How come Earth from a mere couple of 100,000 people, just in 4,000 BC (6,000 yrs ago), has grown to 6,000,000,000+ (6 billion in english money
) if population normally stays the same? Prediction for end of this century is 20 billion, I wonder if every person alive would still fit on the Isle of Wight then?
Nah, makes far more sense, like Nerfix says to have a small natural increase.
