Make love, not babies
The world's fate is in your hands, and in your pants
Mother Earth needs more people... like a fish needs a Ferrari
Population growth... ultimate Ponzi scheme
Be less fertile, Myrtle
Population growth... sexually transmitted
Global population... size matters
Less ovulation leads to population stabilization
Thinking more kids? Think again
Be fruitful, but... don't multiply
"Whatever your cause, it is a lost cause without population stabilization." Paul Ehrlich
