What is one reason why wrecks are often considered delicate environments?

Wrecks are often considered delicate environments primarily because they can contain fragile artifacts and ecosystems. The historical and cultural significance of wrecks makes their preservation crucial, as they can boast a variety of important items that are sensitive to handling and environmental changes. Additionally, the underwater ecosystem that develops around wrecks often includes unique marine life, which can be disrupted by human activity or changes in water conditions. This delicate balance makes it vital for divers and researchers to approach these sites with care, ensuring that both the artifacts and the ecosystems are protected.

In contrast, while being located in deep waters, visited by predators, or experiencing strong currents may also present challenges, these factors do not inherently reflect the fragility of the wreck itself or the surrounding environment as related to the preservation of artifacts and ecological health.
