Agricultural decline in most countries is linked to the fresh water shortage, drought and, as a result, the loss of fertile land. A chronic lack of fresh water for irrigation could jeopardise the entire industry, so an efficient and cost-effective way to desalinate sea water is needed to give a chance to restore crops around the world. Until now, most attempts at seawater desalination have turned out to be too expensive and energy-intensive.
By 2040, a new, efficient way to desalinate sea water has became available: it uses nano-tech graphene. This is a modified carbon layer one atom thick, which became the basis of the membrane that allows only water molecules to pass through and has the requisite strength for continued use. This method of desalination makes it possible to produce fresh water on the massive scale necessary for farming and at a low cost.
It will be a real salvation for Central Africa and Latin America, a hope for survival in a prolonged drought. Also, it will give the opportunity for countries with rich marine resources such as Cyprus, Greece, New Zealand, Australia, Madagascar, India, South-East Asia to develop agriculture more effectively.
