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:
