Food Waste--A Global Tragedy

I have recently finished reading Waste: Uncovering the Global Food Scandal, by British author Tristram Stuart. His analysis features the UK food distribution system, with significant contributions about the U.S. system and other European countries. The facts are scandalous, as he says. This book is well worth the reading. Here are a few highlights.

Food waste starts right at the farm, particularly with contract growers for supermarkets. Supermarket chains order x pounds of something, like carrots, to be delivered by y date, but they can reduce their order if by that time, demand is down, they already have too many, or for any other reason.

If the grower does NOT deliver x pounds of carrots at that time, he/she is liable to lose their contract for the next year. Weather or crop failure is not an excuse, so the grower who wants to keep their contract will plant more rows of carrots than needed.

If the supermarket chain reduces its order arbitrarily, the grower is left with excess carrots. Or if there is a bumper crop, probably the other growers have one too. The residual value of all those extra carrots is probably not worth the trouble of packaging, shipping and marketing, so they are often plowed under.

Next, a tremendous amount of food waste is caused by "aesthetic" considerations. Carrots must be perfectly straight, so they all fit neatly into those bags. Non-straight carrots are dumped or sold for animal feed, or in the U.S. are sent to be milled into "baby carrots". Potatoes that are too big: out they go. Apples that are too small: out they go. Any produce item with a little mark on it, a slightly funny color, etc., out they go. In some cases they go for animal food, in some cases particularly in Britain, they are used as feedstock for methane generation. But often they are just composted or plowed under.

It gets worse.

Sell-by dates are the culprit in much meat and dairy-related waste. These are very conservatively set; most foods are good for another several days or even a week or more. This factor combines with the desire of stores to be fully stocked with every possible item, even perishable, regardless of level of sales.

Between the overstocking and the pessimistic Sell-by dates, packaged entrees, sandwiches, salads, and similar foods are usually just dumped. Stuart says that in the U.K., the dumpsters are generally locked to prevent the poor from getting their hands on the food. If not that, the foods are emptied from their packaging and stirred all together with non-food waste to make them unusable. Due to landfill fees in the U.K., more of this waste is going to methane generation, generating pennies on the dollar of their worth as food for humans.

The loss to human food by dairy and meat waste is multiplied by the tremendous amount of human food (corn, soy, wheat, etc.) fed to conventional livestock.

Other sources of food waste include eating too much (waistline as waste), general dislike of organ meats (though some of this goes into pet food), the packaging of perishable food in amounts that are too large for singles or couples to use before they go bad, and the tendency of many children to take a bite of something and throw it away. And the waste of by-catch for seafood runs up to 90% for some items such as wild-caught shrimp. Waste of seafood is particularly tragic since many species are drastically overfished.

Another cause is poor household planning: buying what's on sale instead of what the family will eat; forgetting what you have in stock; getting busy or tired and eating out instead of eating what's on hand.

Stuart has done a great deal of research, and finds that counting waste sources from farm to garbage can, approximately 50% of food production is wasted in the sense that it is does not meet its destiny as human food. The U.S. has more than four times the amount of food required by the nutritional needs of the population (some is fed to livestock). The production of surplus food is a huge contributor to greenhouse gas emissions; the planting of trees on land used for wasted food would offset half to all of man-made emissions.

The good news is that enough food is produced now to give everyone in the world enough to eat. The bad news, of course, is that we do not do that. U.S. households spend about 9% of their income on food, half of what was spent a few decades ago. Food is SO CHEAP for most people that they do not value it. Convenience trumps instrinsic value. It must be especially galling for the hungry, especially in our wealthy nation, to know that tons of perfectly edible food end up in landfills. And it is not showing respect to the animals, the farmers, the land, the Earth, when we treat these resources as unimportant.

So what can we as individuals do? I welcome you to join me in trying to reduce the food waste in your own household. And I welcome suggestions from readers for specific and general ideas.

After all, it isn't just food, it's lives. Lives of food animals, lives of farmers, lives of wild animals whose habitat has been taken away for more soybeans or oil palm or whatever. It's past time for us to consider the Earth and its dwellers as precious.

* Be a better manager. Be aware of your stocks. Use or preserve items before they go bad. Buy only what you will use. There are a multitude of ways to use or preserve food items, and I'll discuss a few in upcoming posts.

* Buy direct from farmers, through CSAs, or through farmers markets or cooperatives. This will eliminate much of the "aesthetic" waste from the supermarkets. The crooked carrot and knobbly potato are perfectly good food.

* Buy grass-fed or pastured meat, dairy and eggs when you can. This will free up more food for humans, and will reduce the need for intensive monocultures.

* Teach your children to respect food. One way is to let them have a garden. The carrot they grew is more precious than the carrot from the supermarket. Or take them to a small farm or CSA, so they can see the plants and animals. Model respect for food in your own behavior.

* If you have fruit trees or shrubs in your yard, work at putting that harvest to good use, not just letting it fall on the sidewalk or be swept into the garbage.

I'll talk about some of the ways to reduce food waste on the community level soon.

If we are parents, guardian or sister or brother we must teach our children on how to respect food and explain to them how important it is and how it became a food that are ready to eat and how many people give a hard work to make it. We must be responsible enough and it should begin it in our home.
