Interrobang You are aware there is no ethics in any mass farming or in modern consumption?
Soy, whether for cattle or people, is destroying rainforests and kicking indigenous people of their lands as is the new popular fad of quinoa which is literally starving the groups that have lived off of it for centuries because the West has made the price so high.
Mass growing of wheat and the current products used to increase yields has destroyed the food sources of multiple pollinators that have nosedived and compounded because some pollinators are being transported from farm to farm to pollinate foods has destroyed many other pollinators. The monocultural farming methods needed for farmers to make enough money to survive is environmentally destructive (and still often leads to most farmers and their workers being in desperate poverty which is violence in and of itself).
Most foods picked worldwide are picked by exploited workforces, often migrant workforces with no rights. Not just food from developing countries which are often brought up, in the US about a quarter of food will be collected by those under 18 and cases have found children as young as 6 working full days to pick food. There are companies that will bring in undocumented workers, pay them crap because they can't complain (or force them to for free to pay 'debts') and when they get caught and sent back, the company just brings in the next batch and death rates are high. Even normal farmers have far higher death rates because of ho hard they need to push to survive. This has been seen worldwide, this has been seen in the UK. Those people collecting the vegetables and pulses that make the most ethical and unprocessed vegan diet deserve just as much consideration as the animals when considering ethics, yes?
And that's before we get into Western countries taking away people's livelihoods and food to make it more profitable without punishment (best example is Haiti, entire food system screwed and an entire species destroyed to force the importing of a foreign species that needs far more care in that environment to make several companies more money).
Being vegan does not get one out of the major ethical problems in the food industry systems - and in fact many vegan fads have made things worse around the world. There is no such thing as ethical consumption in modern-late capitalism, the system is set up to maximize exploitation of people to maximize profits. Going on about dairy industry conspiracies without recognizing that the entire food system is built on exploitation, blood, and lies of values, grinding farmers and other agricultural workers at the bottom in a system that will dangle labels to consumers for us to feel better without any real change.
Individuals will have to make their own best choices to survive and thrive as best as one can within the systems we have and find ethical guidelines they can live with, but the whole thing needs to be taken apart and new built - just taking animal consumption out of the picture isn't a real global answer (and many organizations that have pushed in on indigenous populations who already had sustainable practices and prevented hunting have caused starvation and increase in prices for other foods which said groups have done nothing about).
