Which phrase encapsulates 'Leave nothing but bubbles' in diving ethics?

The phrase "Leave nothing but bubbles" emphasizes a commitment to preserving the underwater environment and ensuring that divers do not disturb or take anything from the dive site. The correct encapsulation of this spirit is "Take nothing but photographs." This phrase captures the idea that divers should only take visual memories of their experience, allowing them to enjoy and share the beauty of the underwater world without causing damage or removing items from their habitat.

Taking only photographs promotes responsible diving practices, encourages conservation of marine ecosystems, and fosters respect for the underwater environment. It highlights the importance of leaving dive sites undisturbed for future divers and for the health of marine life.

The other choices, while they might seem related, do not align as closely with the values conveyed by the original phrase. For instance, the notion of taking nothing but memories, while meaningful, lacks the active commitment to preserving the environment that the correct phrase embodies. Likewise, leaving behind gear or taking seashells contradicts the principles of responsible diving, as they could harm the ecosystem.
