Population is a huge issue that is avoided or overlooked by most people
And healthy and happy are fleeting moments in mundane lives.
And healthcare is subject to the vagaries of wealth, power and genetic instructions..
How one evaluates the necessity of personhood, depends upon how one evaluates the purpose or intention of Universal progression.
And for sure, as single units most will always be hellbent on survival right here, right now with no real thought of the greater future.
The future is potentially a long time, and Planet Earth's resources are not unlimited.

Or do you think that everything is purposeless?
Well, as I see it, it's 50/50 chance or purpose.
