What would be best; is a gut-level emotional demand for an urgent bureaucratic response - which entails getting people to 'demand' an irreversible power-grab by an all-powerful centralised authority.
Exactly as is currently happening with 'Climate Emergency' - get some precocious school girl (with pigtails to make her seem younger); and have her make a passionate appeal to the 'grown-ups' to Save the planet NOW (no questions asked).
And Save the Planet by monitoring and regulating a universally-produced, necessary for life, natural metabolite.
And Save the Planet by means that you know for sure will not work; thus requiring ever more concentration of power, and ever more intrusive management of everything: omni-surveillance and micro-control.
Against this manipulation; what defence do the Western masses have?
None so far.
Because they have no stronger motivation than their own (short term) gratifications... And these are precisely what is being manipulated.
Only a religion - or some such cohesive and powerful positive motivation held with long-term and religious conviction (if such a thing exists) - can protect the masses against such manipulation.
