Oh I forgot to mention water! Actually almonds can grow almost without any water at all, this is how we do it in Sicily, but certain varieties will yield 2x product if you use water. Hence in CA usually water is used, but with systems to use as little as possible.
It makes me irrationally angry how often things could be done sustainably but of course aren’t because there’s no strong enough incentive to care about negative externalities.
And they transport almond milk in cartons all over that is worse. The packaging and the space it takes for transport and the protocol for liquid transporting and the carbon foot print of pasteurization and so much more are entirely unnecessary because almond milk is so easy to make from a powder/almond meal.
But consumers are used to pouring it from a carton. Consumer education is so essential.
