What I find most frustrating is that the wars we are usually fighting are over the remaining land, water, and energy resources left. Yet, fighting these wars costs us unimaginable amounts of these ever depleting resources as well.
It's as if, after seeing a possible end to humanity in the distant future, our leaders have decided to RACE to that end with as much violence as possible.
There's no excuse for this. Hard times do not call for desperate measures -- that's a lazy and unimaginative view. Hard times demand cooperation.
