Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.
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]

This prompted major amendments in 1996 and 2006. The National Marine Fisheries Service issued a report to Congress in 2010 on the status of U.S. fisheries. It reported that of the 192 stocks monitored for overfishing 38 stocks (20%) still have fish "mortality rates that exceed the overfishing threshold … and 42 stocks (22%) are overfished". [12]
The number of fish on the government's overfishing list sunk to a new low last year in a sign of healthy U.S. fisheries, federal officials said. The National Oceanic and Atmospheric Administration ...
[243] [244] There are anecdotal reports of negative health effects on people who live very close to wind turbines. [245] Peer-reviewed research has generally not supported these claims. [246] [247] [248] Pile-driving to construct non-floating wind farms is noisy underwater, [249] but in operation offshore wind is much quieter than ships. [250]
Overfishing (2006 Pilot Environmental Performance Index) Although there is a decline of fisheries due to climate change, a related cause for this decrease is due to over-fishing. [ 58 ] Over-fishing exacerbates the effects of climate change by creating conditions that make a fishing population more sensitive to environmental changes.
One indicator (14.1.1b) under Goal 14 specifically relates to reducing impacts from marine plastic pollution. [ 3 ] According to the 2020 report on progress towards the Sustainable Development Goals, "current efforts to protect key marine environments and small-scale fishers and invest in ocean science are not yet meeting the urgent need to ...
