Bring back the concept of ZPG

In today's Guardian:

Leading water scientists have issued one of the sternest warnings yet about global food supplies, saying that the world's population may have to switch almost completely to a vegetarian diet over the next 40 years to avoid catastrophic shortages.

Agreed, but WHY AREN'T WE TALKING ABOUT POPULATION CONTROL, SCIENTISTS??? When I was a kid in the 60s a very important discussion began about a concept dubbed Zero Population Growth. It was a point of discussion even in my conformist baby-boom grade school classrooms. We don't talk about it anymore.

Just more evidence of how scientists have grown scared of going up against religious forces that are opposed to reproductive freedom including birth control.

I might add that when I was in that baby-boom-era grade school classroom and we were required to learn various dry facts about geography and demographics, one fact was this: "There are 3 billion people in the world." I am 55. To some people reading this that might be "old," but think of it as "less than one expected life span." The 3 billion has already turned into over 7 billion as of March 12, 2012.

The exponential breeding of humans is one of the most frightening factoids. Check this chart.

And since the vocal anti-science forces are breeding faster and indoctrinating their offspring ... if The Awake Ones are not outnumbered yet we will soon be, by far. What does that mean in this democracy? That our progeny will have to experience a horrible toxic world complete with massive disease and die-offs? ‎And will it by then be too late to "learn our lesson" and rectify the situation?

I personally stave off the depression from peering into this particular abyss by engaging in teaching the children. Teach the children (all children! this has nothing to do with "parenthood") and, more importantly, teach them to teach others.
