7 billion and counting

"Earth will become home to 7 billion people later this year, and most of the planet's growth will affect the developing countries the most, straining those regions' limited resources, a Harvard University professor said Thursday."

When I was in 6th grade, it was 2½ billion. Since I am now over 70 and in good health, I am now wondering if I will see the really serious symptoms of over population...(even beyond over fishing, water rationing, frantic emigration, and ethnic violence...etc.)

Oh...also, when I was a kid, they showed movies explaining how technology and automation would give us lots of 'free time' and 30 hr. workweeks. They failed to note that meant only for those who still HAD jobs.
