“Beginning in 2008, the International Union for Conservation of Nature (IUCN) classified ten shark species as critically endangered (extremely high risk of extinction). Nine shark species are classified as endangered (very high risk of extinction), thirty one shark species as vulnerable (high risk of extinction) and sixty three shark species as near threatened”

Remove the predators, and the whole ecosystem begins to crash like a house of cards. As the sharks disappear, the predator-prey balance dramatically shifts, and the health of our oceans declines.

"... If you’re lucky enough to see lots of them, that means that you’re in a healthy ocean. You should be afraid if you are in the ocean and don’t see sharks. – Sylvia Earle

Number of shark attacks and deaths per year

"Back in 1950, the global population was 2.5 billion people. Today it’s just over 8 billion... [for] the rate of unprovoked shark attacks per million people... things stay pretty flat, with 0.012 per million in 1950 and 0.010 in 2020.”

Likelihood of shark attack compared to other things

French fries kill more people than guns and sharks, yet nobody’s afraid of French fries. – Robert Kiyosaki

More likely to get killed by:

• champagne corks
• a ladder
• falling out of bed

than be killed by a shark

They don't want to kill you, just figure out what you are.

Most sharks are not dangerous to humans — people are not part of their natural diet.

Sharks have been known to attack humans when they are confused or curious. If a shark sees a human splashing in the water, it may try to investigate, leading to an accidental attack.

“The juvenile white sharks were often observed within 50 yards of where the waves break, putting surfers and stand-up paddle boarders in the closest proximity to sharks at the aggregation sites,” Patrick Rex, a lab technician at the Shark Lab, said in a statement... “People think, ‘If I see a shark in the lineup (the area where waves begin breaking), I’m going to get bitten or I’m in danger.’” Rex said. “And what we’ve seen is that that’s not necessarily the case.”

The fish “tend to mind their own business,” Rex said. “And they come up within like 10 feet of people,

and that’s happening daily,” he said. “What we found is that they’re spending the majority of their

time within 100 yards of where the waves are breaking.” That’s a lot closer than originally thought.

“It was assumed that sharks are miles out but you could be wading and then have a shark swim

right next to you,” he said.
