If we do that to fruit and vegetables, you bet we can do it to animals too. Liver, lungs, heads, tails, kidneys, testicles, all of these things which are traditional, delicious and nutritious parts of our gastronomy go to waste. Offal consumption has halved in Britain and America in the last 30 years. As a result, this stuff gets fed to dogs at best, or is incinerated. This man, in Kashgar, Xinjiang province, in Western China, is serving up his national dish. It’s called sheep’s organs. It’s delicious, it’s nutritious, and as I learned when I went to Kashgar, it symbolizes their taboo against food waste. I was sitting in a roadside cafe. A chef came to talk to me, I finished my bowl, and halfway through the conversation, he stopped talking and he started frowning into my bowl. I thought, “My goodness, what taboo have I broken? How have I insulted my host?” He pointed at three grains of rice at the bottom of my bowl, and he said, “Clean.” (Laughter) I thought, “My God, you know, I go around the world telling peop

Can I have a show of hands if you have a loaf of sliced bread in your house? Who lives in a household where that crust — that slice at the first and last end of each loaf — who lives in a household where it does get eaten? Okay, most people, not everyone, but most people, and this is, I’m glad to say, what I see across the world, and yet has anyone seen a supermarket or sandwich shop anywhere in the world that serves sandwiches with crusts on it? (Laughter) I certainly haven’t. So I kept on thinking, where do those crusts go? (Laughter) This is the answer, unfortunately: 13,000 slices of fresh bread coming out of this one single factory every single day, day-fresh bread. In the same year that I visited this factory, I went to Pakistan, where people in 2008 were going hungry as a result of a squeeze on global food supplies. We contribute to that squeeze by depositing food in bins here in Britain and elsewhere in the world. We take food off the market shelves that hungry people depend on.

So I want you to imagine that these nine biscuits that I found in the bin represent the global food supply, okay? We start out with nine. That’s what’s in fields around the world every single year. The first biscuit we’re going to lose before we even leave the farm. That’s a problem primarily associated with developing work agriculture, whether it’s a lack of infrastructure, refrigeration, pasteurization, grain stores, even basic fruit crates, which means that food goes to waste before it even leaves the fields. The next three biscuits are the foods that we decide to feed to livestock, the maize, the wheat and the soya. Unfortunately, our beasts are inefficient animals, and they turn two-thirds of that into feces and heat, so we’ve lost those two, and we’ve only kept this one in meat and dairy products. Two more we’re going to throw away directly into bins. This is what most of us think of when we think of food waste, what ends up in the garbage, what ends up in supermarket bins, what ends up in restaurant bins. We’ve lost another two, and we’ve left ourselves with just four biscuits to feed on. That is not a superlatively efficient use of global resources, especially when you think of the billion hungry people that exist already in the world. 07:15

One morning, when I was feeding my pigs, I noticed a particularly tasty-looking sun-dried tomato loaf that used to crop up from time to time. I grabbed hold of it, sat down, and ate my breakfast with my pigs. (Laughter) That was the first act of what I later learned to call freeganism, really an exhibition of the injustice of food waste, and the provision of the solution to food waste, which is simply to sit down and eat food, rather than throwing it away. That became, as it were, a way of confronting large businesses in the business of wasting food, and exposing, most importantly, to the public, that when we’re talking about food being thrown away, we’re not talking about rotten stuff, we’re not talking about stuff that’s beyond the pale. We’re talking about good, fresh food that is being wasted on a colossal scale. 02:04

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.” I went to the local baker and took their stale bread. I went to the local greengrocer, and I went to a farmer who was throwing away potatoes because they were the wrong shape or size for supermarkets. This was great. My pigs turned that food waste into delicious pork. I sold that pork to my school friends’ parents, and I made a good pocket money addition to my teenage allowance.

What that tells us, quite simply, is that GDP is not destiny. We have countries that are underperforming on social progress, relative to their wealth. Russia has lots of natural resource wealth, but lots of social problems. China has boomed economically, but hasn’t made much headway on human rights or environmental issues. India has a space program and millions of people without toilets. Now, on the other hand, we have countries that are over-performing on social progress relative to their GDP. Costa Rica has prioritized education, health and environmental sustainability, and as a result, it’s achieving a very high level of social progress, despite only having a rather modest GDP. And Costa Rica’s not alone. From poor countries like Rwanda to richer countries like New Zealand, we see that it’s possible to get lots of social progress, even if your GDP is not so great. 10:00

Now this seems a bit strange. Economic growth seems to have really helped in the fight against poverty, but it doesn’t seem to be having much impact on trying to get to the Global Goals. So what’s going on? Well, I think there are two things. The first is that in a way, we’re the victims of our own success. We’ve used up the easy wins from economic growth, and now we’re moving on to harder problems. And also, we know that economic growth comes with costs as well as benefits. There are costs to the environment, costs from new health problems like obesity. 08:27

Do you think the world is going to be a better place next year? In the next decade? Can we end hunger, achieve gender equality, halt climate change, all in the next 15 years?

We, therefore, pledge to do all that we can, knowing we’ll fail on occasion, to restore compassion to the center of our lives (at least in this course and during this semester) and attempt to engage with our colleagues in this course with compassion. This means we will work to think first of others, their benefit, their well-being, and their learning, knowing that others are compassionately working for our benefit.

It is also necessary in both public and private life to refrain consistently and empathically from inflicting pain. To act or speak violently out of spite, chauvinism, or self-interest, to impoverish, exploit or deny basic rights to anybody, and to incite hatred by denigrating others—even our enemies—is a denial of our common humanity.

The principle of compassion lies at the heart of all religious, ethical, and spiritual traditions, calling us always to treat all others as we wish to be treated ourselves. Compassion impels us to work tirelessly to alleviate the suffering of our fellow creatures, to dethrone ourselves from the center of our world and put another there, and to honor the inviolable sanctity of every single human being, treating everybody, without exception, with absolute justice, equity, and respect.

Act toward and write to others as you would want them to do for you if the roles were reversed Take responsibility for the effects of your words and actions on others, even when your intentions were not to cause them harm Listening Listen attentively and intently (with intention to understand) first, and forming an opinion after you fully understand their point of view Be open-minded toward others’ ideas and understanding of their backgrounds Pay attention to your use of language (try not to be defensive) When you’re uncomfortable, speak up and tell others, so they know Responding Mindfully respond to others’ ideas (acknowledge someone’s ideas before presenting your own) Vocally affirm that you respect and empathize with those around you Use a calm and collected tone of writing; be careful with your word choice; avoid aggressive language, and don’t use harsh words Encourage compliments and be nice to others Aim to educate
