Overpopulation is killing the Earth.
Ecologically the Earth can only support 2 billion-doing no harm to the Earth. And we are heading toward 10 billion people.
Birth control is basically banned by all religions.
A quick, easy fix-not thought of by scientists-is for Humanity to switch totally to Oral Sex. (Mutual of course)-for 50 years...
This is necessary as many women get accidentally pregnant.
And just have sex, the other way, when wanting a child.
It is Simple, doesn't cost anything, and many men are in favor of the idea. And it will stop Global Warming in its tracks,by stabilizing,and eventually reducing the population.
Possibly, initially there will have to be free Oral Academies,taught by volunteers, to bring everyone up to speed, but the young will take to it by leaps and bounds.
And the Republicans can't ban Oral Sex...... Or can they?
