Food crisis stems from four main causes:

• The production of biofuels takes over land for growing corn and sugar cane.
• The increasing consumption of meat in the developed countries, as well as in China and India, requires an increased output of feed (seven or eight kilos of high-quality feed is needed per each kilo of meat) such as corn and soybeans.
• Deregulating foreign food trade (towards the end of the 20th century) meant the destabilization of production, reserves, and the consumption of food in most countries.
• The monopolization of food production is practiced by American companies, with fourcorporations dominating most farming business and bringing local farmers to bankruptcies; small farms produce healthy and tasty produce whereas those giants offer unhealthy and tasteless food.
