Over a certain percentage, I bite into chocolate and it just sucks all the moisture out of my mouth and is just terrible bitterness. I think 86% was the last one I tried, but even 50% is getting to be too bitter for me. I was always super sensitive to bitter compounds as a kid, though, so that may make sense. I do actually like black coffee of some beans/roasts, but it doesn’t have nearly as much bitterness.
That’s not how that actually works. Damming has huge impacts on downstream, now much drier, ecosystems. Even if there were a way to “open a gate for fish”, that wouldn’t solve the problem that their habitat is now gone. This is among reasons people have fought for dam removal. This also ignores the flooding of the environment that becomes the reservoir.
