A city is supplied by water from local wells. The city discharges its treated wastewater into the ocean. The city uses 25,000 liters of water per person per year. Precipitation falls in the amount of 25,000 liters per person per year. Is the city using its water supply in a sustainable manner?

A)yes
B)no

B)no

Explanation:

Sustainable use of water means use of water to fulfil various human needs for water without having any negative impact on the environment.

The sustainable use of water allows a minimum of 20 to 50 litres of daily water per person to fulfil their water needs, that means 600 litres maximum per person per year but in the given situation the city uses 25,000 litres of water per person per year.

This shows that people in the city are not using water sustainably which is causing a fall in precipitation.

Hence, the correct answer is "No".
