On May 5, 2009, some began taking population control into their own hands:

"New York meeting of billionaires Bill Gates, Warren Buffett, David Rockefeller, Eli Broad, George Soros, Ted Turner, Oprah, Michael Bloomberg...discussed in the top-secret meeting included....slowing the global population growth."(See Wall Street Jounal Story)

I hear Oprah is back on the eatin' wagon...I can just hear her now, "mmmmmm....Soylent Green."

1. The pollution of the environment may eventually affect the birth rate. Estrogen mimic chemicals have an impact on the sexing of trout to aligators. So the problem may be self correcting.

2. In terms of biological evolution when single cells got together and produced multicelluar organisms, there developed a way to control the type and number of cells in a this more complicated organism. Uncontrolled growth is generally seen as cancer. In that sense the human race may be acting as a cancer in gaia. Since we as a species are aware of this, there seems to be the possibility that a self regulation of the numbers of our species on earth may be possible. It would seem that an arrangement for people to control the number of offspring should enable them to become members of a society where everyone is cared for. This goes to the control of the borders preventing uncontrolled immigration. The operation of the social insects could give some insight on how this might be organized, as per "Brave New World" by A. Huxley. Freedom to breed seems to be something not possible in the new world order.

What is not mentioned a lot here:

...and in the above piece are FEEDBACK MECHANISMS?

These are not the kind that are forced or written into law...they occur as rational consequences related to human endeavours and expectations.

In other words...humans do their stuff...and the "real world" reacts and forces humans onto a non-planned path.

My personal opinion is that while some humans might see what's here and on the way....and try to change to avoid a precarious future...I doubt that they will manage to actually do things all that much differently...thus God or Gaia...or just plain reality is gonna bite.

As far as overpopulation...when we still have several major religions promoting overpopulation...apparently in a contest to see who will "win"...we should be prepared to meet the FEEDBACK MECHANISMS or the 3 horsemen?

Not to mention nations competing for remaining resources...and polluting like there is no tomorrow to build economies to sell more stuff to more and more people.

I can only laugh.
