Thank you. I thought they were good questions too
You inquired
why should one seek to extend their life to delay the inevitable?
Give me a coupla' thousand years to reflect upon that, and perhaps a satisfactory answer may then occur to me
Not for nothing, but overpopulation has a simple solution. Humans must stop breeding like rabbits. Yes, its really that simple.
Read more, and understand more:
Total Fertility Rate vs.
Birth Rate
Most animal populations remain relatively stable in numbers when there is a natural and superior predator species that keeps it in balanced check. As we sit upon the top of that food chain, only our own species can manage its own numbers to retain that sustainable balance (wars, and disease, and other natural disasters notwithstanding).
Lets just say that a sizable portion of our species is more concerned with unbridled procreation than, well heck, anything else.
There are some trees alive today that have been around in excess of 4000 years
is a tree a more practical part of an earthly existence than a sentient and consciously self-aware human being?
Hmmmm?
