I was a long time fan of the
Club of Rome and it associated book the
Limits to Growth.
My viewpoint has changed over the years, but they (the CoR and the book) were the reason that I never wanted children. A great deal has happened over the years since the publishing of that book (and I really don't recall most of the book very well). Many of it's worst fears have failed to come to pass. Others have only been put off.
From being an old time hippie in the '60s, believing in many of the things espoused by other MR members, to my current outlook on life, I've seen the best of people and the worst of governments.
Beware of any solution that has the best interests of humanity as it's goal.
Lets face it, a reduction of the population will have to occur. Whether by decree or "plague", it
will happen.
We're living in an artificial world buoyed up by our ingenuity. Lack of medical, and agricultural knowable helped, in the past, to keep the population down. Wars helped to keep the population down also. There have been many other, smaller, reasons too.
Those who say that homosexuality is hardwired into their genes may be unwittingly pointing to a viable solution. I say this only partially tongue in cheek. A homosexual bio-engineered virus could be a workable solution to a population problem. Details to be worked out later. Any writers that want to start up a story based on that premise are totally free to use it.
Yes, there are many problems that we'll find solutions to. The world isn't going to end tomorrow. But I think that we have far more to fear from our "solutions" than we do from global warming.
MY only fear is that I'll live as long as some of the others in my family tree have lived.
