A study conducted by researchers Jeffrey S. Cooper, Erwin L. Kong and Heather M. Murphy-Lavoie, talked about the trauma that can be incurred from a shark attack. The study, titled Shark Trauma, told: "There are over 470 species of sharks throughout the world.
Their habitats include saltwater and freshwater alike. They generally prefer the shallows in temperate, tropical regions, which is usually where divers and surfers come into contact with them and potentially become the victims of shark trauma.
While this is a genuine threat to safety, it continues to remain statistically unlikely. Nevertheless, for those shark attacks that do occur, they become increasingly more perpetuated secondary to the level of mutilation achieved from even a singular bite.
The wounds sustained from a shark bite have not been shown to follow any singular disease course or bacterial growth pattern. Even when non-fatal, massive blood loss, amputation, and vital organ puncture can occur. Even though sharks have not become more aggressive over the years, the incidence of shark attacks is increasing, thought to be due to the rise of water activity by people within the sharks ’environment." Most global fisheries are not, or to a mild extent, monitored and regulated.
There has recently been an increase in demand for shark-related products and at the same time the proportions of the fishery have increased. As a result, the population of various species is rapidly declining because sharks are super predatory animals with a long life span and relatively small populations.
For these reasons, mating aimed at maintaining sufficient numbers for survival is difficult. Some species have experienced a 90% decline and it is not difficult to find many that have decreased by 70% in number. Many United Nations governments have fortunately acknowledged the problem, but given the low economic interest linked to these animals in Western countries and the bad reputation they enjoy, little progress has been made.
Other major threats to shark survival include severe alterations to their natural habitat, damage due to urban development on the coasts, pollution and the impact of fishing on the bottom species that are typically prey to these fish.
The violent practice of cutting the fins, linked to the preparation of shark fin soup and mentioned in the previous paragraph, has given rise to many discussions and regulations aimed at preventing it. The acclaimed 2007 documentary Sharkwater explained how several species have been driven to near extinction following huge demand in some Asian states for fin soup.
