So, can we apply this equation to humans?

What do we know? Well we know that since the population
is exponentially growing, that lambda must be greater
than 1, for humans.

Let's see

So go ahead and plug in values of the various parameters to see what
combindation gives us lambda between 1.01 and 1.02, which is approximately
the growth rate of the world.

Also,
fire this up . What you do is when you have a solution, just cut
and paste the whole excel spread sheet into the clipboard, and then use
this application to publish to global view.

Okay now's lets think about the finite age equation
below. Why is this not applicable to human growth?

Time to make our own world population models:
