Hello; It is good to know that others have made the same choice as my first wife and I did. There is little reward beyond the satisfaction of feeling that a right thing has been done. I have faced the opposing arguments and negative comments many times over the decades. Some have put down the choice to remain childless just as some posts on this thread have.
Nearly fifty years ago much was still untested and yet to come about. There has been an enormus amount of study and research done since then. I based my choice to remain childless only in part on the projections about future world population. (By the way the world population has a bit more than doubled since then if I have my numbers right. This is no longer speculation.) Other reasons that influenced the choice were more focused on the ongoing environmental issues and in particular the attitude of the majority of the prople I encountered. It became apparent that then, as now, there were a significant amount of people unwilling to even consider the real and potential problems facing us. It seemed very likely that any children I might bring into the world would live long enough to have to endure the negative consequences that were comming and many of which have in fact already arrived. I also knew that I would care deeply for those children. With the information and the understanding I had at the time it was still a difficult choice as there was then still a reasonable chance for people to make wiser choices. As it has turned out there have been fewer regrets than I had feared.
I think that I have come to a small understanding of why so many people are so strongly against the things I stand for. If they begin to accept and understand the import of the environmental degradation that has gone on and continues, then they will have to face what that implies for their own lives and the lives of their children, grandchildren and others they may love.
I feel sure that you have faced the same sort of negative reactions over your choice to be childless. Some on this forum are a great deal more unplesant in the wording of their comments. I suppose it is because they are shielded by the nature of anonymous forum as no one has said such things directly to me. The children that I did not have are not competing for resources with them or their family, that would seem to at least be neutral to them. Why my choice to be childless has fostered such rancor is often a bit of a puzzle.
