So I was just partaking in the China thread and have come to a few conclusions about human society and our future and wish to partake in some serious discussion on the matter.
[ My thoughts]
I believe that you could justify killing a monumental amount of people in an effort to preserve and/or benefit humanity/society because you are reducing the strain that mankind places upon nature and the overall economic structure of any given society. (though I am not advocating it here)
I believe this because humanity is destined to lead itself to extinction as it shares many traits with a flesh eating parasite and will continue to consume and breed beyond all logical reasoning until their is nothing left for them to consume but each other.
Eventually it will get to the point that killing others will be a requirement for self preservation, at least if something isn't done to bring the birth/death ratios in line with each other which are only getting further apart due to the advancements in medical treatment and our ability to increase our natural lifespans.
In short consider that within the next two hundred years the entire world will be as densely populated as India is now and then ask yourself when that happens where you will grow your crops raise your livestock and build your dwellings.
If it came to that point today would you hesitate to cut down your fellow man as if they were mere blades of grass to survive or will you be one who gets cut down when the survival of the fittest mentality is forced into play because nature can no longer sustain the population.
Like it or not that is the direction humanity is heading in due to having an overzealous sense of morality that is valued over critical thinking and logic.
[My solution] (based on China's failed solution)
their needs to be laws in place that limit the total number of offspring people can have to 2 because it takes 2 people to make a child thus any less than 2 children would half the population every generation however the population will still dwindle due to the fact not everyone is going to have kids (this law could be adjusted every 10 years based on the needs of the society)
I am also for requiring everyone to pay for their own medical treatments considering once they are no longer productive members of society they are burdens to society and it is not an economically sound plan to extend the duration of a life no matter how badly you want to do it.
Now I seek your input especially if you have a more ethical way of population control that is still Logically sound.
