What is the water footprint of the foods we normally bring to our tables? This is a very important data, which we never find reported on the label. The water footprint indicates the volume of water needed to make a product at an agricultural and industrial level, taking into account both the water actually used and the water polluted in the various production processes.

What is thewater footprint of the foods that we normally bring to our tables? This is a very important data, which we never find reported on the label. The water footprint indicates the volume of water needed to make a product at an industrial level, taking into account both the water actually used and the water polluted in the various production processes.
It is not surprising that at the top of the ranking they find the beef and pig meat, a fact that makes us reflect once again on the strong environmental impact of farms. In second place, immediately after pork, here is the green tea. When we drink a cup of tea, we will now be aware that thousands of liters of water are needed to make the product.
THEdrinking water it becomes a real blue gold, on which the food industry draws more and more to ensure continuous production. Just think of developing countries, where access to drinking water is difficult, if not almost absent, to understand that the time has come for ask the food sector to contain consumption and waste.
Here is the complete standings of the foods that consume more water according to the data of Water Footprint Network.

The highest water footprint is that of tea, which requires 8.860 liters of water to produce 1 kilo. And for each sachet that contains about 3 grams of leaflets, about 30 liters of water are consumed, according to data transmitted by Water Footprint Network.
Pig meat
For the production of 1 kilo of pork are used well 6000 liters of water.
Rice
To produce 1 kilo of rice you need 2500 liters of water.
Sugar cane
To produce 1 kilo of brown sugar are needed 1800 liters of water.
Bread
To produce 1 kilo of bread it takes 1600 liters of water.
Orzo
To get 1 kilo of barley you need 1420 liters of water.
Mele
To produce a single apple it takes 125 liters of water, which rises to 1140 liters of water per pack for apple juice.
Latte
It seems incredible, but to produce only 1 liter of milk you need 1000 liters of water.
Wine
For wine, the water footprint is 610 liters of water per kilo, so a single glass consumes well 110 liters of water.
