I try to be a positive person, though sometimes I wander into the negative as I may do a little in this thread.
Ever hear grandiose visions for the future of humanity and wonder if or when these things might come to pass? Colonizing Mars? Achievement of world peace? End of poverty and starvation?
I truly like the sound of the latter two, though the first is simply a 'meh' topic as far as I am concerned. Here, however, is why these are likely not achievable: The ties that bind, or commonality in each of us as humans.
With political and religious differences greatly dividing the masses of humanity on our planet, what makes one think we could set those aside long enough for the greater good, even if we had no other choice? Colonizing another planet like Mars? Ignoring the heavy hitters like lack of oxygen, water, and cold temperatures, humanity would most likely stumble over itself. Do you think for one minute that egos and temperamental personalities would not get in the way of such a grand undertaking? I'll leave it at that.
World peace? I always try to trust that peace treaties will work out, and then one side sees fit to ignore the honor of their word. Again, the ties that bind get in the way. Tunnel vision, or the belief that what one group believes is the only way, tends to slant most peace accords.
Ending poverty and starvation? For starters, it would require governments and corporations and billionaire investors to set aside their capitalist tendencies for the greater good of humanity. Short of a miraculous move of God, I do not see it happening. Another limiting factor on this one is the selfishness of many who are being helped. Rather than taking what they need, my guess is that many would take far more given the opportunity. In other words, greed sets in among those who have always had little or nothing. The ties that bind.
Just my 2 cents..
