Over 90% of the world’s supply of freshwater is located in Antarctica. However, 68.7% of the Earth’s fresh water supply is trapped in glaciers.

The human body is 60% water, but the brain is made up of 70% water. That’s a lot of liquid sloshing around up there!
Water is without a doubt the most essential resource we have here on Earth. Humans, animals, and the Earth itself are made up almost entirely of water, so it stands to reason that H2O is pretty important! Indeed, water does countless amazing things like regulate the Earth’s temperature and hydrate all living things.
