Over 50 Percent Of Oceanic Shark Species Threatened With Extinction

"The first study to determine the global threat status of 21 species of wide-ranging oceanic pelagic sharks and rays reveals serious overfishing and recommends key steps that governments can take to safeguard populations. These findings and recommendations for action are published in the latest edition of Aquatic Conservation: Marine and Freshwater Ecosystems."
Scientists determined that 16 out of the 21 species of sharks that live in the oceans, get caught by fishers, and that they can get extinct really easily, because when they catch them, the catches are not regulated.
They are vulnerable to be over fished, because a lot of times they don't reach the age in which they are sexually mature and have offspring. So the population of sharks can go down easily.
"Fishery managers and regional, national and international officials have the opportunity and the obligation to halt and reverse the rate of loss of biodiversity and ensure sharks and rays are exploited sustainably." says lead author Nicholas Dulvy from the Centre for Environment.
"The current rate of biodiversity loss is ten to a hundred times greater than historic extinction rates, and as humans make increasing use of ocean resources it is possible that many more aquatic species, particularly sharks, are coming under threat," says Dulvy
So some of the solutions for this problem are to establish limits for catching them, so that the sharks can be controlled.

I really like everything about marine life, so I think that this is a problem that has to stop, because all fish and sharks are going to be extinct if this doesn't stop.
So if this doesn't stop soon, it can happen faster than anyone can think.
More other things consequences can happen because if sharks get extinct, they can stop the food chain, and then more problems will come on and on and on, so it is important that it stops.
And besides animals don't have the fault from anything, the fishers are the ones that are making mistakes sometimes not really knowing, so I think that authorities should really put an end to this.
