A water diver, commonly referred to as a scuba diver, explores underwater environments for various purposes including recreation, scientific research, and commercial activities. Equipped with a self-contained underwater breathing apparatus (scuba), divers can breathe underwater and move freely. Recreational diving offers a unique way to experience marine life and underwater landscapes, while professional divers may engage in tasks like underwater welding, marine biology research, or ship maintenance. Divers must undergo rigorous training to ensure safety, learning skills such as buoyancy control, navigation, and emergency procedures. Advanced certifications allow for deeper dives and specialized activities like cave or wreck diving. The sport promotes environmental awareness and conservation, highlighting the importance of protecting aquatic ecosystems.
