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.

Under the highest-emission scenario, many countries would see substantial reductions in seafood available from exclusive economic zones by 2050. [1]Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, [2] ocean acidification [3] and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in ...

The report states that, due to human impact on the environment in the past half-century, the Earth's biodiversity has suffered a catastrophic decline unprecedented in human history, [3] as an estimated 82 percent of wild mammal biomass has been lost.
The United Nations Environment Programme (UNEP) mapped the impacts of stressors such as climate change, pollution, exotic species, and over-exploitation of resources on the oceans. The report shows at least 75 percent of the world's key fishing grounds may be affected. [27] [28] [29]
An oil spill in the fishing village of Kegbara-Dere, Rivers State on the Niger Delta. In 2016 Shell paid US$80 million for the spill [1] Petroleum extraction in the Niger Delta has led to many environmental issues. [2] [3] The delta covers 20,000 km 2 (7,700 sq mi) within wetlands, formed primarily by sediment deposition.
The environmental impact of fishing includes issues such as the availability of fish, overfishing, fisheries, and fisheries management; as well as the impact of industrial fishing on other elements of the environment, such as bycatch. These issues are part of marine conservation, and are addressed in fisheries science programs.
