While the initial reasoning is respectable, veganism is t without it's flaws, several plants are not ethically sourced and either cause a lot of pollution, destroy habitats to be grown, or are grown via slavery, or a combo of all 3. The real issue is the systems that are in place across the food industry, plant and animal based.

Almonds are a big one that I know of. The vast majority of the world's almonds are grown in California, a state that has been facing severe drought for years now (though maybe not so much this year), but somehow still finds hundreds of billions of gallons of water yearly to keep almond farms irrigated.

And eating almonds is one thing, but processing them into milk is an order of magnitude more wasteful. It takes about 400 almonds to make a half gallon of almond milk, and each one of those almonds requires a gallon of water to produce. So that's 400 gallons of water spent to produce a half gallon of almond milk. A single almond tree can make about 30 gallons of almond milk per harvest, so we're looking at 24,000 gallons of water consumed per tree, which yields a full shelf of Almond Breeze at a single grocery store.

And as farms keep expanding and conditions become drier and drier over time, it's going to destroy the ecosystems of the state. And all so that people can have a decent milk alternative to have with their morning coffee and cereal.

The majority of California's water usage is going to beef and dairy. They are large producers of animal feed which are heavy water users. Per liter, dairy milk requires 628.2 L of freshwater vs almond milk requiring 371.46 L of freshwater. And if you use something like oat milk instead that gets you to 48.24 L

One graph even has California's animal feed water usage so large it actually goes off the chart at 15.2 million acre-feet of water (it is distorted to make it fit as it notes). For some comparison, the blue water usage of animal feed is larger than all of almonds water usage of ~2 million acre-feet of water

This is true across the American West as a whole

Correspondingly, our hydrologic modelling reveals that cattle-feed irrigation is the leading driver of flow depletion in one-third of all western US sub-watersheds; cattle- feed irrigation accounts for an average of 75% of all consumptive use in these 369 sub-watersheds. During drought years (that is, the driest 10% of years), more than one-quarter of all rivers in the western US are depleted by more than 75% during summer months (Fig. 2 and Supplementary Fig. 2) and cattle-feed irrigation is the largest water use in more than half of these heavily depleted rivers

That being said, they still come out ahead in comparison to animal-based foods due to the fact that you need to grow massive amounts of feed crops to raise other creatures. It turns out that pretty much every environmental metric comes out ahead

Transitioning to plant-based diets (PBDs) has the potential to reduce diet-related land use by 76%, diet-related greenhouse gas emissions by 49%, eutrophication by 49%, and green and blue water use by 21% and 14%, respectively, whilst garnering substantial health co-benefits

Plant-based foods have a significantly smaller footprint on the environment than animal-based foods. Even the least sustainable vegetables and cereals cause less environmental harm than the lowest impact meat and dairy products [9].

In terms of workers, the meat industry is arguably worse on that front. It's one of the most dangerous industries anywhere for workers

US meat workers are already three times more likely to suffer serious injury than the average American worker, and pork and beef workers nearly seven times more likely to suffer repetitive strain injuries

Amputations happen on average twice a week, according to the data

And there's great risk of PTSD from the workers that you don't see for harvesting crops

There is evidence that slaughterhouse employment is associated with lower levels of psychological well-being. SHWs [slaughterhouse workers] have described suffering from trauma, intense shock, paranoia, anxiety, guilt and shame (Victor & Barnard, 2016), and stress (Kristensen, 1991). There was evidence of higher rates of depression (Emhan et al., 2012; Horton & Lipscomb, 2011; Hutz et al., 2013; Lander et al., 2016; Lipscomb et al., 2007), anxiety (Emhan et al., 2012; Hutz et al., 2013; Leibler et al., 2017), psychosis (Emhan et al., 2012), and feelings of lower self-worth at work (Baran et al., 2016). Of particular note was that the symptomatology appeared to vary by job role. Employees working directly with the animals (e.g., on the kill floor or handling the carcasses) were those who showed the highest prevalence rates of aggression, anxiety, and depression (Hutz et al., 2013; Richards et al., 2013). https://journals.sagepub.com/doi/10.1177/15248380211030243
