Quotes from Tristram Stuart

Often, farmers have difficulty finding secondary markets for their outgrades and have no choice but to leave fresh produce unharvested to rot in the field. Gleaning Network U.K. coordinates teams of volunteers with willing farmers across the U.K. to direct this fresh surplus produce to charities that redistribute it to people that need it most.

Every week, I heave open a supermarket skip and find therein a more exotic shopping list of items than I could possibly have invented - Belgian chocolates, ripe bananas, almond croissants, stone-ground raisin bread - often so much it would have fed a hundred people.

Cutting food waste is a delicious way of saving money, helping to feed the world and protect the planet.

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.'

In Japan, Taiwan and South Korea, the government in a matter of years has put a lot of energy behind recycling food waste as livestock feed. It's environmentally friendly, it provides cheap livestock feed for the farmers in those parts of the world, and it avoids sending the food waste to landfill.

We domesticated pigs to turn food waste back into food. And yet, in Europe, that practice has become illegal since 2001 as a result of the foot-and-mouth outbreak. It's unscientific. It's unnecessary. If you cook food for pigs, just as if you cook food for humans, it is rendered safe. It's also a massive saving of resources.

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.

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

Offal and offcuts such as head and feet can be picked up for next to nothing, and eating them helps to avoid waste.

The Feeding the 5000 campaign is inviting food businesses to sign up to the principles of the Food Waste Pyramid tool, which illustrates a simple set of steps that any food business can take to avoid and reduce food waste.

In the United States, under 3 percent of municipal food waste - so that's the food scraps that goes into people's garbage cans - actually gets recycled. If you go to a place like South Korea, the exact reverse is the case. It's about 3 percent that doesn't get recycled.

Supermarkets didn't even want to talk to me about how much food they were wasting. I'd been round the back. I'd seen bins full of food being locked and then trucked off to landfill sites, and I thought, surely there is something more sensible to do with food than waste it.

When is population going to become an accepted part of the food debate? If it's fine to encourage people to think about halving their meat consumption, can we really not cope with a conversation about how many children we have?

Of course, I prefer organic farming to chemical-dependent farming, but sometimes absolutist organic prescriptions go too far. I don't even rule out the possibility of genetic modification generating some benign ideas, as long as we can keep them away from monopolists such as Monsanto.

Who cares if a carrot has a slight bend? They're all the same when they end up on the plate.

The purpose of farming is to deprive other species of the land and sequester it for our own use. But by perfecting the art of monoculture, it has become too easy for us to exterminate everything else, leaving no wild plants, no food for insects, and a barren land for birds.

A hunk of beef raised on Scottish moorland has a very different ecological footprint from one created in an intensive feedlot using concentrated cereal feed, and a wild venison or rabbit casserole is arguably greener than a vegetable curry.

Heartless though it may seem to some, among the least harmful things to eat are sustainably culled wild animals. In the absence of natural predators, deer populations in parts of Britain have reached such dense numbers that the woodlands they browse fail to regenerate.

It is all very well for 2% of the population to live in a monastic state of meatlessness while everyone else gorges their way towards environmental meltdown or the nearest heart clinic. Vegetarianism is good for the willing minority, but not much use as a campaign tool.

Food redistribution is one of the best win-win solutions for food waste avoidance. Food companies can often save money by donating food rather than paying the £80 or so per tonne in landfill tax and disposal costs.

As human pastoralists discovered 8,000 years ago, raising animals can be an efficient way of harnessing otherwise unusable resources such as grass.

Food redistribution is economically sensible, ecologically pressing, and socially responsible; it is high time food corporations woke up to it and governments started funding the organisations that facilitate it.

As the words of my book, 'The Bloodless Revolution,' accumulated, I envisaged a parallel growth: the stack of pages they would have to be printed on, thousands of times over; every page representing a slice of forest, a belch of fumes and a squirt of toxic ink.

Once food gets into our fridges, larders and kitchens, ensuring that it gets used up before going off seems like an obvious thing to do - but it's alarming how many millions of tonnes are simply chucked because we don't keep track of the food we've spent our money on.
