I've long thought that one of the highest impact things scientists and engineers could be working on is developing a form of ivory that is indistinguishable from real thing to collapse the market. It seems like it should be feasible.
People will always figure out ways to distinguish one thing from another, if that's what they choose to do. It's not just a technical problem, it's a social one. We have to make it clear it is not okay to regard ivory hacked from the face of an elephant as better than a synthetic polymer. To regard diamonds scrabbled over the blood of Africans as better than their synthetic equivalents. To regard the flesh of torture…
The best thing to do would be to make natural ivory anything boorish and in bad taste.
Although there's a risk of exciting the morons: http://www.slate.com/articles/news_and_politics/politics/201...
