"Whatever your cause, it is a lost cause without population control."
That means muzzling the religious wackos against family planning, spaying, birth control, and ABORTION.
Too many people is a major (but not the only) cause of wars. Wars have been and will escalate over resources -- land, water, fishing grounds, etc.
But, not to worry. The ability to wage war with high tech will disappear as the insatiable appetite for resources such as oil and rare minerals increases with increasing population and strips easy access to them.
Or, we could just drown in our own sh*t. It COSTS money and RESOURCES to handle waste.
BTW, the reason millions of people here, Haiti, wherever your favorite wogland are starving is that too many people are dropping litters of spawn with no thought of how they might raise and feed them. Boo, effing, hoo.
