you've only got to see the Arla advert currently on TV which tells you all cows are 'free range'
and therefore all milk is free range!
Don't shatter the public perception just yet, things are fragile enough.
just keep the message simple
See your point but can we really expect 'the public' to care about farming and food if what they are being marketed and what they are being sold is totally different, why would you bother to think about what you are buying? One thing to make it look the farms look modern and tidy, another to sell a completely different product than what is marketed. A bit like the difference between Coca-Cola marketing their product as healthy vs just declining to mention it is full of sugar, one is misleading the other is marketing.
