Thank you for the question, colleague, and, by the way, I add my voice to your comments with respect to the tragic passing of the SAR tech. These are remarkable women and men who do unbelievable things, so I think it was appropriate to acknowledge that sad news.
On the question of whether they apply to everyone and all concerned, it would depend on how they are drafted. There are a number of ways and a number of measures that can collectively constitute a marine protected area.
I'm not trying to weasel out of your question. They could, and in some cases may, apply to everyone; however, in a number of other cases, based on scientific evidence and complete transparency in terms of what that means, there perhaps are some people who would be less impacted or who would see a marine protected area apply to them differently
