CNN: Climate Change is Driving Fatal Shark Attacks

Guest essay by Eric Worrall

According to CNN, climate change is making sharks more desperate by destroying the ecosystems that feed them, leading to an increase in deadly shark attacks on humans.

Sharks have killed 7 people in Australia this year, most since 1934. Climate change could be a factor

(CNN) One morning in early October, a now familiar scene unfolded on a beach in Western Australia.

A shark had attacked a missing surfer. Authorities sent drones into the sky to monitor the air, rescue workers jumped on boats to search the area, and medics waited ashore.

Days of search uncovered the man's surfboard, but his body was never found. He was counted as the seventh victim of a shark attack in Australia that year – an alarming spike that has not been seen in the country for 86 years.

There are a number of possible explanations – Several experts have suggested that the numbers fluctuate from year to year and this could just be bad luck. But there is another possible culprit: the climate crisis.

As the oceans warm up, entire ecosystems are being destroyed and have to adapt. Fish migrate where they have never been before. The behavior of the species is changing. And as the marine world changes, sharks follow their prey and approach the shores popular with humans.

One possible solution could be to dilute their numbers. But shark culls are becoming more and more difficult to organize; Australia's greens often agitate against the eradication of sharks.

Why sharks shouldn't be killed to keep surfers safe

The senator explains to parliament why sharks should not be killed

September 7, 2015

Last month, Tasmanian Green Senator Peter Whish Wilson, who is an avid surfer, used a speech in Parliament to oppose shark eradication in response to recent attacks on the north coast.

Mr Whish Wilson described his position as unique in that he is "one who wants to save the creatures who may want to eat him". We are publishing his speech here as a contribution to the debate.

I have thought often and deeply on this subject. My conclusions are that the two most important things to a surfer like me are: First: understand the risks associated with surfing; and second, only go into the water if you accept the risks. You may still be dissatisfied with the acceptance of these risks – sharks are always on my head when I'm in the water – but it has to be your choice. As I just noted, the good news for marine enthusiasts is that the risk of unwanted shark encounters is statistically very small and can be reduced to some extent. But by any statistical measurement death by Hai y majority of modern humans.

Does clubs make a difference? I think it's likely they could. Although sharks are free to roam the entire ocean, the reality is that much of the ocean is a desert in terms of life. Ocean activity tends to be concentrated in nutrient-rich areas such as coastal margins, so sharks killed from one region may not necessarily be immediately replaced from a neighboring region.

Culling would likely make our beaches safer – if the culling program was continued.

On the climate front, I think the argument that climate change is making sharks wilder because they run out of food strengthens the argument for culling. Free the starving sharks from their misery – better for the sharks, better for people who want to use the beaches.
