Podcast: Soy, Almond, Oat Milks: Are They Udder Bull?
By: Science Vs.
In terms of environmental impact, dairy milk is the worst compared to all other types.
Globally, dairy cows graze an area the size of Brazil.
On average, it takes 9 times more land to produce dairy milk compare to the others.
Almond milk requires a lot of water, and most of Americans almonds are produced in California where there’s already a lot of water pressure. It can take 4 times as much water as the other non-dairy types.
Rice milk production emits the most greenhouse gasses in the form of methane. Flooded rice paddies are filled with methane-creating bacteria. Also fertilizer runoff can be a big problem with rice.
Soy and oat milk both require more land than the other non-dairy types. Also a lot of Soy milk is grown near or in the Amazon.
There is no clear winner among the four non-dairy types. But they’re all very low impact compared to dairy.
If everyone in the world switched from dairy to soy, it would save half a billion hectares of land, a billion tons of greenhouse gases, and the same amount of water as if everyone in the world stopped having showers or baths for a year.
