Scuba divers require oxygen tanks because the partial pressure of oxygen dissolved in water is insufficient for human respiration. Unlike carbonated beverages, which release gas upon opening due to oversaturation, the oxygen in water remains at low concentrations under normal conditions. While submarines utilize advanced systems to extract oxygen from water, standard scuba diving relies on compressed air tanks to ensure an adequate supply of breathable oxygen at depth.
