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.
Many humans consume many types of marine fish that are top predators in the food chains, putting their health in great danger. Therefore, finding possible solutions to minimize further mercury emissions and clean up the already existing mercury pollution is extremely important.
Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Plastic pollution is harmful to marine life. Another concern is the runoff of nutrients (nitrogen and phosphorus) from intensive agriculture, and the disposal of untreated or partially treated sewage to rivers and subsequently oceans.
Fortunately, there are solutions to protect corals and coral reefs against the harmful effects of plastic pollution. However, since little to no research exists regarding specific medicinal ways to help corals recover from plastic exposure, the best solution is to not let plastics enter the marine environment at all.
Researches on marine debris have substantially increased our knowledge of the amount and composition of marine debris as well as its impacts on the marine environment, aquatic life and people. [7] Marine debris is very harmful to marine organisms such as plants, invertebrates , fish , seabirds , sea turtles and other large marine mammals .
The United States is investing in marine energy technology to help meet clean energy goals, with the Marine Energy Technologies Acceleration Act providing $1 billion for research, demonstration ...
Plastics accounts for 80% of waste dispersed in the marine and coastal environment of the Mediterranean Sea. [24] Recent studies focus on the types of plastics found and primarily on the issue of microplastics, both at a global but also at a regional level, as in the case of the Mediterranean Sea, which was identified as a "target hotspot of the world" due to its amounts of microplastics ...
The United Nations Environment Programme (UNEP) created The Global Programme of Action for the Protection of the Marine Environment from Land-based Activities to protect marine ecosystems. [15] They also passed the International Convention for the Prevention of Pollution from Ships in 1973 to prevent ship-based pollution to the ocean.
