"When people get secure, and know that their children are going to outlive them,...............he size of their families goes down,"

perhaps..but not far enough down. Various cultures have a 'tradition' of large families coupled with reverance for ancestors that endures, secure and well-fed or not. There are many reasons for population increase, and many reasons for over fishing, but saying "The main cause of "overpopulation" is poverty and exploitation. And the main cause of overfishing and destruction of the environment is the greed and irresponsibility of rich countries,...." simply avoids the issue, even IF it were true.

Granted, more care could be taken, resources guarded, the poorer nations could be given a fairer share, etc...but I know, (and YOU know, if you are honest), that given the opportunity, the poorer nations would be greedy and exploitative also. It is human nature we are fighting, not the USA or Brazil or Japan or Russia, though each of those nations has current practices that need reining in. People, given a chance, will take more than they should, and it is never easy to see how to curb this.

My point is, if EVERYONE on earth and ALL national entities were to share fairly and be as environmentally reasonable as they can figure out how, this will only delay the problem!. You cannot increase the population, even at a reduced rate, forever. The Earth will NOT support 857 Billion people, no matter how responsible and careful they are.

The thing is, **Nature** does not care...if we don't figure it out, corrections will be made thru the laws of biology and physics, and it won't be pretty!

There are plenty of social and political changes wich could and should be made regarding 'richer' and 'poorer' nations, etc., but please do not deceive yourself that "all will be well" then....If it pleases you to simply have everyone suffer equally, so be it. I'd rather look for solution that makes fewer humans equally happy and prosperous....and I can't think of a easy, fair way to achieve that....My comment about requiring a permit to remove a contraceptive implant was only slightly facetious....if there were a 'fair' way to do that, I'd vote for it tomorrow....

....I have a son who is 18...I dread thinking what HE will face at 60.
