Life by the Numbers | It's Okay to be Smart | PBS Digital Studios

Now this was very interesting and educational to watch.  There are a lot of human beings on this planet and PBS compares us to the rest of the earth.








There are now more than 7 billion human beings on Earth, and that got me wondering: How successful are we compared to other species? I take a look at out how our numbers stack up to some other domains of life. It turns out that biomass, or what things weigh, can be more important than how many of something there are. Find out how our numbers stack up against everything from bugs to bacteria, and get ready for some mind-blowing numbers!
