How many wars were started over natural resources? How many people must suffer? Water is rapidly becoming one of our planet’s most scarce and precious resources. Our generation must seriously address the growing global water crisis. To achieve a healthy balance between human need and available natural resource drain, we must introduce a reliable, secure, and economically efficient development of new water. The initiative Hungry for Salt aims to alleviate heightened demands for fresh water supplies by using Earth’s oceans to irrigate crops, a subtle change in farming that will feed the world.
Oceans cover nearly 71% of the Earth’s surface. Of this, 97% is saltwater and 3% is fresh water. Of the 3%, less than 1% is available for human use, and this percentage is shrinking rapidly.
An experiment using lima beans and lettuce seeds tested varying levels of water salinity levels. Both seed types were chosen for their nutritional benefit. Lima beans contain an excellent source of protein, which is useful as a meat replacement, and are rich in irons, calcium and vitamins. Additionally, lettuce is an excellent source of Vitamins A and C and calcium. The results confirmed that although lima bean and lettuce seeds cannot grow in ocean salinity levels, they are able to adapt to a moderate salinity level. Hence, the world oceans can be used to grow food producing plants when the salinity is reduced to acceptable levels.
Governments and industry focus on increasing food production, with little regard for natural resources. The unequal distribution of food and conflict over control of the world’s dwindling natural resources creates a major political and social challenge to governments, likely to reach crisis status as climate change advances causing more droughts, world population expands, and water demands increase. Continuing with existing trends would mean the Earth’s economically advantaged and disadvantaged people dividing further apart. It would leave us facing a world nobody could inhabit.
Two current methods of processing seawater are distillation and reverse osmosis processes; however these require large amounts of costly electricity. To eliminate the need for expensive electricity and create remarkable cost savings and environmental advantages for users everywhere, Hungry for Salt will employ Forward Osmosis desalination technology, known as Engineered Osmosis (EO)*. The EO process produces drinking water at less than half the cost of existing desalination systems. This is achieved by eliminating the need for high-pressures used in reverse osmosis methods, thus reducing the electricity and fuel demands by more than 90%. The effect is a decrease in the finances of salt water desalination that will finally bring the price of delivering water from our oceans below the cost of surface water.
My specific plan is to: one, further identify seeds, such as lima bean and lettuce seeds, that can grow in acceptable levels of salt water; two, further develop efficient engineered osmosis processes; three, target potential growing areas; four, start to pilot reduced salt water based farms.
