If factory farming was banned the cost of meat would rise substantially and we would probably eat less of it. This would have the double benefit of improving animal welfare and improving the health of millions so bring it on.

@Athena Firstly thank for your polite response, not something we always get here. Whilst I agree that eating processed food and junk food are a much greater health risk than eating meat, the need for cheap meat has meant that it now mostly comes from factory farmed chickens and pigs and cattle in feedlots. Leaving aside the animal welfare aspect the animals have to be treated with drugs to keep them healthy which we can then ingest.
I was brought up in a time when dinner was "meat and two veg" with fish once a week but the meat was not intensively reared and we knew where it came from
I now eat fish much more frequently and have at least a couple of meat free days a week.
If we have a trade deal with the US after Brexit it is likely that we will be pressured into buying chlorine dipped chicken and beef from cows treated as a matter of course with antibiotics and there are obvious reasons why they have to be treated that way
there is a govt initiate here to have us eating less meat for health reasons
This link gives some interesting points
