More on the Logistic Equation

We shared our world population prediction. One clarification; the projected death count is not due to any reduction in birth rates. That reduction is already captured by the ap part of the equation that goes dp/dt = ap - bp^2. The population reduction we are talking about is measuring people who were born, but will die who otherwise would have lived.

The # we shared at around 2 billion in 60 years can seem staggering. But if you think about it, at least one million people died in Iraq last few years. And that was all about access to shared resources my friend, hence something that -bp^2 part of the equation measures.

One million here, one million there, soon we're talking billions. Unlikely?
