Producing food

An intensive system of production capable of producing a lot of meat in small time has thus got hold to face growing consumers’ demand of meat. Farmers turn a raw material as cereals, available in great amounts at a low price, in meat which we eat. It’s an absolutely inefficient system as it uses much to produce little, infact, about 7 k of cereals and about 15 thousand litres of water are required to produce 1 k of beef meat! Apart from the consequences related to the overexploitation of resources, breeding farms have a substantial impact on the environment also with regards to the waste substances introduced in soil, water and atmosphere. Knowing the mechanisms of the meat production chain is important to discover what lies behind a beef steak, a ham slice or a chicken breast.
