The Caribbean's coral reefs have been increasingly becoming diseased by 20 percent. [19] Coral diseases can cause tissue damage or it could even destroy the entire colony. [19] In 1980, white-band disease killed 95 percent of the Acroporid palmata and Acroporid cervicornis colonies which placed them on the Endangered Species Act. [15]
In the Caribbean, white band disease is one of the primary causes for the death of over eighty percent of Staghorn and Elkhorn coral (Reef Resilience). It is a disease that can destroy miles of coral reef fast. A disease such as white plague can spread over a coral colony by a half an inch a day.
Overfishing is occurring in one third of world fish stocks, according to a 2018 report by the Food and Agriculture Organization of the United Nations. [9] In addition, industry observers believe illegal, unreported and unregulated fishing occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries. [10]
Overfishing is one of main causes of the decrease in the ocean's wildlife population over the past years. The Food and Agriculture Organization of the United Nation reported that the percentage of the world's fish stocks that are at biologically sustainable levels have decreased from 90% in 1974 to 65.8% in 2017.
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 African penguin joins the list of species said to be threatened by climate change - and overfishing. Researchers from the UK and South Africa say penguin numbers in the Benguela upwelling ...
A 2019 Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services report found that overfishing is the main driver of mass species extinction in oceans. [142] [143] Overfishing has reduced fish and marine mammal biomass by 60% since the 1800s. [144] It is currently pushing over one-third of sharks and rays toward ...
