Probably the Drake Passage, south of Cape Horn; they're stormy year-round:\n\nhttp://en.wikipedia.org/wiki/Drake_Passage

the most dangerous animal in the world that destroys the Environment and kills all the animals is called Homosapian.\n\nthey are now classified as being an invasive plague to the planet ,if you observe their devellopment from space.\n\nthe most dangerous animal that has killed the most people or homosapians ,is the hippopotamus ,because man has invaded and shrunk their habitats.\n\nLions in central Africa hunt and kill a lot of people ,because poverty has made the people kill all the game of,and the lions are short of food,but the hippo´s still have killed the most.

Also not mentioned... almost anywhere there's water.  That includes the upper atmosphere, the air you breath, living inside of plants and even cells, antartica, from the bottom of the ocean to the surface, in everything you eat, inside rocks; the list goes on.

Yup, definately oceans.

Because there is a bloody big ocean in between!

Hurricanes, earthquakes, mud-slides...natural disasters. Not to mention, we think we're the biggest, badest things on earth. The top of our food chain. Yeah. Right. Go swimming in the ocean w/ sharks. That's a really good way nature teaches us we aren't all that.

Probably the Asian tsunami

Japan.\n\nThey still send out whaling ships to kill whales.\n\nKeep in mind, that just because it is illegal in some countries to kill whales and dolphins, it doesn't mean that it doesn't happen. People just don't get caught. Or, sometimes they are accidentally killed in fishing nets.

East China Sea, South China Sea, Sea of Japan, Phillipine Sea, Java Sea, Greenland Sea, Sea of Galilee, and the Indian Ocean

Istanbul. It depends on what you consider to be sea as there is no city literally split in half by deep ocean. If you consider any navigable saltwater strait that connects two sea sized bodies as "divided by sea" then Istanbul is divided by sea. The Black and Mediterranean Seas are connected by the Bosphorus, a strait around 1 mile wide.\nI really can't think of any others at the moment.\nCopenhagen is on a strait, maybe if Malmo,Sweden is considered a suburb then that too.

East Coast is safer.\n\nWest Coast has a lot of really big Volcano's and we are waiting for an Earth Quake called "The Big One"

Defining the world's most dangerous sport remains a tricky subject, mainly due to limited data: Unsurprisingly, organizers and participants are loath to publicize deaths. (Existing information produces curious results. In the U.K., for example, angling kills more people each year than any other sport, due to drowning, but it is by no means deemed extreme.) The key is not the death toll but what the worst-case scenario is if something goes wrong.\n\n    Which do you think is the most dangerous? \nBASE Jumping \nBull Riding \nHeli-Skiing \nStreet Luging \nBig-Wave Surfing \n \nView Results \nReply \n \nBroadly speaking, if an activity involves being exposed to the elements, using specialist equipment to control an inherently incontrollable and unpredictable environment, it is probably an extreme sport. Cave diving in dank, enclosed spaces qualifies, as does surfing 50-foot waves capable of destroying a small village. \n\nSuch activities, loosely defined as extreme or dangerous sports, are not for everyone. They tend to attract men (though not exclusively) in their late 20s to early 40s, who live for the moment--which is a good thing since it could always be their last. Even without death, there's a long list of injuries on offer: from concussion or brain damage (bull riding) to broken bones (luging, among others), frostbite (mountaineering) or the bends (scuba diving), to name a few. \n\nSo why do it? As Harry Parker, a BASE jumper, says incredulously: "Why? Because you can!" But the bottom line is this: People will go to extraordinary lengths to get high. If this means splashing out over $600 per day to heli-ski by jumping from a helicopter into virgin snow, and risk starting an avalanche, all the better. \n\nBut besides the adrenaline junkies are what the Speleological (the Latinate term for caving) Society dubs "equipment junkies." They love the associated paraphernalia and experimenting. A notorious experimenter is David Kirke, the founder of England's Dangerous Sports Club. Most recently Kirke adapted the trebuchet, a medieval device for throwing rocks, to catapult humans from zero to 55 feet in the air in 1.9 seconds. By taking things to extremes, he says, it puts the rest of life into perspective. As Einstein would say, it's all relative. \n\nHuman curiosity, it seems, is as alive today as in the 1970s when Californian kids hit the open road by lying down on their skateboards and "butt-boarding," arguably one of the earliest extreme sports. The difference today from when these sports first started is that organizations and sponsors such as Red Bull, the energy drink, have turned formerly counterculture pastimes into moneymaking industries with regular televised events, offering prize money and endorsements. The Billibong Odyssey offers $100,000 for the first surfer to ride a 100-foot wave.

I learned it's the Tethys Sea, but Wiki has it as an ocean.  My second link calls it the Tethys Sea.
