Question
Answer in your own words.
Why is there a shortage of water even though it occupies about 71% of the earth’s surface?
Solution
Although water occupies about 71% of the earth's surface, all of it is not potable water. Most of the water is available in the form of seas and oceans, which are salty in nature. This saline water has its limitations and cannot be used for many purposes. Around 2.7% of water exists in the frozen state or as groundwater, which is inaccessible. Only 0.3% of water is available as potable water, which is fit for human consumption.
