Scuba diving is a sport that has been done for centuries. Scuba stands for Self Contained Underwater Breathing Apparatus, in which people dive underwater with a cylinder of gas to breathe with the assistance of masks, fins, a breathing regulator, a buoyancy device, and gauges to explore the underwater environment. In the early nineteenth century new improvements were invented to help divers stay submerged underwater longer and have a smoother dive. But there is still doubt whether it is still safe to scuba dive or not because of the dangers that come with diving. And there are some areas of the world in which divers should be aware of. Even though improvements in technology made scuba diving safer by allowing humans to stay submerged longer periods of time, scuba diving should not be done, especially in particular regions of the world. A majority of dangers that come with scuba diving are caused by extreme water pressures. The very first scuba dives performed were in search for jewelry and very short until a way to breathe underwater for longer periods of time was invented. In order for the divers to stay submerged underwater longer, they used a hollow reed. Research shows that later on, “helmets were made of metal to withstand even greater water pressure and divers went deeper” (MarineBio.org 1). These improvements in technology gave divers a smoother dive, allowing them to enjoy more time submerged deeper in the ocean. Along with divers being able to stay under longer and enjoy the underwater sea life, there came some dangers that were not recognized and are potentially serious if one does not take diving serious. However, along with these new improvements came dangers for scuba divers, especially for beginners, that are caus... ... middle of paper ... ...omething goes wrong. It sounds pretty harsh right? Well this is because if a diver ascends too quickly to the top, they risk rupturing their lungs due to the water pressure as they go up. Well, another thing is if the person stays underwater but cannot fix the problem, then what happens? It causes an even greater problem. Either way they are risking themselves becoming injured. At any point in time during the dive, the person is susceptible to any form of danger. Some regions of the world are meant to be left alone and should not be disturbed by humans scuba diving. Sipadan Island, Malaysia could potentially become dangerous because it is a site where the Barracuda tornado occurs and it contains hammerhead sharks. This is a problem for scuba divers and one never knows what could possibly happen. Even if the diver is being extra cautious, injuries could still occur.
Underwater shark nets make us feel safer at the beach,but are we? That’s the question. Are we safe? There are lots of possibilities that the shark, with sharp like knife teeth, may outsmart us. Because of shark attacks we use nets, called shark nets. However, that doesn’t mean nets used in the past prevented shark attacks. These nets don’t only trap sharks they trap other sea creatures.
Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.
The First five weeks the student’s learn life saving, knot tying, underwater knot tying, basic first aid, and surf passages in small inflatable boats. Along with this is a 50-yard underwater swim, which must be completed and the students are often revived when they pass out. Also throughout out the whole six months of BUD/S (Basic Underwater Demolition School), the Seal Teams go through many torturous events and lessons. One of these being surf torture. This is where the entire class must wade into the surf zone to their waistline, then sit down with arms linked. Just to let you know the water in Coronado, California never gets above sixty-eight degrees during the summer and fifty-eight degrees during the winter. There the men with linked arms will sit there for hours at a time, soon the cold sucks out all of their body warmth and the whole class is shivering in unison as the waves crash over there heads.
Scuba diving itself can be challenging at times. Imagine having a difficult task, like welding, to perform at the same time as scuba diving. This is a task that can cost you your life if not done correctly and as safely as possible.
This force now can be used by the diver not only to go up, but to rotate and therefore perform various dives.
Divers will begin at the 80 ft wide entrance to this 100 ft deep, majestic sinkhole. Once divers reach 30 feet below the surface, there is the one and only fresh air bell in the Florida springs. Here divers can remove their masks, take a breath of fresh air and even have a quick chat with their diving buddy, if they so desire.
Swimming became a favored recreational activity in the US during the 1800’s. The occurrence of drownings intensified as water activity become more common. As many as 9,000 people drowned every year in the early 1900’s(History of Lifeguards). Once the businessmen who opened the pools and resorts realised there was an issue, they inserted lifelines. However, it became evident that these lifelines were insufficient because struggling swimmers weren’t able to clench onto them. For this reason, Duke Kahanamoku established the rescue board in Hawaii. Meanwhile in South Africa, Captain Harry Sheffield constructed the first rescue float. Although these worked for a few years, they were not the best option. A few communities stationed police officers at local water bodies to execute water rescues; However, this took away resources from law enforcement. This led to facilities hiring men and women who were trained particularly in water rescue. These individuals were labeled as lifeguards(History of Lifeguards). Now, when you attend a beach or a pool that is monitored by a USLA afflicted lifeguard, you have a 1 in 18 million chance of drowning(American Lifeguard).
I am adventurous. No I don't sky dive, wrestle crocodiles, or swim with sharks, but when asked by a group of friends to go cliff diving last summer, my best response was, “Sounds like fun!” I had never been afraid of heights yet have never experienced the thrill of cliff diving. All I could ask myself was, “What could go wrong?”

When diving around coral, be very careful of your flippers. They can accidentally smack into the coral and cause serious damage. Swim with care and keep track of your surroundings to ensure you 're snorkeling or diving responsibly.
8. Do NOT use air-filled swimming aids (such as "water wings") in place of life jackets or life preservers with children. Using air-filled swimming aids can give parents and children a false sense of security, which may increase the risk of drowning. These air-filled aids are toys and are not designed to be personal flotation devices (life jackets). Air-filled plastic tubes can deflate because they become punctured or unplugged.
Shark diving has come long way since its beginnings. It has led to new discoveries of creatures we still know so little about. Giving the common people a way to see a creature that’s feared, face to face, has opened up the minds of many. However, like many other things humans have become a part of, if man does not cherish and cautiously care for this gift we have we will ultimately lose and destroy it. Shark diving is an amazing way to open a person’s mind, but do not let your mind open ignorantly. Respect the shark and its surroundings and instances of injury or harm to you and the shark will not be a concern. Explore, takes risks and dive into a world that is wondrous, however, proceed with caution and take care to learn of the world you are entering.
Scuba gear is extremely important as the right equipment can mean the difference between enjoying your underwater world and being in fear of your life. Divers need to feel safe and at ease while exploring the best reefs and making the most of their underwater adventure.
Anytime you are out in the water, there is a chance something dangerous will happen. People can become stranded without a way to reach shore. Sadly, anytime you are in water, there is a risk of drowning, yet most drowning incidents occur in freshwater. It is smart to always be prepared and safe when near water.
Shark dives are done using a strong metal cage and it is not in the nature of sharks to attack the cage.
