There are around 7 billion people on the planet right now. This fascinating graphic shows the world's relative population density.
To get an idea of the scope of what 7 billion people really means, take a minute and click over to 7BillionWorld (first this page, then this page to put it all into perspective).
With birth rates falling all over the world, the population is expected to plateau sometime in the next 50 years or so at around 10 billion people. That's a big, but manageable number. If we transition to a truly sustainable civilization, we can feed, clothe and house that many people.
