New York City has thousands of empty rooftops; flat, unused, full sun, vacant land. It’s enough space to feed 15 million people. Check out this video about state of the art urban farming techniques.
"Keeping agriculture sustainable increasingly means keeping it local. Besides the environmental benefit of reducing reliance on fossil-fuel guzzling transportation, eating local food is a more seasonal and often healthier experience. With concern about food security growing, it might turn out to be safer, too. The folks in charge of the Science Barge, a new urban farming experiment in New York, are bringing local food production closer than ever. In this video Vanessa Rae learns about the floating greenhouse facility, which is designed as a demonstration of how urban space, especially rooftop space in big cities like New York, can be used to efficiently produce food. Self-powered by solar panels, wind turbines, and a biodiesel generator, the Science Barge uses state of the art computer technology and an agricultural technique called hydroponics to grow fruits and veggies using much less water and space than field farming. Watch out, city slickers. Farm country is coming to your neighborhood."

I really love to read articles which are very informative and the topics are based or concerned with the current issues in our society. I admire these writers in sharing their views and or opinions that can enlighten the mind of the readers. Great job!
Proper Hydroponic growing systems:
DO NOT USE
• Insecticides or harmful fertilizers to pollute the air and soil/ground water
USE
• Systems that are designed to use what nature gives us
• Nutrients that do not pollute soil and air and systems are designed to be energy efficient
• Atmospheric water generators to control humidity and replenish the systems, keeps the water usage to a minimum and are designed to be energy efficient
• Deep water is dug in soil, fed by gravity producing a very low electrical usage
• Bio degradable packaging
• Composting of waste products which is turned to tea or compost
• LED’s for supplemental lighting, which are rated higher than all other light sources in a greenhouse environment, with less than half the wattage of the traditional lightning systems
