Food crops can be directly consumed. Cash crops should not be processed before use. Food crops are grown for consumption. Cash crops are grown for sale.
Today, cash crops are grown and traded around the world. In many cases, these crops are grown as a food source to feed humans or livestock animals. Some cash crops, like cotton, produce clothing. Many others are used to produce prescription or recreational drugs, including opium, coca, and marijuana crops.
Cash crops are grown for direct sale in the market, rather than for family consumption or to feed livestock. Coffee, cocoa, tea, sugarcane, cotton, and spices are some examples of cash crops. Food crops such as rice, wheat, and corn are also grown as cash crops to meet the global food demand.
