  1. Yes, it can recover. The process I've pointed to is real, but even the areas covered with macroalgae can become available again, for example if there is a healthy population of herbivorous animals. Here is one of the recent studies on this interplay: Macroalgal cover on coral reefs: Spatial and environmental predictors, and decadal trends in the Great Barrier Reef | PLOS ONE. They have found that, My knowledge of these processes is supported by 25 years of direct and close observations of the corals in the Bonaire Marine Park. But also limited to it.
  2. It is not at odds with what you've read. Bleached coral is not dead. It is just the same living coral but without the symbiotic algae in it. The coral itself is like miniature jelly. It is colorless. The colors are those of the symbiotic algae. The coral without the symbiotic algae is alive for a couple of months. Bleached. Then it starts dying. Corals expel the algae naturally, when the water gets warm, and get the algae back when the water temperature goes down. It is when the water temperature stays warm for too long, which happens recently with the climate change, the bleaching becomes bad for corals. The sunscreen effect, very old news. The signs here remind divers and snorkelers not to use sunscreen - or use special kinds only - for at least 10 years now.
  3. Moreover, the government does not have to be a theocracy or even to be religious. Examples are USSR, NK, etc.
  4. 1. There are crucial differences in light and water movement with depth which are disadvantageous for shallow water corals. 2. As soon as original coral population dies, the surfaces become covered with algae which prevents settling of new coral larvae.
  5. Yes. This is exactly what will happen. In some virtual reality.
  6. The 2-halfday "Coral restoration" course for divers is very popular here for several years already. The baby corals are planted manually by happy divers and subsequently happily grow. It is inexpensive and fun. These corals will be killed eventually by the climate change just like others.
  7. The idea of not using fire alarms in churches, mosques, and temples, because it was not in the tradition of earlier Muslims, Christians, and Jews, so it is more normal and better without the fire alarms.
  8. Past failures tell you what not to do. Do things which you have never done in the past.
  9. My practical suggestion is to realize that these are empty words. You already have left the past if you wanted or not. It is gone and cannot be changed. You move towards the future if you want or not. It is inevitable. Even a dead rock moves towards the future. Forget about slogans and consider the issues at hand.

    Thank you. I have the same wish but can't do more than this as there is no overseas voting in Israeli elections.

    Is MAGA a synonym of "Americans"? Who are "the Israelis"? I have an Israeli passport and many Israeli friends and relatives. We are "Israelis," and we have a very good understanding. Thousands of recent demonstrators against the reforms and the government have it, too.
  12. A full video. Several of them. I can stop interfere and just tell you, that this answer is wrong and think of another one. Or I can suggest a mental experiment, like this: It could suggest the answer without more videos perhaps.
  13. I just add information as if you make an experiment and get the result. My only evidence is a detailed explanation of what is happening, but that would ruin the puzzle.
  14. I see. Yes, it is not what I thought it is. Sorry for that. Now I understand your answer. It is correct! +1
  15. Yes. It is not so. It does not make sense. IMO, it was dead on arrival.
  16. It is heavy headed.
  17. @exchemist, your answer is correct. +1.

    I assumed you did. I wanted to mention them for other readers.
