How could the world cope with providing enough food, clothe, shelter and fuel etc to keep the ever burgeoning population going?
We would end with young people being unable to have children, there would have to be no retirement age and we would need to work until.....when?
The current global warming crisis is caused, at least partly by our burgeoning world population. This is now not caused by excess births, but increased longevity.
Today it was in the news that the Japanes government is almost begging its young people to have children because so many of the population are old and getting even older.
Now, there are many economic and social reasons why this is happening in Japan, but put those aside. If you want to know what a world where old people make up a very large proportion of the population, and the young a much smaller proportion looks like and how it affects the economy then look at Japan.
Do I want to live forever - no. But I do not want to know when I will die eiher, at least not long-term. What I do want to do is live as healthy and active a life as I can until one day I do not wake up.
