Scuba diving is an underwater activity that allows individuals to explore the ocean while using a self-contained underwater breathing apparatus, or scuba. This equipment provides divers with a supply of air, enabling them to breathe while submerged at various depths. Divers typically undergo training to learn safety procedures, equipment usage, and underwater navigation. Popular locations for scuba diving include coral reefs, shipwrecks, and marine parks, where divers can observe diverse marine life and ecosystems. Proper certification is often required to ensure safety and competence in the water.
