In the first bar, notice how only 2.5% of all Earth's water is freshwater, which is what life needs to survive.
The middle bar shows the breakdown on that 2.5% which is freshwater. Almost all of it is locked up in ice and in the ground. Only a bit more than 1.2% of all freshwater (which was only 2.5% of all water) is surface water, which serves most of life's needs.
The right side bar shows the breakdown of only the surface freshwater, which was only about 1.2% of all freshwater. Most of surface freshwater is locked up in ice, and another 20.9% is in lakes. Notice the 0.49% of surface freshwater that is in rivers. Sounds like a tiny amount, but rivers are where humans get a large portion of their water from.
In fact, look at the globe to the right. There is a tiny 3rd bubble hovering over Georgia, USA. That is the size of a ball of water with all the freshwater in lakes and rivers, yet the water in that bubble has the huge responsibility of serving most of humans' and animals' water needs.
