Literally, scuba diving means using diving underwater using Self Contained Underwater Breathing Apparatus.Conventional scuba equipment usually consists of a cylinder of compressed air (worn on the diver's back), and a "regulator" which converts the air from being highly compressed and delivers it to the diver at a breathable pressure.Scuba equipement also technically include rebreathers, which are a much more sophisticated form of diving equipment, whereby the air which the diver breathes is constantly recycled through a carbon dioxide scrubbing system.Scuba diving is now a popular recreational holiday activity, with over 10 million certified scuba divers worldwide.

Being able to dump it easily if required in an emergency.

I would decide not to scuba dive -- or climb a mountain, or parachute from an airplane -- if I felt the potential risks and costs outweighed the potential benefits. In the case of scuba diving, such risks include SCUBA apparatus failure, the Bends, nitrogen narcosis, shark attack, or being stranded in mid-sea following a group diving expedition. There would also be the cost of training, certification, and equipment (whether renting or purchasing). How I weigh these against the benefits of diving (the likelihood of adventure, potential for learning, bragging rights among my peer group, etc.) is a judgment call that only I can make for me, and only you would be able to make for yourself.
Being certified, shouldn't you know this valuable information? But the short answer is a loud and resounding "No!"
Sometimes. There is always a risk when you go in the water and going underwater is a greater risk. That is why proper training and being careful about how and where you dive are important. Scuba diving is no more dangerous than skiing in my opinion.
why? or how? you have many elements that make scuba diving safe. being aware of your limitations such as amount of time you can dive, the speed of descending and ascending in the water, using the buddy system where you have someone with you under water, a gauge to monitor your air level, you learn certain hand signals to communicate to your buddy in order to understand each other in case your out of air or there is a problem. also knowing weather conditions such as water currents that could drift you from your boat or land. the biggest part of being safe is being aware of your surroundings and well aware of the training material when you get certified.
