Global water and air volume

... gathered into spheres and compared to the Earth.

The water sphere (blue) in this computer visualization measures 1390 kilometres across and has a volume of 1.4 billion cubic kilometres. This includes all the water in the oceans, seas, ice caps, lakes and rivers as well as ground water, and that in the atmosphere. The air sphere (pink) measures 1999 kilometres across and weighs 5140 trillion tonnes. As the atmosphere extends from Earth it becomes less dense. Half of the air lies within the first 5 kilometres of the atmosphere. The spheres show how finite water and air supplies are.

You've got a point there Koert, but that also depends on your definition of garbage :)
Now I would like to see the sphere that represents all human beings alive today.

What is your view on the coronavirus?


Koert van Mensvoort: The virus makes us aware of other lifeforms with other perspectives, desires and needs. It also teaches us that we are one humanity. These viral invaders don’t discriminate on the basis of nationality, race, income, social status, political or sexual preference. We are together and must work together to overcome. Stay safe.
