Is that an argument? Many also eat meat and starting to treat animals well is a step in the right direction. Perfect is the enemy of good.

Animals rape each other, right?

Yes because I forgot how animals can consent to carry on their species...the fuck does that have to do with them eating meat?

Did you read your own source?

The global food system generates GHG emissions from multiple sources. Major sources include land clearing and deforestation, which release carbon dioxide (CO2) and nitrous oxide (N2O); production and use of fertilizers and other agrichemicals, which emit CO2, N2O, and methane (CH4); enteric fermentation during the production of ruminants (cows, sheep, and goats), which emits CH4; production of rice in paddies, which emits CH4; livestock manure, which emits N2O and CH4; and combustion of fossil fuels in food production and supply chains, which emits CO2. In total, global food system emissions averaged ~16 billion tonnes (Gt) CO2 equivalents year−1 from 2012 to 2017

It's the 4th paragraph down??? If you think plants don't require fertilizers, farm equipment burning fuel, and land clearing...then I've got a bridge to sell you.

We next explore how global food system GHG emissions might be reduced through five strategies that target food supply and demand: (i) globally adopting a plant-rich diet [here modeled as a diet rich in plant-based foods that contains moderate amounts of dairy, eggs, and meat, such as a Mediterranean diet or planetary health diet (15)]; (ii) adjusting global per capita caloric consumption to healthy levels; (iii) achieving high yields by closing yield gaps and improving crop genetics and agronomic practices; (iv) reducing food loss and waste by 50%; and (v) reducing the GHG intensity of foods by increasing the efficiency of production, such as by altering management regimes (e.g., precise use of nitrogen fertilizer and other inputs) or technological implementation (e.g., additives to ruminant feed).

So basically, fat people are a huge cause for our increase in GHG and people who waste food. Even their plant based diet, still has meat in it.

You're other two links gathered data and has a ton of assumptions in it because the majority of cattle land cannot be used for crops, it's either way to rocky, or the soil is complete shit. You do realize as well these estimates include the literal millions of acres that Australia use for free range cattle, and the same as in the USA right?

Global mean land used to produce 1000 kilocalories of different food products. This is measured in meters squared per 1000kcal (m² per 1000kcal).

So a cow which will eat straight up anything you cannot consume is going to roam in this large vast areas, and because it does so, all of a sudden it's 1000k takes up a lot more space. Space which cannot be used for crops.
