All the water on Earth.
supposedly that is ALL the water down to the water in your cells, water underground, etc. But I have seen other places that Science is not sure how much water is really underground so, grain of salt on that picture.
Can't be. The green forested/grassy places on the planet indicate that they left out a bunch of water.
Also, the moon makes it look like a sad (or sweaty) Death Star.
Looks like it is everything. Assuming biological water means water in living things. (chart at bottom of page). It says biological water accounts for 269 cubic miles. That is 0.003% of all fresh water, and 0.0001% of total water on the planet.

Oh. So the green parts must just be plant stains. Like, giant, giant grass stains, if the world was made up of knees.
Here is another interesting variation.
Liquid fresh water
How much of the total water is fresh water, which people and many other life forms need to survive? The blue sphere over Kentucky represents the world's liquid fresh water (groundwater, lakes, swamp water, and rivers). The volume comes to about 2,551,100 mi3 (10,633,450 km3), of which 99 percent is groundwater, much of which is not accessible to humans. The diameter of this sphere is about 169.5 miles (272.8 kilometers).
Water in lakes and rivers
Do you notice that "tiny" bubble over Atlanta, Georgia? That one represents fresh water in all the lakes and rivers on the planet, and most of the water people and life of earth need every day comes from these surface-water sources. The volume of this sphere is about 22,339 mi3 (93,113 km3). The diameter of this sphere is about 34.9 miles (56.2 kilometers). Yes, Lake Michigan looks way bigger than this sphere, but you have to try to imagine a bubble almost 35 miles high—whereas the average depth of Lake Michigan is less than 300 feet (91 meters).
All the water on Earth.
