Wind turbines

I'll counter your trees with my humans. Would you agree that skinning children to make drums would be "needlessly cruel"? The creator might have thought that it was necessary for whatever reason, but neither the children nor any sane observer would agree. It's fine to disagree on what's moral and what's not, and it's up to the invidual to decide for themselves. I think killing turtles for vanity project is cruel, especially since you have all those trees that just deserve to be carved up for being so tall. I believe there is some common ground most interested parties can agree on. And if not, then the situation is probably quite complicated and you should rethink making those drums.

If it hadn't used mother of pearl and tortoiseshell, which weren't particularly rare at the time, they would have used things like rosewood, ebony, and ivory. So either way, precious materials were going to be used.

At least they are being used in the service of Art, and Music, instead of something vain, or selfish, like jewelry or beauty accessories. If these materials are going to be harvested anyway, using them to create a fine musical instrument, which can then be used to create beautiful music for a century, or possibly longer, is a worthy use of those precious natural materials.

I do think that there are layers to the corruption in play here. It'd be plenty evil even if it sounded good and looked bad, since cruelty and stuff. Pianos are expensive, and were even more back in 1853, so having and playing one was a hobby limited to elites, which had to exploit the work of the poor to afford it and the rest of their luxurious lifestyle, which makes it worse again. Due to it being one of the possible symbols of the class status, it's very ownership rather than a function became a priority, which then made it a piece of visual art to be admired rather than the tool to create such art, which degenerated the meaning of such expense even further. The author most likely wasn't thinking about the cruelty, about the class or about the demeaning the art, or maybe they were and it was the point. Either way, the result is something beautiful that shouldn't have ever existed, and the "incredible poetic" characteristic that I mentioned earlier (maybe a bit of an overstatement) referred in part to this contradiction.
