This is also covered by the study and the article I shared above. It would require using more lands for crops that feed people, but that's ridiculously small compared to the land that would be regained from stopping animal agriculture, which is 75%. Just removing cows would do the vast majority of that.

Again the majority of the land used for cattle is not suitable for crops. So unless you plan on putting houses on that land it's not going to be used for anything anyways.

Crops for feed can be regained and if most pasture land is inappropriate for crops, some are, so we would gain from freeing those too. Furthermore, this land can be given back to biodiversity, which will also benefit us in the long term, if just protecting biodiversity for the sake of it is not a good argument for you.

O it would be great to have more biodiversity, we need all the insects we can get, but cows aren't killing off our insect populations, growing crops and spraying pesticides are. Which don't even get me started on organic...they use organic pesticides which are way more devastating to the environment.

Again, I am not vegan, I mostly advocate for reducing, not forbidding, consumption proportionally to ecological impact. If some people for medical reason require meat, I'm completely fine with it, this would likely be a small percentage of the current consumption.

In honesty, we need vertical farms and lab grown meat. If that could be pulled off then we'd be golden. I'm not against eating plants, but I'm not someone who likes that militant vegans come in and spew bullshit just because they want to feel morally superior to people who eat meat.

Omnivore, not obligate carnivore except for a few exceptions maybe, so we could use a low meat diet or a fully plant based diet fine.

The issue isn't that we can't, it's that the majority of people already eat like crap, which meat helps fill in the blanks. If we went to all plant based, people would still eat like crap and be missing vitamin D and protein.

Also a good chunk of us are already eating a low meat diet because that shit is expensive.
