The pictures you have done are like specially done for travel magazine , I like the most the last one because of such impressive unique sunset, you are lucky to be able to experience it life. But of course underwater pictures with such exotic underwater life is also something that we have to think about when we leave out litter and garbage just laying there where we were having little stop. Especially how that underwater animals suffer from that. Of course, as it is said "Out of sight out of Mind" but it is not really disappeared. So your post and pictures are reminder to keep this pearl of nature and do everything to safe it for future :)
