The 2007 film Sharkwater documents ways in which sharks are being hunted to extinction. [15] In 2009, the IUCN Shark Specialist Group reported on the conservation status of pelagic (open water) sharks and rays. They found that over half the pelagic sharks targeted by high-seas fisheries were threatened with extinction. [16] [17] [18]
Overfishing of sharks has increased as the global demand has skyrocketed in recent years. Sharks are hunted for their meat, skin, cartilage, fins, livers, and teeth.
Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks, has led to the upset of entire marine ecosystems. [1] Types of overfishing include growth overfishing, recruitment overfishing, and ecosystem overfishing.
Their role keeps the environment healthy because "they usually go after the sick, weak and slower fish populations." Due to shark overfishing in many areas in the world sharks are going missing or endangered. [31] In 2013, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) listed the vulnerability of sharks.
Some scientists have argued that proposing to kill sharks to stop depredation is missing the point, noting that overfishing of shark’s prey species can cause them to bite fish already on someone ...

Due to intense overfishing in the area, the scalloped bonnethead is the rarest of all hammerhead sharks. They prefer the tropical waters of the eastern Pacific Ocean between Mexico and Peru.
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]
