I thought of adding this article too, because it looks like there are Some Hopeful News About the Future of the World’s Corals.
Much has been learned about heat-resistant corals in the last decade. Village by village and beach by beach, reef restoration is progressing.
Maybe so, maybe no. It's not predetermined.
It's what we do now that will shape the future. I mean, we the people. We cannot rely on governments or corporations to do the right thing without us forcing them to. By now, we know this.
So, I believe that conversations about solutions are more fruitful than deterministic statements, no matter how highly upvoted these statements are.
