Scuba diving is a sport that has been practiced for centuries. Scuba stands for Self Containment Underwater Breathing Apparatus, where people dive underwater with a gas cylinder to breathe with the assistance of masks, fins, a breathing regulator, a flotation device and pressure gauges to explore the environment submarine. In the early 19th century, new improvements were invented to help divers stay underwater longer and have a smoother dive. But there is still doubt whether it is still safe to go scuba diving or not due to the dangers that come with it. And there are some areas of the world that divers should be aware of. Although technological improvements have made scuba diving safer by allowing humans to remain submerged for longer periods of time, scuba diving should not be practiced, especially in particular regions of the world. Most of the dangers that come with scuba diving are caused by extreme water pressures. The very first scuba dives performed were in search of jewels and were very short until a way to breathe underwater for longer periods of time was invented. In order for divers to stay under water longer, they used a hollow barrel. Research shows that later "helmets were made of metal to withstand even greater water pressure and divers went deeper" (MarineBio.org 1). These technological improvements have given divers a smoother dive, allowing them to enjoy more time submerged in the ocean's depths. In addition to the ability for divers to stay underwater longer and enjoy underwater marine life, there have come some dangers that have gone unrecognized and are potentially serious if you don't take diving seriously. However, along with these new improvements have also come dangers for divers, especially beginners, this is due to the cause... half of the paper... something goes wrong. Sounds pretty harsh, right? Well, that's because if a diver ascends too quickly towards the top, they risk rupturing their lungs from the pressure of the water as they ascend. Well, another thing is if the person stays under water but can't solve the problem, what happens? It causes an even bigger problem. In any case they risk getting hurt. At any 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 diving humans. Sipadan Island, Malaysia, could potentially become dangerous because it is a Barracuda tornado site and contains hammerhead sharks. This is a problem for divers and you never know what could happen. Even if the diver is extra cautious, injury could still occur.
