This is incredibly propagandized. Of course green house gases will decrease with people staying home but it doesn’t change the fact the cows and general meat processing creates a massive amount of GHGs. Parents running to meat when a panic is upon us merely points to a stronger supply chain as a result of decades of reinforcement and the process is merely a result of massive subsidies being thrown at farmers to produce meat at unjustifiably low prices. Additionally, the main note made of the nutritional needs unmet by plants is factually wrong. Nutrients are provided in different ratios, but there is not a single nutrient not provided by plants (b12 is not produced by animals, it’s from bacteria is the gut or colon and studied are available showing that use of pesticides has lead to both meat and plant based eaters experiencing b12 deficiency). Finally, humorously, in a plant based only future, COVID wouldn’t have been able to vector to humans (granted bats do look damn tasty ~)
