Did you know that July 11 is World Population Day? It's a very important day that aims to raise awareness of global population issues and how our world is changing as more and more people try to live together, find a space of their own and share resources.
Do you know how many people there are on the Earth? You might be surprised with how many there are...
Oh, you want to know how much 7.7 billion actually is? Well, it's a lot. Like A LOT! In fact, it's so much that it's actually a little hard to imagine. But since you asked, we're totally up for the challenge! Here we go.
An Olympic-sized swimming pool can hold around 2,500,000 — or 2.5 million — litres of water. So, 7.7 billion jelly beans would fill...
No problem, right? Seconds are super fast. Well, they are until you put that many of them together! You 'll be waiting for a really long time actually.
Hold up a piece of paper. See how thin it is? It's only 0.1 millimetres thick. Well, if you stacked 7.7 billion sheets of that stuff, you'd have a stack 770 kilometres high!
Uh oh! OK, I'm going to go hang out in the jelly bean pools. If anyone asks — that giant paper mess totally wasn't my fault.
