It doesn’t matter if Miami is a port or not the fact is there is coral thriving there and we should respect that.Because Miami isn't the destination. It is a port. A departure. Also it isn't about Disney although they are one of the two in question. Agree or not Miami is a hub for that line of business due to location. My guess is before Covid they had looked at their schedules, ships, bookings past, present, and future and came to the conclusion they needed another.
Again, it is the conversation that should take place as to what it means by removing, relocating, or anything else related to the project. Doesn't matter if it is this 1,000 feet of reef or the Hanauma Bay State Park reopening ever again after bouncing back from no visitors. Devils advocate is about taking the emotion out of it and looking at the bigger picture of what possibilities promote to the top when said discussions take place.
Maybe they have enough ports. Maybe they move else where. Maybe they look at trying to relocate. Not my line of work but as hobbyists who take in a lot of corals and fish via trade from various environments around the world with little to no care this save the reef seems a bit, well, boggling.
tl; dr - the theme here is not should we or not but rather taking a look at the request and see what options are available to solve the problem for all invested parties. Common ground. Like a marriage or partnership.
The bigger picture should never be human oriented but rather Nature oriented.
