I agree, it seem impossible to force humans to do anything, so a change of perspective must come first. I don´t think 7 billions or 10 is a problem we could easily feed 10 billion, if we ate like the standard citizen of India. That would also save a lot of water, but again something must wake humanity up.

There might be no other way, only seeing first hand the consequences of our actions will be enough, but those consequences won´t come knocking on the door prior to a catastrophe, since it is as you say, the consequences will be catastrophical : /

I will stay optimistic, and do my best to inform fellow humans, of the time bomb we have set in motion, and hope that it won´t have to go boom :) Let´s go 10 billion humans in peace and prosperity :))

The war purse of America / EU / China, could clean water to humanity by it self. Bad focus here, and yes, we sadly acts as viruses atm
