How is that bullshit? I am not vegan, but that’s just a scientific consensus and a major reason why plant diet is way lower carbon than a meat diet. If you need to grow plant food for your animal food, eventually you have to grow way more plant food.
Most animals raised for meat consumption are fed with crops, notably soy, not wild grass.
Thinking animals raised for meat only consume resources (land (first cause of biodiversity loss), plants, water, energy) that would not be useful to humans anyway is undoubtedly wrong.

Researchers Poore and Nemecek are a great source of meta-analysis information about those subjects. Check this summary here for example: http://environmath.org/2018/06/17/paper-of-the-day-poore-nemecek-2018-reducing-foods-environmental-impacts/

Let me know if I misunderstood your point.

We do not feed them food we can eat, it would be such a waste to do so. We literally feed them shit we cannot consume. Feeds are made from roots/stalks/inedible plants.

The vegan industry doesn’t like this, so they say well that land could be used for other things, when in reality it’s already being used for the food that we eat.

They are also fed grains and soy in varying percentage depending on regions and countries.
There is also still the use of land, energy, fresh water and the methane emissions typical of cows.

This is another break down of the above-mentioned study: https://ourworldindata.org/land-use-diets

You can see that indeed, the USA does better than other countries on not dedicating crops to animal feed, but it is still about 14%, while the world average is around 40%. Isn’t that a lot that could be earned back?

The majority of the land used for cattle grazing is not suitable for farmland. It’s either to hilly or rocky or just plain doesn’t have great soil. Not to mention the level of crops it would require to feed people and the amount of people who just cannot sustain on a all vegan diet. There is a reason we are omnivores and not herbivores.

Yes, but inefficiently.

You go eat some grass/roughage and tell me how well that fills you up.

It’s less important that such arguments be factually accurate than that they are superficially convincing enough to distract the person giving the argument from thoughts and feelings they are unwilling to process.
