Mangrove loss continues due to human activity, with a global annual deforestation rate estimated at 0.16%, and per-country rates as high as 0.70%. Degradation in quality of remaining mangroves is also an important concern. [2] There is interest in mangrove restoration for several reasons. Mangroves support sustainable coastal and marine ecosystems.
Mangrove forests live at the interface between the land, the ocean, and the atmosphere, and are centres for the flow of energy and matter between these systems. They have attracted much research interest because of the various ecological functions of the mangrove ecosystems, including runoff and flood prevention, storage and recycling of ...
Ocean deoxygenation is an additional stressor on marine life. Ocean deoxygenation is the expansion of oxygen minimum zones in the oceans as a consequence of burning fossil fuels. The change has been fairly rapid and poses a threat to fish and other types of marine life, as well as to people who depend on marine life for nutrition or livelihood.
A natural resource may exist as a separate entity such as freshwater, air, or any living organism such as a fish, or it may be transformed by extractivist industries into an economically useful form that must be processed to obtain the resource such as metal ores, rare-earth elements, petroleum, timber and most forms of energy.
The term was popularized through Sustainable Development Goal 14 which is about "Life below water" and is one of the 17 Sustainable Development Goals established by the United Nations in 2015. The official wording of the goal is to " Conserve and sustainably use the oceans, seas and marine resources for sustainable development ".
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.
She conveyed the sense that she was the living ocean…” [8] [9] In 2010, over 100 scientists, business leaders, philanthropists, and entertainment icons came together to support Dr. Sylvia Earle ’s Mission Blue wish and the following year, Gigi Brisson founded a group of Ocean Elders with the goal of unifying scientists with government and ...
Contributing between 1 and 10% of total ocean primary productivity, 200 species of coccolithophores live in the ocean, and under the right conditions they can form large blooms. These large bloom formations are a driving force for the export of calcium carbonate from the surface to the deep ocean in what is sometimes called “Coccolith rain”.
