Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
There hasn't been a megalodon shark in the ocean's waters since around 3 million years ago — and it roamed the seas for around 100 million years before that — but that didn't stop a Croatian ...

The Great Pacific garbage patch (also Pacific trash vortex and North Pacific garbage patch [9]) is a garbage patch, a gyre of marine debris particles, in the central North Pacific Ocean. It is located roughly from 135°W to 155°W and 35°N to 42°N. [10] The collection of plastic and floating trash originates from the Pacific Rim, including ...
Saving the planet's oceans from plastic pollution isn't on the agenda of a typical 12-year-old -- however, Anna Du is working to achieve just that. 12-year-old engineer invents device to combat ...
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 ]
Mercury can enter seas and the open ocean as a result of the down stream movement and re-deposition of contaminated sediments from urban estuaries. [12] For example, high total Hg content up to 5 mg/kg and averaging about 2 mg/kg occur in the surface sediments and sediment cores of the tidal River Mersey, UK, due to discharge from historical industries located along the banks of the tidal ...
Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...
