I'm curious why someone would downvote this. Care to write a proper reply instead? I'm stating facts - why do you disagree?

I suspect it's being downvoted because the pixel resolution on the various species included have little to do with how healthy their populations are or are not. For example, it's simply impossible for large predators like tigers to exist by the billions. In short, the presentation is a pure play to emotions with little regard to any actual facts.

Thanks, but I disagree! Most of the pixelized animals number in the hundreds or thousands - horrifyingly low. What diversity and ‚culture‘ can exist within those numbers? There can be a ‚healthy‘ population of 1, but it's still extinction for the species.

I wish the downvoters would have the courage to speak up.

Fish are amazing, but do you really think they are SMART? In my experience, fish are incredibly stupid and wholly reliant on instinct. I suppose instincts can seem like intelligence sometimes, but if put into the wrong situation, fish will make the same mistake over and over and over again.

By that standard the monarch butterfly is stupid too. That said they are smart enough to follow only a portion of their full migratory route which takes 4 generations to complete. Squirrels remember where they bury their nuts. Octopuses can solve puzzles. So what about fish? Salmon remember where they were spawned before they head out to the ocean, and come back to the exact same pool to spawn before dying. https://b…
