The accelerated growth of the human population and urbanization of it, poses a great poblem food already this feeling in some parts of the planet, from the year 2000, 2800 million people live in modern cities, this figure doubles the number of people living in the countryside.

The production of food has also declined taking techniques that employ high technology and toxic fertilizers to be able to increase the production of food.

The big problem is that the big cities are not producing all food need, are absolutely dependent on the resources that derive from the environment in which they find themselves, so as depleting resources cities increasingly must go away to get the vital resources on which they depend.

The hydroponic foods are grown using a special technique that does not require the use of fertilizers or industrial chemicals, instead used something called substrate which is not more than half inherte in which holding cultivation.

The crop is fed directly by a mixture of nutrients that normally contains land for the normal growth of the plant.

The hidrophonia is not a new technique, has been used by humans since Babylonian because of the dryness or shortage of fertile soil.

Using automated control means to maintain adequate levels of nutrients in plants or using manual means of control can lead to a stable production of food per family nucleus, this would be the principle of self-sufficiency food in the cities, where each family of the city produces a stable quantity of food and could use these for their healthy diet besides trade surplus with other families or in a common market of food in the cities, this would Lighten the burden of food depending of the camp and would create self-producers food cities have not only  industrial processing centers. 

Nuestro hogar es la naturaleza

En la lucha eterna del ser humano por controlar el poderio de la naturaleza hemos olvidado por completo que tambien hacemos parte de ella, talamos los bosques para hacer nuevas casas sin pensar en el daño que esto produce a los suelos, suelos que nesesitamos para cultivar nuestros alimentos y poder sobrevivir, por eso me he planteado la pregunta de que tanto el ser humano considera la nauraleza su hogar, o mas bien como un medio hostil el cual es nesesario destruirlo sin importar nuestro futuro proximo o el de nuestros hijos.

Particularmente en mi estado, Zulia en Venezuela se presenta el tema del carbon como un tema dificil, resulta seriamente inesesario la explotacion de este recurso dañino para la atmosfera contando con medios mucho mas limpios como el gas para la produccion de energia.

Los entes gubernamentales que promueven el uso del carbon responden al pais afirmando que el carbon es para la exportacion, pero?  , acaso no vivimos en el mismo mundo y lo que se quema en china o europa no afecta igualmente la naturaleza de nuestro pais; simplemente la explotacion del carbon obedece a intereses particulares, alizanzas economicas con ciertos grupos de la poblacion para mantener una nefasta busqueda de riqueza en la sierra del perija, destruyendo la flora y fauna autoctona.

Este no es mas de un ejemplo de como los seres humanos consideramos la naturaleza no como un hogar, sino mas bien como un lugar hostil del cual sacar riqueza. Mientras nuestra conciencia individual no cambie y dejemos de vernos como una region, estado o nacion, para comenzar a considerarnos parte de un todo, una especie, no podremos mas que permanecer en silencio mientras se aproxima nuestra extincion.
