Marine pollution caused by plastic substances is recognized as an issue of the highest magnitude, from a pollution perspective. [27] A majority of plastics used in people's day to day lives are never recycled. Single use plastics of this kind contribute significantly to the 8 million tons of plastic waste found in the ocean each year. [2]
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.
Ocean acidification is the increasing acidification of the oceans, caused mainly by the uptake of carbon dioxide from the atmosphere. [88] The rise in atmospheric carbon dioxide due to the burning of fossil fuels leads to more carbon dioxide dissolving in the ocean. When carbon dioxide dissolves in water it forms hydrogen and carbonate ions.
Plastic pollution is widely recognized as a critical global issue. It continues to overwhelm waste management systems, flooding plastic into our oceans, soil, air, and food chains, and raises ...
With primary causes being warming ocean waters, ocean acidity, and pollution. [3] In 2008, a worldwide study estimated that 19% of the existing area of coral reefs had already been lost. [ 4 ] Only 46% of the world's reefs could be currently regarded as in good health [ 4 ] and about 60% of the world's reefs may be at risk due to destructive ...
The Formosa steel plant is suspected to be the source of the toxic chemical waste. [6] The company admitted that there was a sewage pipe connecting the plant and the ocean and it was reported that several days before the incident, 300 tonnes (300 long tons; 330 short tons) of chemicals were imported by Formosa in order to clean the pipe.

Plastic pollution has also greatly negatively affected our environment. "The pollution is significant and widespread, with plastic debris found on even the most remote coastal areas and in every marine habitat". [77] This information tells us about how much of a consequential change plastic pollution has made on the ocean and even the coasts.
The collapse of the Atlantic Meridional Overturning Circulation (AMOC) would drop temps in the Northern Hemisphere by 40 degrees—ending life as we know it.
