Some of my best friends are Vegans. I think they went off meat went they watched the Australian film "Babe."
They are vegans. Mind you, they have not forced their veganism on their two children. Growing up, the kids had parties at McDonalds whilst the parents were vegans. It strained our relationship when preparing menus.
The New York Post has an opinion piece by Kyle Smith under the title:
If you’ve ever suspected nothing is more annoying than prissy, sanctimonious vegans, it turns out you have company: Nature wants to punch them in the face, too.As is often the case with virtue-signaling lifestyles, number-crunching doesn’t quite justify the supposed benefits of granola-crunching. “When applied to an entire global population, the vegan diet wastes available land that could otherwise feed more people,” concluded news site Quartz in a review of a scientific study published in the journal Elementa that compares the sustainability of various eating patterns.
UhOH! From News site Quartz???

Being vegan isn’t as good for humanity as you think
Using biophysical simulation models to compare 10 eating patterns,researchers found that eating fewer animal products will increase the number of people that can be supported by existing farmland. But as it turns out, eliminating animal products altogether isn’t the best way to maximize sustainable land use. Their work was published in Elementa, a journal on the science of the anthropocene.The researchers considered the vegan diet, two vegetarian diets (one that includes dairy, the other dairy and eggs), four omnivorous diets (with varying degrees of vegetarian influence), one low in fats and sugars, and one akin to the modern American dietary pattern.
OK - Here we go. Here is the root of the report - a peer reviewed paper published inBased on their models, the vegan diet would feed fewer people than two of the vegetarian and two of the four omnivorous diets studied. The bottom line: Going cold turkey on animal-based products may not actually be the most sustainable long choice for humanity in the long term.
Well, should I tell my friends? Should I tell them that they, because of their veganism, are depleting World Food Supplies?
Well, Back to Quartz:
Abstract (bold added)Strategies for environmental sustainability and global food security must account for dietary change. Using a biophysical simulation model we calculated human carrying capacity under ten diet scenarios. The scenarios included two reference diets based on actual consumption and eight “Healthy Diet” scenarios that complied with nutritional recommendations but varied in the level of meat content. We considered the U.S. agricultural land base and accounted for losses, processing conversions, livestock feed needs, suitability of land for crops or grazing, and land productivity. Annual per capita land requirements ranged from 0.13 to 1.08 ha person year across the ten diet scenarios. Carrying capacity varied from 402 to 807 million persons; 1.3 to 2.6 times the 2010 U.S. population. Carrying capacity was generally higher for scenarios with less meat and highest for the lacto-vegetarian diet. However, the carrying capacity of the vegan diet was lower than two of the healthy omnivore diet scenarios. Sensitivity analysis showed that carrying capacity estimates were highly influenced by starting assumptions about the proportion of cropland available for cultivated cropping. Population level dietary change can contribute substantially to meeting future food needs, though ongoing agricultural research and sustainable management practices are still needed to assure sufficient production levels.
