Which action is discouraged to minimize environmental impact during diving?

Feeding fish while diving is discouraged as it can significantly disrupt the natural behaviors of marine life. When divers feed fish, they can inadvertently create dependency on human-provided food sources, leading to changes in feeding patterns and altering the natural ecosystem. This practice can encourage aggressive behavior among fish as they become accustomed to being fed by humans, which may also attract larger predators or disrupt local wildlife interactions.

Furthermore, feeding can lead to an imbalance in the marine environment, causing overpopulation of certain species that might outcompete others for resources. By minimizing interactions that can alter natural behavior and relationships within ecosystems, divers help preserve the delicate balance of marine habitats, making this a vital consideration for environmentally conscious diving practices.
