It Takes 20kg of Corn to Produce 1 Kg of Beef If a Person Only Ate Beef

Equally much equally 2bn tonnes of food are wasted every twelvemonth - equivalent to fifty% of all food produced - according to a study published today by the Institution of Mechanical Engineers (IME)
The IME estimate that thirty-50% (1.2-2bn tonnes) of all food produced is "lost before reaching a man stomach". Consumer affairs contributor Rebecca Smithers writes today:
The UK's Institution of Mechanical Engineers (IME) blames the "staggering" new figures in its analysis on unnecessarily strict sell-past dates, purchase-one-get-one costless and Western consumer need for cosmetically perfect food, along with "poor engineering science and agricultural practices", inadequate infrastructure and poor storage facilities.
Major supermarkets take also been blamed for nutrient waste matter past rejecting crops of edible fruit and vegetables which don't meet their exacting standards for their physical characteristics (such equally size and colour). Up to thirty% of the UK'southward vegetable crop is never harvested due to this type of practice the report claims.
The publication entitled 'Global food: waste not, want not' too aims to highlight the wastage of energy, land and water. Approximately 3.8tn cubic metres of h2o is used by humans annually with 70% beingness consumed past the global agronomics sector. The amount of h2o wasted globally in growing crops that never reach the consumer is estimated at 550bn cubic metres.
IME merits that water requirements to run into food demand in 2050 could reach between 10-13.5tn cubic metres per twelvemonth - nearly triple the current amount used annually past humans.
Meat production requires a much higher amount of h2o than vegetables. IME state that to produce 1kg of meat requires between 5,000 and 20,000 litres of water whereas to produce 1kg of wheat requires between 500 and 4,000 litres of h2o.
The table beneath shows typical values for the volume of water required to produce common foodstuffs. Chocolate tops the list with 17,196 litres of water demand to produce 1kg of the product. Beefiness, sheep and pork meat all crave high volumes of water for production also. Tea, beer and wine use the least co-ordinate to the list. Compared to the production of meat, vegetable foodstuffs require considerably less h2o - 1kg of potatoes for case uses 287 litres of water.
Expect at the table below to run into how much water is required to produce a selection of mutual foodstuffs. Also if yous want to see how much water nosotros consume indirectly through eating and drinking different foods, we have previously published a great interactive visualisation by Italian graphic blueprint specialist Angela Morelli.
