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.
Nobody knows exactly, but the estimate of 50 million is commonly used. Approximately 1,000,000 new divers are certified every year, but not all divers are certified. Nicaragua for example has over 50,000 lobster divers, very few of whom have formal training.
No. On average about 17 recreational scuba divers die each year. That is a low number (for 10,000,000 scuba divers worldwide), but I am pretty sure it is higher than the number of people who die bowling.
around a wonderful 80 degrees. My husband and I dive around there and the keys several times a year and will wear only a bathing suit and rash guard. If you intend to dive deeper than 50ft. I would wear atleast a 3 mil suit.
Most scuba diving photographers don't make a lot of money at it. I have been scuba diving all around the world and have been diving with lots of photographers and have a lot of friends that consider themselves to be underwater photographers. Every once in a while someone will have a photo published in a magazine but not very often. Some people put together books of their photographs and try to sell them. Most people take the photos for their own person use as there really isn't a good way to make money as a professional underwater photographer. Some people have made money going for a dive and taking photos of other divers and such but plan on eating a lot of Spam if you plan on living on the earnings of underwater photography. There are too many other people doing the same exact thing.
100,000
there is no real way to know, as no one keeps track of such a thing to the last person. however, when estimating with the numbers given by different dive agencys and putting them together you get close to 20 million divers. with a global population of 6.7 billion people on earth. Its about 0.3% of people dive. Now that's not to say that all these people dive actively. Some may have already died, stop diving, only dive once in 5 years, etc. So the the # is most likely less then estimated.
Urm - any country around the Red Sea: Egypt, Sudan, Israel, Djibouti, Eritrea, Saudi Arabia, Ethiopia, Yemen, Jordan, Somalia.Most people dive Egypt though. With all year round good weather (although it can get windy out to sea, especially Dec, Jan, Feb which can make the sea a bit choppy) and warm water, vibrant corals and lots of sealife, it's a great place to dive. Some places are very commercialized though (such as Sharm El Sheikh) and you can find yourself with 20-30 other divers on a dive site. The way to get away from the crowds is to go somewhere less dived or go on a liveaboard - where you spend the whole trip diving from a boat, but you are limited to evening activities and the people you are with.
If you have not dived for over a year or more, it is wise to get a refresher's course known as a Scuba Review to go over your skills.
Most important is Proper Training! A good dive shop won't even sell or rent you gear unless you can show proof of certification. Start with a 'Try Dive' often called Discover Scuba Diving to see if you like diving. Sadly we get fatalities every year from people who get hold of obsolete kit at yard sales and think it looks easy. The equipment is basically a Mask and fins, A Tank of air (Not OXYGEN) cleaned filtered and dried and typically pressurised to 3000PSI (That's right about 100 times more than a car tire), a depth compensated regulator to drop that to a safer pressure and a mouthpiece with a demand valve (Give air as you breath in shuts off as you breathe out). You also need a jacket or BCD to allow you to fine tune your buoyancy (Fish have a swim bladder to do the same job). Add a wetsuit or dry-suit and also a weight belt. The last piece of gear is a watch/timer/computer - to stay safe a diver needs to know how long and how deep their dive was - deeper dives are shorter. Kit needs checking and servicing regularly. Lastly your going to need a dive buddy - NEVER DIVE ALONE! Oh yes, some water to dive in, Ocean Lake or River, all offer rewarding diving but each has unique hazards (Plan the Dive - Dive the Plan).
