Highly toxic mercury is used as an amalgamation agent by many miners, legal and illegal. All too often, illicit miners dump it into streams or rivers, where it becomes a stubbornly toxic agent working its way up the food chain, eventually reaching humans. High levels of mercury have been linked to health problems, including birth defects and neurological disorders such as Minimata disease.

From what I have read here, it sounds like those making money selling mercury and cyanide legally or otherwise are never going to yield to the HGP or any other alternative unless the demand for mercury and cyanide is no longer there. Starting small and growing has worked in other industries. Is there a way for Haber to do this?
