So "Maintain humanity under 500,000,000 in perpetual balance with nature"

Well if you take the 80% vaccinated goal and then compare that to current world population. The remaining 20% is just a little over 3x that "goal"

Sounds like a margin of error to me.... so if say 85% take it they have some wiggle room.

I suspect the % goal will creep up until they hit their 500 million ish goals...

Prion diseases for everyone!
