I think law will be passed that will prescribe lead content as an "for now" start to a solution. Government will state that no bullet may have more than a 50 % lead content and manufacturers will figure around the law with offerings.

Is there enough will and financial, political backing to force any change over and above the token gestures we have seen in regard to banning lead ?

Banning lead?  Good luck in THIS third world country.
I am quite happily shooting a my own wheelweight cast lead bullets in my 9mmP and 38 Spl.  Will have to buy hunting bullets for the rifle though.
