Farm-to-table
Despite the growth in the farm-to-table restaurants the movement has been met with some criticism. Critics argue the interest in knowing where your food comes from and ensuring it is locality sourced is just another food fad for millennials. Furthermore, the higher price point that many restaurants are forced to demand, given the higher costs of production and lower economies of scale, also make farm-to-table food less accessible for many people. The movement was originally closed tied to "tree-hugging elitists," who were able to afford farm-to-table food. Lastly, critics argue that the farm-to-table term is not fully understood by consumers. For example, foods advertised as farm-to-table are considered healthier regardless of actual nutritional content.
Vertical farming
Dickson Despommier is a professor of environmental health sciences and microbiology. He reopened the topic of VF in 1999 with graduate students in a medical ecology class. He speculated that a 30-floor farm on one city block could provide food for 50,000 people including vegetables, fruit, eggs and meat, explaining that hydroponic crops could be grown on upper floors; while the lower floors would be suited for chickens and fish that eat plant waste.
