Everyday our brave troops and their families stand up for us. For years, we’ve asked so much of so few. Now we have a chance to serve these heroes to give time, offer comfort, or lend a hand.
to ease the burden on a military family. Let’s honor their service by volunteering ours.
Now CNN’s Anderson Cooper on assignment for 60 Minutes. There’s no animal that we fear more and understand less than the great white shark. In part because it's so hard to get near them, studying great whites hasn't been easy. But there is one man who has spent his life getting closer to great whites, more often than anyone else. His name is Mike Rutzen and in South Africa, where he lives, he's known simply as The Shark-man. What he’s discovered about these predators will surprise you, far from being mindless어리석은 killing machines, Rutzen believes great whites are smart, curious, and not out to kill humans. And as you’re about to see, he’s willing to risk his life to prove it.
Mike Rutzen is looking for a great white shark he can swim with. That's right, swim with. Before he gets in the water, he needs to find a great white that’s both calm and curious. Rutzen says great whites have personalities. They may be the top predator in the sea, but he says, they are not the man-eating killers of our nightmares. This shark and several others have been attracted to Rutzen's boat by chum친구, a mixture of bait and fish blood. It's believed great whites can smell a single drop of blood from 100 yards away.
Now that he's found a player, Rutzen and his cameraman Morne Hardenberg suit up and prepare to do the unthinkable, plunge into bloody water with great white sharks all around. Immediately, a curious great white comes straight at Rutzen. His only protection… his camera. Rutzen has figured out that great whites don't like the feel of metal. Good visibility is crucial. The sharks are constantly circling. And Rutzen has to continually turn around, so they don't sneak up on몰래 접근하다 him.
Rutzen is not a scientist. He was born on a farm and knew nothing about sharks until 20 years ago when he began working as a fisherman along this rugged coast near Cape Town. These waters are home to the world's highest concentration of great whites. A perfect hotspot because it's an ideal feeding ground for great whites. It's not far from the southern tip of Africa where the Atlantic and Indian Oceans meet. The water is rich in nutrients영양분 which attract whales, huge shoals떼 of fish and seals, some 60,000 of them. Seals are a prime target for great whites. The sharks leap straight out of the water, stunning the seals before devouring them. Seals are mammals, they're quick, agile날렵한, and smart, but as Rutzen has learned, they are no match for the power, speed, and intelligence of the great whites.
