Some consumers may choose veganism, or a pescatarian diet, but meat, eggs and milk, offer crucial sources of much-needed nutrients which cannot easily be obtained from plant-based foods, a new report issued on Tuesday by the UN’s Food and Agriculture Organization says.
Yeah you can get vitamin A from plant foods, usually in beta carotene form. Though I think there are other forms of it as well. But the body must first convert this to retinol before using it. If you are eating enough food, this isn't really a problem for most people, but if you are at risk of starvation or anemic, it is an issue.
B12 can be obtained though food containing nutritional yeast like Marmite.
i feel that the stop starving people thing should come first before the animal agriculture is good actually thing
