Question 1

Why is there such limited availability of water?

Answer 1

Out of all the water on Earth, only 2.5% is Freshwater. Of that 2.5% only 1% of it is surface freshwater (as glaciers hold 79% and groundwater containing the remaining 20%).

Therefore only 0.3% of Freshwater is readily available in lakes, streams, rivers etc.
