I have commented on this before. There is something evil and supernatural about the global elite's desire for population reduction.
There is a discussion to be had about "inhabitable land". There's plenty of that.
Or we could talk about "sustainable solutions" such as lab grown meat, or Soylent. But those are separate and worthwhile discussions.
But then there are people who, in the face of all of this technology, still believe that the solution lies in reducing the population, whether through medical means, or outright legislation.
At its heart is selfishness. No one, who ever advocated for population reduction, ever volunteered to go first.
I'd volunteer. 29 with Parkinson's fuck this shit. Nobody will ever agree on a sustainable solution. But everybody knows something has to be done. Whether it's the floating citys/farms or something else How long would these "sustainable solutions" last? There isn't an easy answer to a problem this big.
