The Dangers of Scuba Diving and Underwater Exploration Essay

Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind, some private as well as national organizations have accepted the challenge of educating and informing people about the existence of the shark specie and its importance to the sea.

This organism causes the sharks to go blind. Luckily Greenland sharks are mainly scaevngers and heavily rely on their heighted sense of smell.

First of all, ocean exploration technology has advanced much more than before in the past decade. In the past, people had to bring everything needed for scuba diving which included hundreds of pounds of gear and photographing technology. Now, all

The second Phase is basically based on diving and life saving maneuvers underwater. Many times this phase sets back many students, which means they must go through these tactics over and over until they pass. During these 7 weeks you will learn about the underwater explosive device and how and where to attach it to a ship. You can expect to conduct close to fifty dives during this period of training. This course will teach you many things about submarines and how to escape them if necessary. It also teaches you a lot of surviving skills that are mandatory for an everyday life as a Seal. Once you have completed this Phase

Every animal is important, but sharks are very high up on the list of animals that humans need to protect and save. Without them, our ocean’s ecosystem and coral reefs would be decimated and humans would take a dramatic hit in terms of what we ate and fished. Sharks keep the ocean’s population in check and make sure that there are enough of their prey to sustainably eat while giving us seafood such as scallops and clams. Just because an animal looks scary does not mean that we should be uncaring about its wellbeing and

Have you ever been on vacation and was scared to go into the ocean because of sharks? Since many people are unaware of the potential danger of the ocean, they would be enlightened to know about the deadliest sharks, ways to prevent attacks and even about Bethany Hamilton’s horrific story!

They call the "finders keepers" concept and stipulates that since they found the artifact they should be the rightful owner of those objects. When you dive, the underwater pressure squeezes your internal organs in an unnatural way that many divers claim to be the holder since they put their heath at risk when they fetch the treasures. This is not an act of bravery but one blinded a quest for money and

He doesn’t dive anymore de to health problems. He has a compressed disk in his neck, and he spent most of his time on the surface constructing; so he was out of shape. Right now he works on a 300ft. Construction boat.

Thesis/main topic – Learning how to swim is essential for being around water, it will help strengthen a person confidence, improve your physical fitness, and provide an area for stress release.

Sharks were always thought to be brainless ferocious killers of the sea. Very large parts of the brain are dedicated to just their smell! Hammerheads have the most productive brains because they feed on animals under the sea dirt. Sharks are streamlined swimmers, ferocious hunters, and meat eaters.

Sharks are interesting fish because they don’t really mean to eat humans. Everyone says how scary they are but I think if you stay out of their territory they wouldn't feel threatened. In some places sharks have become an important tourist

aka white sharks, white pointers, blue pointers, man-eaters, manila sharks, have, according to E. O. Wilson "...rightfully been called a top carnivore, a killing machine, the last free predator of man—the most frightening animal on earth.“Three were young sharks, which could not have travelled far from their birth place, confirming active nurseries in the Mediterranean. The mitochondrial DNA controls some regions that were by established by the ancestors of the Great White sharks.Some of them might come from from the Atlantic populations but from Pacific Australia and New Zealand. Sharks external ears are very hard to see, they only have just two small openings behind and above the eyes. The ears may be small, but they’re powerful. Inside, the cells can sense even the tiniest vibration in the water around them. Sharks also have an ‘ear stone’ that gives the animal clues as to where the others are in the water:.”The time, 450,000 years, suggested very few white sharks may have made a navigational error by following extensive of an exceptionally strong current, which at this time penetrated the cooler .The Benguela current goes farther north and west than at present. Sharks who swim east and north would have become entrapped in the Mediterranean, where natal philopatry of young would ensure population continuity. Potentially isolated Mediterranean white sharks propagate from a small founding

Sharks hunt for food in a variety of ways. From the blood sniffing style of the Great White to the ambush tactics of the Goblin shark, they all needed to catch their food somehow.

If a shark sees a human splashing in the water, it may try to investigate, leading to an accidental attack. Still, sharks have more to fear from humans than we do of them. Sharks are a hot commodity throughout the world and their population is steadily declining due to long gestation periods and overharvesting of the animals by fishermen. “Humans hunt sharks for their meat, internal organs, and skin in order to make products such as shark fin soup, lubricants, and leather.” Rates of reproduction are low among

Before this unit began I was not aware of what the rules surrounding dive flags were or what dive flags looked like. I now know that dive flags are blue and white and boats must keep a 50-meter limit of approach to a dive flag and a speed limit of 4 knots. I was not aware that there were 10 specific snorkel safety rules that needed to be followed whilst snorkelling. These 10 snorkel safety rules were learnt during this unit. The rules
