A continuously growing population will increasingly threaten to create scarcity and destroy life providing resources.
Population is the big multiplier that causes all of the four previously mentioned common problems (craving, world vision and culture, scarcity and matter control) to create devastating global impacts.
We now need 9 planets to support the existing 6.6 billion people to live like the average US citizen.
By 2040 the population will reach max population of 9 billion people.
Opportunity, education and global awareness reduce population growth more than simply offering birth control.
