Finally something to fight the food shortage problem!! Conceptualized by Dickson Despommier, a professor of public health at Columbia University, this is sure to be both environmentally friendly and economically profitable. Added to this the dream of preserving a little of the country in the city is a utopian one which now will help fight global warming too. The professor believes that only by allowing significant portions of the Earth’s farmland to return to forest do we have a real chance of stabilizing climate and weather patterns. Merely reducing energy consumption would not suffice.

Allowing forests to regrow where crops are now cultivated, he believes, would reduce carbon dioxide in the atmosphere. Besides, with the world’s population expected to increase to 3 billion by 2050 and almost 80 per cent of farming land in use, the idea has never been more relevant. The best way very rationally Despommier argues, is to change the way we farm.

Dr. Despommier estimates that it would cost $20 million to $30 million to make a prototype of a vertical farm, but hundreds of millions to build one of the 30-story towers that he suggests could feed 50,000 people. “I’m viewed as kind of an outlier because it’s kind of a crazy idea,” said he. The revolutionary scientist envisions blocks of vertical farms in the world’s biggest cities, each structure 30 stories high that could potentially be as productive as 588 acres of land and grow up to 12 million lettuces a year.

Currently he is in discussions with potential investors to build the first prototype. For Dr. Despommier, the high-rise version is on the horizon. “It’s very idealistic and ivory tower and all of that,” he said. “But there’s a real desire to make this happen.”
