Though desalinization is typically seen as an expensive option, Kent Gruetzmacher says there are some basic home techniques that can be used. W hile Earth is rightly dubbed “the blue planet” thanks to its vast oceans, this terminology falsely alludes to a supply of abundant, consumable water. In truth, only 2.5 per cent of the Earth’s water is fresh; that is, consumable by both humans and typical plant species. Moreover, a majority of this fresh water is contained in snow and ice—leaving only 0.3 per cent of Earth’s water available to be utilized. 76 grow cycle Through the past decade, as vast areas of the planet experienced water shortages, the global populace has recognized the need to for novel water sources. The most blatant option is the ocean; however, our vast reserves of seawater cannot be utilized for human consumption or crop irrigation without extensive desalinization treatment. Traditionally, the desalinizing of seawater as a source for drinking water has been viewed as unpractical. This is largely because, on a molecular level, the water and salt bonds within seawater are notoriously strong. As a res ձаѡͅѥɽ)ɕեɕ́՝չЁɝP)ѡЁЁٕ́䁍ѱ)ѕɥ͔Ѡ٥ɽх))Mѥȁեͥѥٔѕ)Ѽͅє݅ѕȁ)ɥɥѥѡɔɔ)ѥ
