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 would love to find that report....I've a friend that bangs on about plant based....nowt wrong with beans if you don't want meat.


I don't use many tins to be honest. I've not bought tomatoes for years....I love beans but I always use my own. 
What I do use is sweet corn, chickpeas, tuna and I couldn't live without sardines!!!
I also buy tinned rice pudding  the boys take it windsurfing for carbs. It's so easy in a packed lunch
