Which Is Least Likely To Be A Reservoir For Fresh Water?

Answer:

Fresh water is least expected to be found in the Oceans among all the options.

Seas and oceans occupy a major part of the World Geographical Network with more than 71% and consist of salt water hence cannot be used to supply water. Due to its concentration, salt water found in oceans cannot be drunk raw by human beings without first being treated in some way. Although desalination is a proven technology, it requires a lot of energy and is costly hence, it is out of the question to rely on oceans as a large source of freshwater. Moreover, oceans are full of pollution that makes getting safe and pure water even harder or almost impossible. For instance, the Pacific Ocean, which is the largest ocean in the world, occupies approximately region of 63 million square miles; nevertheless, it cannot be utilized directly in the sense of freshwater source because of its salinity and pollution. To the same logic, seas and saline lakes, which are also mentioned in the document, cannot be considered to be freshwater supplies either. This type of lake consists of a very large amount of water, but said water is unfit for drinking due to its high mineral content, For instance, the Great Salt Lake is located in Utah, USA. Several recommendations touching on are as follows: The document stresses that research into freshwater sources such as groundwater, surface water and rainwater harvesting should be carried out as a way of meeting human needs in water.
