      Lots! Mostly small ones.

      There are billions and billions of flies and other creepy crawlies. In fact, some people say that they rule the world, not us!

      If you mean in terms of population, then Adam is right, thousands of other species are more abundant than people. There are only 7 billion humans on the planet but there are nearly a *hundred trillion* bacteria in and on *every* human body!

      But it’s not just tiny bugs – there are about 24 billion sheep on the planet – that’s nearly 3.5 sheep per person!
