There are two issues here. The first is the complete governmental 'head in the sand' absence of planning that farmers have been calling for for more than a year. They have been left high and dry by a government that promised what they are unable to deliver. (And yes, many of our local farmers did vote for Brexit and are now furious because they say they were lied to.)
The second issue is about the quality standards of British Meat, allied with changing eating habits. I think it is now inevitable that meat imports will rise and this may create a downturn in welfare standards for British foods.
These issues however have raised questions about the amount of meat we eat and increased awareness (as evidenced quite clearly on this thread) about how we treat the animals in our food chain - and that can only be a good thing.
We grow most of our own food (and I'm now feeling slightly anxious about power cuts in the future as I have three well-stocked freezers). We eat hand-caught fish supplied by our son, eggs from my daughter, sister-in-law, or the local farm shop and twice a year we buy a whole deer that my husband skins and butchers himself. We used to buy a piglet that was fostered by a friend on his smallholding, then both killed and butchered at a small facility nearby; sadly our friend sold his property so until we can find a similar situation we rarely eat pork any more and when we do it's reared up the road by an organic farmer.
