It is fairly obvious hydroponic gardening is poised to become a primary source of agriculture in the future. Hydroponic grown vegetation is believed to have preceded soil grown vegetation in our oceans dating back to the creation of the earth. In fact, the Egyptians, Inca Indian tribes, the Aztecs, and the ancient Babylonians all practiced hydroponic gardening. Today we can see hydroponic gardening re-merging in third world nations as governments, communities, and villages scramble in an effort to provide nutritional food supplies in arid lands.
Many people today live in areas of the world that have been incapable of producing sufficient food crops or are nearly impossible to irrigate. While some arable land remains underused because it is under the control of hostile governments or is currently too inaccessible for farming. Improving this infrastructure would mean battling a swarm of logistical, sociological and religious challenges.
Hydroponic gardening gives everyone, regardless of location, the ability to grow more than enough food to meet their needs in the solace of their home for pennies with marginal effort. This prevents improving or rebuilding a flawed infrastructure and affords individuals and families without access to fresh food the ability grow fresh, healthy fruits and vegetable year round without aid or expenditure from respective governments.
Because hydroponic gardening systems are able to produce more food using fewer resources (primarily space, water, and money), hydroponic gardening has become the obvious solution with respect to ending world hunger. Less developed areas in the world may not have the complex hydroponic gardening systems NASA builds, but they make use of the materials at hand….and with hydroponic gardening anything is possible.
Here’s a great article on how some organizations are developing innovative hydroponic gardening structures. http://www.bbc.com/future/story/20130603-city-farms-to-feed-a-hungry-world
