What? 15 billion people on what? Most people in Africa eat much worse than
the rest of the world. If what you say is true (and I doubt it), then it
is a sad statement about humanity in general regarding our ability to feed
ourselves.


Unfortunately it is a sad statement about humanity. Witness Ethopia, a
country once known as Africa's breadbasket. It was a next exporter of grain
before the Communists came to power. Then it became a net importer as much
of the population starved to death.

I have heard about this decline. But I have never actually seen an example

We shall see. As of yet I see the earth increase in population like a

Then learn to tell time.
