Summarize Argument
The author concludes that a new synthetic ivory, which is the first substitute to make high-quality piano keys, won’t do much to stop the killing of elephants for their ivory. This is because piano makers have never been major consumers of ivory.
Notable Assumptions
The author assumes that the synthetic ivory won't replace real ivory for purposes other than piano-making. Otherwise, there's no reason to think that its impact is dependent on piano makers alone.
