To all the people saying that soya is grown for cattle...
We have cows. We used to use soya in their feed but no longer do. It's common knowledge in farming that soy cattle feed generally contains the parts of soya that humans can't eat. The cattle eat the husks, the waste, often it isn't actually being grown for them. Despite this, we decided to cut it out completely a few years ago and feed stuff grown in this country now. Much of it from our farm or the local area, when they are not outside.
Contrary to popular farmer bashing that seems to go on at the moment, we are constantly looking at how we can improve the way we work. We are subject to regular inspections, we have targets to meet or we will lose our contracts and we are part of larger groups who are constantly trying to be the best we can, whether it's reducing carbon footprint, welfare, improved technology or whatever. We have 'wild' areas on our farm, beehives, wooded areas, a river, loads of hedgerows and wild animals. We've had these as long as I can remember, 'wilding' is not suddenly a new idea, as the government would have everyone think.
There seems to be a message at the moment that vegan = good for the environment and as others have said upthread, that's not always true. The carbon footprint and amount of water needed for some of these foods can both be extremely high. The media seems to only see livestock as carbon emitters but forgets about the whole carbon cycle. The other point I'd make is that surely the empty shelves we've seen at times over the past 18 months should make everyone realise how important it is to produce a high percentage of food in our country. Livestock are part of that and many of them are fed solely on grass, hay, silage or grains made in the UK.
Eating locally produced food, whether plant or animal based, is surely best, not just for the environment as the OP says but also for the future of our country. By all means be a vegan, but don't spread myths about farming as there are plenty out there that are not true.
