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
Vertical farming is the practice of producing food and medicine in vertically stacked layers, vertically inclined surfaces and/or integrated in other structures (such as in a skyscraper, used warehouse, or shipping container). The modern ideas of vertical farming use indoor farming techniques and controlled-environment agriculture (CEA) technology, where all environmental factors can be controlled. These facilities utilize artificial control of light, environmental control (humidity, temperature, gases...) and fertigation. Some vertical farms use techniques similar to greenhouses, where natural sunlight can be augmented with artificial lighting and metal reflectors.
