I've signed too but I bet most of us will continue buying products regardless, as it's far too time consuming to read the often long list of ingredients on the back.
Those who need readers might have to scrabble around in their bag and then remember that they left them at home.
All well intentioned in the run up to Christmas, swept along on a tide of goodness, however, during the rest of the year when life gets in the way of environmental matters, we will forget.
I'm being realistic.
See how much you'll have to pass up
of the food you normally buy.
It will take you more than twice as long to shop as you'll read labels, find it has palm oil then have to read a lot more to find items without that ingredient.
Then we need to talk about dyes, parabens and sulfates.
I'll ask the question in March. See how much you have managed to change your shopping habits by then.
