It takes 15000L of water to make 1kg of meat

“The fairly widespread figure of 15,000 liters of water needed to produce one kilogram of meat is one of the arguments to be qualified. Indeed, the value of 15,000 liters of water was obtained for the calculation of the “water footprint” which includes blue water (consumed by animals and crop irrigation); gray water (depollution and recycling of livestock effluents, that is to say organic waste) and green water (rainwater). However, the “water footprint” method is designed for industrial sites. It does not take into account life cycles, water that returns to the land, plants … It is not directly applicable to agriculture.

In reality, INRA estimates that 95% of this water footprint corresponds to rainwater, taken from the soil and consumed by plants. This quantity returns to the water cycle, and it would be consumed even if there was no breeding. Thus, INRA advances the figure of 550 and 700 liters of water to produce 1 kg of beef. In comparison, on average, a flush corresponds to 12 liters, a shower to 60 liters and a laundry to 100 liters. “
