It’s why you gotta burn ivory. When something is a luxury item for the wealthy rules don’t really matter you have to destroy the market.
If we ever fully restore the keys, we’d opt for not-ivory.
I have a more than one hundred years old Austrian piano (made shortly before the start of the First WW), and it still works fine.
yes, i'm sure this is true for 100% of people buying fancy pianos, and "proof of sustainable harvest" isn't at all a loophole that gets used to sustain an illegal ivory trade.
Not saying this exonerates the practice or anything --just that rich folk in Hong Kong/mainland CN aren’t the only ones propping the market.
