Final answer:
It is true that permits are required for wreck diving in some areas to protect underwater environments and historical sites. The Azores is one example where public awareness initiatives suggest a managed approach to SCUBA diving, potentially including a permit process.
Step-by-step explanation:
The statement that 'in some areas you need a permit to dive on wrecks' is true. SCUBA diving can have significant impacts on underwater environments, especially on historical wreck sites, which may be protected due to their cultural heritage value. Therefore, many jurisdictions require divers to obtain a permit to dive on wrecks to ensure the preservation of these sites. The permit process often involves providing information on the dive plan and sometimes participating in an instructional session concerning the specifics of the wreck and the environmental considerations associated with it.
For instance, in the Azores, efforts have been made to promote awareness about the marine environment, which might include informing divers about the considerations they must take into account when visiting local wreck sites. Activities like placing placards near dive centers and conducting public awareness sessions are part of the broader initiative to safeguard the area's marine heritage while allowing recreational activities like diving. These actions imply that there is a structured approach to managing how people interact with underwater wrecks and habitats, which likely includes a permit system.
