It takes about a gallon of water to grow a single almond. That does seem like a lot. Especially when compared to the water it takes to grow peas, sweet potatoes, or broccoli.
But virtually everyone that I have ever seen make a big deal about the water footprint in almonds are people who consume meat, dairy and eggs. Why does that matter? Well take a look
at the water footprint of these products. This makes it rather obvious, that the attack on almonds is not actually because of a genuine desire to educate others as to how to really reduce their water footprint, but rather is yet another thinly veiled attack on those who have managed to break their addiction to the, real enviromentally disastrous culprits: Meat, dairy and eggs.
For more on this subject, I encourage you to watch the fabulous documentary, Cowspiracy.
