Only 3% of the water on Earth is potable because the majority of water on Earth is saline water found in oceans. Additionally, some of the fresh water is locked in glaciers and ice caps, making it inaccessible for human consumption. Furthermore, water pollution and contamination degrade the quality of potable water sources.

What percentage of our planet is covered with water?
Not very much, really. If all the water on or in Earth were gathered together, it would be enough to make a "drop" about 680 miles in diameter. That sounds like a lot, but the Earth itself is about eight thousand miles in diameter... so even by volume, water is less than 0.1% of the Earth, and by mass it's even less (since most of the Earth is either rock or metal, both of which are heavier than an equivalent volume of water).
