It's certainly sobering to think that British consumers waste roughly a quarter of the food we buy. Or to put it another way, we funnel £12 billion a year from the supermarket through to our rubbish tips, costing each household an average of £480.

Painting is just another way of keeping a diary.

Liver, lungs, heads, tails, kidneys, testicles, all of these things which are traditional, delicious and nutritious parts of our gastronomy go to waste.

Good food for free has been the holy grail of foragers since our ancestors first climbed down from the trees.

Are we not all desperate one way or another?

The job of uncovering the global food waste scandal started for me when I was 15 years old. I bought some pigs. I was living in Sussex. And I started to feed them in the most traditional and environmentally friendly way. I went to my school kitchen, and I said, 'Give me the scraps that my school friends have turned their noses up at.'
