Cooking with tins?

I caught a bit of The Food Programme today - about Eco-labelling. https://www.bbc.co.uk/programmes/m0014648
They asked someone to choose which was the more Eco-friendly - rashers of bacon from UK pigs or plant based "meat" made from soya grown abroad. I may have this wrong as I was driving at the time!
The Eco-labellers take all sorts of things into account - like transport costs, how much water is used in production, whether a fruit grown abroad (where conditions are right) and flown to the UK is better, or worse, than a fruit grown close to home but in a heated greenhouse. (I may have made that last bit up).
I can't help feeling that the most eco-foods are the ones we grow in our own gardens where we have control over the input and no need to use additives.

I have tried plant based eco bacon before. I don't care how eco friendly it is they can stick that disgusting stuff where the sun don't shine I try to be eco friendly wherever posssible but taste has got to play a big part in whether I find it edible and would buy it agan.  

Yep, I agree veggie, I greatly enjoy food from my allotment where I can be sure of its lineage.
