Scuba diving involves using a self-contained underwater breathing apparatus (SCUBA) to breathe while diving underwater. ¹⁾

Scuba diving can be done in many different bodies of water, including oceans, lakes, and quarries. ²⁾

Scuba diving allows divers to explore a variety of marine environments, including coral reefs, shipwrecks, and caves. ³⁾

Scuba diving can be done for recreational purposes, such as sightseeing and photography, or for scientific or professional purposes, such as marine biology research or search and rescue operations. ⁴⁾

Scuba diving requires specialized training and equipment, including a diving mask, fins, a diving regulator, a buoyancy control device (BCD), and a diving cylinder containing compressed air. ⁵⁾

Divers must be physically fit and in good health to participate in scuba diving. ⁶⁾

Scuba diving can be dangerous if proper safety procedures are not followed. Divers should always dive with a buddy and adhere to safe diving practices. ⁷⁾

There are different levels of scuba diving certification, ranging from beginner to professional, based on the diver's experience and skill level. ⁸⁾

Scuba diving can be done in various depths, from shallow to very deep. The maximum depth that a diver can safely dive to depends on their training, experience, and the equipment they are using. ⁹⁾

Scuba diving exposes divers to the risk of decompression sickness, also known as “the bends,” which can occur if a diver ascends too quickly from a deep dive. ¹⁰⁾

Nitrogen narcosis, also known as “rapture of the deep,” is a condition that can occur when a diver descends to depths greater than 30 meters (100 feet) and becomes impaired by the effects of nitrogen in their breathing gas. ¹¹⁾

Some marine animals, such as jellyfish and certain species of fish, can be venomous or toxic, so divers should be aware of the risks and take precautions when interacting with marine life. ¹²⁾

Scuba diving can have a positive impact on the environment by promoting conservation and protecting marine ecosystems. ¹³⁾

Scuba diving can also be used for educational purposes, such as learning about marine life and the history of shipwrecks. ¹⁴⁾

There are many scuba diving destinations around the world, including popular destinations such as the Great Barrier Reef in Australia, the Red Sea in Egypt, and the Galapagos Islands in Ecuador. ¹⁵⁾
