unfortunately this is just propaganda.
you might actually want to read the methodology (on the few which do declare it) they often include things like rain water for meat, but not for vegetables. they often use massive feedlots in America to get the worst possible stats for meat, but use a tiny sustainable farm for veg stats, they totally ignore calories and nutrients. Its as bad as there’s a lot comparing a kilogram of vegtables compared to a kilo of meat, despite the vegetables have maybe a couple of hundred calories at best.
That ruminant animals when not in massive feedlots, like in a lot of the Uk (all the mountains national parks that have thousands of sheep on for example) are not only on land that cant easily be farmed for grains, but actually improve the soil and sequester carbon into the soil.
They misrepresent the amount of actual bioavailable nutrients in plants compared to meat.
they ignore land, Globally we have used nearly all available plant agricultural land up, without cutting down rainforests etc, we however have plenty of unused grazing land left for animals.
you might want to look into nutrition research that shows vegan and even vegetarian is bad for your health, the research from the "60s that showed benefits some of it was floored, other health benefits came not from being a vegan but the lack of processed foods, modern research shows that vegans are far more unhealthy than the normal diet (which is also really bad), now that so much vegan and vegetarian processed food is available.
Due to the war on meat, the public at large is now deficient in many micro nutrients (often plants contain the wrong form which is poorly absorbed, or poorly converted in the body, then you have things like oxilates that compound the issue), doesn’t kill us in the short term, but is part of the rise of elderly diseases. (although there have been several cases of parents killing children due to vegan diet)
you may want to look into the Seventh Day Adventists Church and see how far reaching their tendrils are on the food chain, research and education, all of which is extremely biased due to their religious believes.
you also may want to look at how devastating mass monocrop agriculture is, as well as agriculture in general, with fertilisers, pesticides, and the death of the soil, run off into streams and rivers etc.
Then how far food has to come from to be vegan, it is almost impossible to be vegan eating purely local and requires shipping from around the world. Where it is pretty easy to get all your micronutrients from a meat based diet(if you eat offal) from a dozen or so miles of your house.
in summary most modern farming is bad, but the propaganda fro reducing meat is quite literally killing thousands a year, whilst not actually achieving what they say environmentally.
Can you be vegan, absolutely but its damn hard work to be healthy into old age and requires a global supply chain.
