Animal farming poses a lot of problems in our modern world. It is responsible for about 15% of worldwide greenhouse gas emisions, with an important of that part being methane, a gas with a sorther lifetime than carbon dioxyde in the atmorphere but that's also considerably more potent as a greenhouse gas. Because the demand for animal products is so high, farmed animals aren't fed solely on agricultural waste but also on grains and soy grown specifically for livestock, which causes a large part of the world's farmland to be dedicated to animal agriculture, which in turn causes habitat loss for wild animals and prevents effective carbon sequestrations due to these lands being denied the ability to grow into forests. Farmed animals are also fed the majority of antibiotics in the world, which is a threat to public health because it promotes the development of antibiotic-resistant bacteria. And of course it is very cruel, with every year billions of animals being killed in a gory, painful slaughter at a fraction of the lifespan they could experience otherwise, generally after a short existence of incomfort, confinment and often mutilations.

To solve these problems, we can stop relying on livestock for our food system. That implies to know about the logistics of farming without animals nor animal inputs (like manure) and suggest a new, evidence-based farming and food system.

Vitamin B12

Because the only vegan source of vitamin B12 is bacteria grown in a lab, it's important to make sure everyone would be able to get enough of it. It's reasonable to assume in a vegan world that a wide range of different foods would be fortified with it.
