Comparing the land and water use of cows versus almonds is ridiculous for many many reasons.
If you've been to a cattle ranch (not a CAFO) and to an almond farm, you'll know exactly what I mean. Almond land use is land use: it's barren of all life besides almond trees. Ranch land in comparison is typically semi-arable, has living things other than cows on it, and while cows sequester water (like all other living animals), the notion that they use more water because rainfall catchment on ranch land isn't absolute is a collossal error in thinking.
Also note that calories per 200ml aren't shown, which is really where the math breaks down. Whole milk has 160 calories per 8oz glass.
Unsweetened almond milk has 40 per 8oz glass.
Soy milk, the most calorie dense of out all of them, which is totally reliant upon monoculture, pesticides, and artificial fertilizers only has 80.
So, you know, multiply the vegan options, or divide the cow milk appropriately.
There are fantastic naturally vegan foods (including whole almonds and whole soybeans). Investigate those before indulging in ersatz environmental sleights-of-hand.
There are also tenable reasons to be vegan (or at the very least to reduce animal product consumption). Arguing that lifestyle identity products are sustainable isn't one of them.
Final positive note: oats and oatmilk are fantastic. You can make it yourself, then cook the sludge for porridge. Oats grow on marginal semi-arable soil and their husks are useful. Eat more oats.
