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

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!
