What would motivate a person to be a cheerleader for population growth?
Being a bidness leader hoping for more customers hence more dollars in his pocket?
Being a politician hoping to increase his base and fund his Ponzi schemes?
Being a religious leader hoping to achieve world dominance via having his group out-reproduce all others?
Being a military hungry for more cannon fodder?
Being an egomaniac that thinks more copies of themselves blesses the world?
Being a crazy egg-layer that won't be "fulfilled" until she fertilizes as many of her dumb eggs as possible?
Being a simpleton that buys into the rhetoric from ^?
There must be others too...
Oh yeah, being in the food aid industry that has found the line of work too lucrative to ever want to end.
P.S. Or being a freak that wants a "reality" tv show based on reproductive largess.
