental organisation that seeks to stop all forms of ocean pollution and restore our oceans to their former health.. Clean Ocean Foundation holds that the best way of minimising the impact of the waste from any land-based activity is for the waste to be retained on land wherever possible so its impact can be properly monitored and minimised.
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.
