How fast is the population rising?

Think of the biggest crowd you've ever been in, for example - 50,000 in a sports stadium. Just 6 hours from now there will be that many more people in the world. Another 50,000 in the following 6 hours, and so on and so on.

Every year, the population increases by the equivalent of the population of Canada..... times 2.

I'm sure a rocket scientist could answer this but does that make the planet heavier? Look out we're going to crash into the sun!!! R
