What is a potential impact of diver traffic on wreck sites?

Diver traffic can significantly impact wreck sites, primarily by increasing the risk of damage to both the wreck itself and the surrounding marine ecosystem. When divers explore wrecks, they may inadvertently disturb the structure by touching, kicking up sediment, or displacing artifacts. This can lead to physical damage, such as the breaking off of pieces or destabilizing the wreck structure, which may have remained intact for years.

Additionally, the surrounding marine ecosystem can suffer due to increased sedimentation and disruption of habitats. Marine life relies on wreck sites for shelter and as a source of food, and frequent diver traffic may disrupt these vital ecosystems. The cumulative effects of many divers can alter the natural state of these environments, potentially leading to a decline in biodiversity and habitat health over time.

On the other hand, the other options do not accurately reflect the realities associated with diver traffic. Improved conditions for marine life and enhanced structural integrity of the wreck are not typical outcomes of increased diver activity, as such activity tends to have the opposite effect. Less visibility may happen, but primarily due to sediment being stirred up instead of being a primary impact of diver traffic itself.
