SCIENCE!

This is an interesting article from the WSJ. It explains how a census of Emperor Penguins was conducted using satellites. Through the study, scientists determined that there are many, many more of that penguin species than originally supposed.

It's a great example of how technology is making species health easier to track. It is also a great example of the limitations on our ability to observe the world around us. We often hear about the number of undiscovered species that are out there, or the populations of various common and endangered species. We must remember that much of this is (educated) speculation, and should be treated as such.

I am a great believer in science, and a realist with regard to its limitations.
