vertical farming, hypothetical
AGRICULTURE, GLOBAL VILLAGE
The as-yet theoretical use of stacked vertical spaces-e.g., those found in tall buildings–to grow food.
Pros Increased crops yields by controlling the environment, eliminating floods, droughts; eliminate use of pesticides and other chemicals; land conservation and return land to natural state and halt mass extinction of species; reduced spoilage of crops as they are adjacent to consumers, reduced transportation costs; increased access to healthy food–reducing obesity, diabetes, heart disease, certain cancers; energy–e.g., methane, production by normal agricultural waste products
Cons High cost of building dedicated spaces; relative lack of sunlight would require supplementary light; greater energy consumption; need for supplemental CO2 to enhance plant growth
