Humans know how to swim with sharks, just like in Africa, people know how to chase lions.
Humans "know how to swim with sharks" when they have food to offer, and the humans aren't bleeding themselves - and even then, most often, cages are used. Yes, sharks, like most other animals, are fairly docile unless provoked, or are in need. Why do I have to explain any of this to you? Because you want to harbor ridiculous notions about "how much better" you are than any animal? It's foolishness. You should read this:
Worst shark attack
Hundreds of soldiers stranded in the water for days on end when their ship was struck by enemy torpedos. The sharks started showing up the morning after the attack and just milled about for a bit. As they began to understand that the humans they were swimming around weren't a big threat, they started taking bites. "HUMANS KNOW HOW TO SWIM WITH SHARKS." Are you seriously even trying when you make statements like this?
Oh, and ask the Africans if they just casually hang around lions. Do you seriously think they don't fear the creatures out of genuine respect? Yes, so what, we figured out how we can try and
protect ourselves from lions - because make no mistake WE NEED PROTECTION. We, as a species, are one of the most physically ill-adapted to surviving on Earth. Can't run quickly, can't withstand extreme cold, can't dig, can't fly, almost no way to attack or defend, can't smell worth a damn, many of us can't see to save our lives. We're soft, weak, slow, naked. The only thing we have going for us is the use of our intelligence - and even that isn't entirely ours, because a huge chunk of our knowledge and the comforts we enjoy as "methods of survival" now were passed on to us by the generations and generations of people who came before us and figured everything out so we wouldn't have to.
Get down off your high horse. Actually... just realize that your "high horse" is completely imaginary and stop running around pretending to ride. You are no better than any animal. Maybe you are to other humans... but nothing else recognizes you as such, and you need to realize that.
