Size of Life

If you’re interested to read something on that topic I highly recommend the essay "That's About the Size of It" by Isaac Asimov (in his book "View from a Height").

He argues that human perception of animal size is skewed because humans use themselves as a benchmark.

He takes a logarithmic approach to illustrate where humans actually fit within the overall scale of the animal kingdom. We are way larger than we think we are!

We are megafauna predators! We’ve wiped them almost all out, which makes it less obvious, but that’s our ecological niche.
