Urban and Suburban Horticulture

Farming on all arable land may be in our future

Diminished – image pitiably.com

As arid lands increase and arable lands are developed humans may discover the waste water of today can be used for numerous gardens. Agriculture and horticulture in cities , towns and suburbs may be needed to feed us. Not a new idea but perhaps a time to restate its potential and importance.

. . . the world may have a highly efficient rechargeable lithium battery that is very safe, no more: exploding toys, burning cell phones or fires on board air craft.  What is of even greater importance? Electric cars and large drones too.

“Replacing conventional lighting sources with LEDs with an efficiency of 200 lumens per watt would decrease the global electricity consumed for lighting by more than half. That reduction is equal to the electricity created by 230 typical 500-megawatt coal plants and would reduce greenhouse gas emissions by 200 million tons.”
