Q: Do people really struggle to find clean drinking water?

A: Many places in South America and Africa struggle to find clean drinking water because of too high levels of salt and sewer water. Also 783 MILLION people suffer from not clean water.

Salt

Prediction: 70

Fresh

Prediction:  30

Air 26%
Ground 19%
Surface 25%
Ice 30%

• Earth's water is 97.24% Salt water
• Earth's water is 2.86% Fresh water
• The air is 0.001% water
• The surface is 0.01% water
• The ground is 0.61% water
• The ice is 2.14% water
  

This.. was.. very... surprising, I was very off. My prediction was that there was 70% salt water in the world, and I was off by 27.24%. Then I thought that there was 30% Freshwater in the world and I was off by 27.14%. Now I have knowledge about this unlike before because I had NO clue. It actually makes sense now because a hear on the news a lot about people suffering from not enough clean water to drink. We are fortunate enough to have Lake Michigan near us so we can get lots of clean, fresh, and purified water.
