Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines , frequently washing aground, when it is known as beach litter or tidewrack.

There are three primary ways the public can learn about or participate in beach cleaning: educational programs, awareness campaigns, and volunteering. All modes of public engagement can increase awareness of the issue of marine litter, educate participants about marine litter and ocean conservation, and motivate behavior change.
The U.S. alone spends about $11.5 billion every year cleaning up litter, according to Keep America Beautiful — and that number seems likely to keep growing thanks to COVID-19. Read: 16 Companies ...
[62] [63] Tropical cyclones use warm, moist air as their source of energy or fuel. As climate change is warming ocean temperatures, there is potentially more of this fuel available. [64] Between 1979 and 2017, there was a global increase in the proportion of tropical cyclones of Category 3 and higher on the Saffir–Simpson scale.
[49] [50] Scientists realized over 30 years ago the ocean was a key fingerprint of human impact on climate change and "the best opportunity for major improvement in our understanding of climate sensitivity is probably monitoring of internal ocean temperature". [51] Marine organisms are moving to cooler parts of the ocean as global warming proceeds.
Currently the state of our oceans are declining due to climate change factors and human behaviour. [6] The deterioration of coastal waters is increasing due to both pollution and coastal eutrophication. Similar factors contribute to climate change, negatively affecting the oceans and marine biodiversity which is slowly declining. [7]
Drawing on the latest scientific knowledge, this chapter explains the relationships between CO 2 uptake by the ocean, climate change and the associated risks to the ocean ecosystem. Oxygen depletion, ocean acidification, sea-level rise and the loss of marine biodiversity as a consequence of climate warming are also explained.
