Life is cheap!

[Urendi Maleldil]

I think the reproduction rate is fine the way it is, but a slight increase would be better. The thing we need for populations to not be so 'cheap' is to have greater consequences for icing a planet's population. If, for example, we had a Mars colony, and the Martian government decided to dump large ammounts of people into deep space, I'm sure the population of Earth, unless they really hated the Martians for some reason, would become very unhappy with the government of Mars.
