I'm not saying that soil health isn't a problem for making vegan food. Since their is a significant less amount of crop farming needed to feed a vegan population we would significantly cut the amount of farmland needed and free up a significant amount of soil.
Being vegan as well as fighting for animal rights we of course demand a more sustainable food system and everyone in it getting paid fairly.
Biggest step up would probably be for vertical farming to go mainstream. It's not too great for meat industry, but for vegan industry it works more than well.
Another step up will be mass produced lab grown animal proteins/oils/fats (meats) which a healthy human diet requires. On other hand we can still also have a remnant of meat industry be left alive, which is to repurpose animals that have died of natural causes, rather than inhumanely farming animals enmasse.
I mean we don't need animal proteins for a healthy human diet...

And what does this have to do with my previous point?
Basically the study found that previous research on TMA's (which are abundous in animal protein) saying they're harmful to humans, may actually be wrong, and that they're in fact beneficial to our health. (edit 2: due to rapid bilophia production in the microbiome, which converts it to DMA?)
I'm not a microbiologist though, and I hope someone with background could expand this into an ELI5.
Edit: If you scroll down on the page, you can find a figure (FIG 1) which gives a more easy to understand view on the study and the impacts animal proteins were found to have.
