Sharks have lengthy impressed our fascination and our concern. Nonetheless, a rising physique of scientific proof has proven that as an alternative of being afraid of sharks—which have killed fewer people inside a yr than such dangers as accidents taking scenic selfies and encounters with merchandising machines—we must be afraid for sharks. The most recent numbers from the Worldwide Union for Conservation of Nature’s Pink Record present that almost one third of all recognized species of sharks and their kin are thought-about threatened with extinction. This is among the highest charges of any vertebrate group. And since sharks play essential roles within the marine and coastal ecosystems that billions of people rely on for his or her livelihoods and meals safety, the duty of conserving these superb and misunderstood species ought to concern us all.

Extra individuals than ever earlier than are conscious of the shark conservation disaster and wish to assist, which is nice information. Nonetheless, many well-intentioned individuals typically don’t know the true causes of—and options to—this disaster, leading to what’s at greatest wasted effort, and at worst harming what they’re attempting to assist. This conservation dilemma has impressed the final decade of my analysis and public science engagement. It additionally impressed my new e-book, Why Sharks Matter: A Deep Dive with the World’s Most Misunderstood Predator, which synthesizes a whole lot of analysis papers and stories to tell readers of the true threats to sharks and the way we are able to start to unravel them. Solely by following the proof and searching for data-driven, sustainable options to overfishing can we save these fascinating and vital creatures.

Many individuals consider that the most important or solely menace to sharks is “shark finning”: the follow of catching sharks, harvesting their fins and discarding the carcasses at sea. However this isn’t the case and hasn’t been for many years. I’ve seen some on-line petitions calling for bans on shark finning inside Florida waters get tens of hundreds of signatures. Apparently neither the petition creators nor the numerous signatories are conscious that we already banned shark finning throughout the US virtually 30 years in the past. Whereas supporters of those petitions say that they’re “elevating consciousness,” it doesn’t assist anybody or something to share incorrect info about what the issues are or the way to resolve them. Such feel-good options do nothing whereas diverting vitality, media protection and funding away from options that may actually assist.

The best menace dealing with sharks—opposite to viral campaigns I’ve seen from well-meaning however uninformed supporters of shark conservation—isn’t local weather change, which can negatively have an effect on some populations, nor plastic air pollution, which can hurt some people however isn’t a species-level menace. We should always completely work to handle these two in addition to myriad different ocean conservation points, however claiming that doing so is important to shark conservation is at greatest deceptive.

In actuality, the highest menace to sharks and their kin, by far, is unsustainable overfishing, which incorporates, however isn’t restricted to, shark finning. 100% of the shark species thought-about threatened with extinction by the IUCN Pink Record, embody overfishing amongst their threats; it’s no accident that the paper saying Pink Record standing updates is entitled “Overfishing drives over one-third of all sharks and rays towards a world extinction disaster.” The issue is that people are killing too many sharks, whether or not by chance by way of “bycatch,” when individuals fishing seize different species swimming close to their fishing targets, or on function, both from finning, nevertheless small a share it might be, or due to a rising demand for shark meat. Banning or limiting the fin commerce alone does little to handle this a lot broader problem, and since there is no such thing as a standardization in how numbers of by chance killed sharks are reported, we nonetheless don’t actually know the depth of the issue.

Notably, this doesn’t imply that the one answer is “no fishing allowed ever.” Sustainable fisheries for sharks completely exist and are an important a part of livelihoods and meals safety in growing nations within the World South. Sharks have comparatively few offspring comparatively sometimes, which complicates fisheries administration, however the precept is similar as for any sustainable fishery: carry out scientific analysis to study what number of sharks are current, and permit fishermen to take a few of them (however not so many who the inhabitants collapses). In actual fact, 90 p.c of surveyed shark scientists and 78 p.c of surveyed shark conservation advocates desire sustainable shark fisheries to complete bans on fishing for sharks and commerce in shark merchandise!

In case you’ve by no means heard about sustainable shark fisheries earlier than however have heard that the easiest way to save lots of sharks is by banning the U.S. fin commerce, it’s in all probability as a result of, for causes that aren’t very clear, such bans get a lot, far more media consideration than science-based sustainable fisheries administration. Many individuals are additionally influenced by provocative and deceptive (to place it mildly) “documentaries” like 2021’s Seaspiracy.

There’s little doubt that sharks want our assist, and that the lack of sharks could be ecologically and economically devastating. However we should focus our efforts on the actual threats, and we should use evidence-based options to alleviate these threats.

If you wish to study extra concerning the threats to sharks and the options backed by knowledgeable scientists and scientific proof, I invite you to select up a replica of Why Sharks Matter: A Deep Dive with the World’s Most Misunderstood Predator.
