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.
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.
The National Biodiversity Assessment (NBA) is recurring project by the South African National Biodiversity Institute in collaboration with the Department of Environmental Affairs and several other organisations to assess the state of South Africa's biodiversity over time as an input for policy and decision making where the environment may be affected.
Illegal, Unreported, and Unregulated (IUU) Fishing poses a global challenge and has significant economic and environmental repercussions. [5] The impact of IUU fishing includes economic losses, job losses, scarcity, price distortion, food insecurity and unfair competition, [6] together with the depletion of fish populations and damages to the marine habitat.

On a larger scale, illegal fishing in Africa takes place when vessels from foreign countries are stationed on African waters without any legal documentation that allows fishing. [ 2 ] [ 3 ] Illegal fishing in Africa is one of the main causes of overfishing, [ 4 ] and increases the spread of diseases. [ 5 ]
Ninety percent of Africa's population requires wood to use as fuel for heating and cooking. As a result, forested areas are decreasing daily, as for example, in the region of equatorial evergreen forests. According to the United Nations Environment Programme, Africa's desertification rate is twice that of the world's. [4] Deforestation of ...
Commercial fishing showing the abundance of fish species caught using a trawling method. Unsustainable fishing methods refers to the use of various fishing methods to capture or harvest fish at a rate that is unsustainable for fish populations. [1] These methods facilitate destructive fishing practices that damage ocean ecosystems, resulting in ...
Sustainability can mean different things to different people. Some may view sustainable fishing to be catching very little in order for fish populations to return to their historical levels (represented by the upper left green area), while others consider sustainability to be the maximum amount of fish we can catch without depleting stocks any further (red dot).
