Animal Foods of the Future

sectitle-featuresinsect saladSince the number of domesticated plants and animals is very small, it makes sense to find uses for more kinds of creatures, rather than trying to monocrop the environment for the few species we respect, while trying to eliminate the rest. In terms of animal foods, we rely mainly on four or five species of land creatures, plus many kinds of fish. Since there are at least three million animal species, it seems there’s a lot of God’s creation that we don’t like. Out of about 80,000 possible food plants, we depend to an enormous degree on just eight. And of these eight (wheat, rice, corn, potato, barley, cassava, sweet potato, and soybean), only cassava is not increasingly at risk from rising temperatures and UV radiation. But since many cultures of the world use different creatures than we do, there’s a decent chance we can expand our options by watching others.

Probably the most important source of food that we’ve tried to eliminate is insects. Insects make up at least 90% of all animal biomass on land. They’re the plankton of the terrestrial food chain, but as food we typically see them as beneath our contempt. Eating insects was traditional in many cultures. But recently, most people around the world got the idea, probably from the liberal media, that eating such meat is not respectable for modern man. As townspeople in Sabah state (of Malaysian Borneo) say of their forest-dwelling, insect-eating neighbors, “Eating insects is disgusting, primitive and weird.” At least TV shows like Fear Factor and Australia’s Bush Tucker Man tend to present it as challenging rather than depraved.

locust plaguejpgNaturally, people who are beset by plagues of locusts or grasshoppers have commonly eaten the insects, at least on occasions when these bugs were suddenly the only food available. The Jewish scriptures endorsed the practice, with certain rather unclear conditions: “The only flying insects with four walking legs you may eat are those with knees extending above their feet, [using these longer legs] to hop on the ground. Among these you may only eat members of the red locust family, the yellow locust family, the spotted gray locust family and the white locust family. All other flying insects with four feet [for walking] must be avoided by you” (Leviticus 11: 21–23) Therefore, there are such things as kosher locusts, and certain groups of Jews in locust-afflicted lands such as Yemen or Tunisia have long enjoyed them. The Midrash in Shemot Rabba suggests that when God sent a plague of locusts upon Egypt, many Egyptians actually greeted the insects with enthusiasm: “Once the locusts came, the Egyptians rejoiced and said ‘Let us gather them and fill our barrels with them.’ God then punished them further by taking even their locusts away: ‘Wicked people, with the plague that I have brought against you, are you going to rejoice?!’ Immediately God brought upon them a western wind … and none were left. What does it mean that none were left? Even those [locusts] that were pickled with salt and sitting in their pots and barrels were blown away …”

In Japan or Indonesia, rice farmers traditionally controlled grasshoppers in their fields by eating them. In southern Mexico, many farmers do the same. They avoid spending money on pesticides while gaining a food source that can be worth around $3,000 per year. Especially in Oaxaca state, people fry the grasshoppers (or chapulinas) with garlic, lime juice, and salt, mixed with an extract of the agave worm. They munch the chapulinas as a snack, or sprinkle them as a topping on tortillas with refried beans. With a similar attitude, the Paiute Natives of the US Southwest managed to stop the USDA Forest Service from spraying insecticides against pandora moth caterpillars, since these insects are a traditional Paiute food. Basically, these traditional farmers feel it’s inefficient to spend money on chemicals to destroy insects that have up to 75% protein, in order to protect crops that contain 14% protein or less.

festive ratsIn the 1970s, Thailand suffered a major plague of patanga locusts, and aerial spraying showed little effect. The government then urged people to eat the locusts, as had been done in the past. A publicity campaign promoted the use of locusts for deep-fried snacks, as a ground-up ingredient in crackers, or as a cooking sauce. The campaign basically worked. Patanga locusts became a popular food, and are no longer considered a major pest by most farmers. More recently, around 20,000 families in Thailand took up commercial cricket raising. These tiny ranches require only a few hundred square feet of yard space. The farmers make cricket hutches out of containers filled with loamy topsoil. They add cricket eggs on top, then cover the containers with grass, bamboo shoots, or egg cartons. Last they drape nylon netting over the hutch. As the crickets grow, they need only a little chick seed, some extra grass or weeds, and a little water. If the weather is warm, they’re ready to harvest in four to six weeks. In two villages of Thailand’s Khon Kaen province, 400 participating families raised 10 metric tons of crickets, and their income varied between $300 and $1,600 (US) each. The crickets sell well in urban markets, mostly as a fried snack that people eat with beer.

This kind of business represents a new micro-ranching of mini-livestock, which is vastly more efficient that traditional ranching of big herbivores. The big herbivores take around ten times more plant nutrients to make a kilo of meat than it takes to grow a kilo of edible bug protein. The insects require vastly less food and water, grow about six times faster than livestock herbivores, and reproduce thousands of times faster. Insect farming could be a much more productive, far less destructive use of land for feeding the world. We presently use about 26% of the planet’s ice-free land surface for herbivore pasture. And the animals’ feedcrop production requires a third of all cropland. In all, livestock ranching takes up 70% of all agricultural land use, and nearly 33% of the earth’s land surface. The costs in water, deforestation, soil erosion, and the contamination of the environment from pesticides, antibiotics, and methane gas are enormous. Maybe we could raise even more food on a relative microchip of that footprint. In that hope, Dr. Aaron T. Dossey founded a company called All Things Bugs, which conducted a research project named “Good Bugs: Sustainable Food for Malnutrition in Children.” In 2012, the Bill and Melinda Gates Foundation awarded this project its Grand Challenges Explorations prize. As for the space-age future, Japanese entomologist Jun Mitsuhashi (author of Edible Insects of the World) proposes that

“Edible insects may be used as space-travel food in the distant future. For long voyages to other planets, their cell culture will provide animal protein in a spacecraft, within which the area for the production of foodstuffs will be limited. If humans ever live in huge airtight domes on other planets, food production will have to be developed within the confines of the domes. Breeding of large livestock will not be practicable because of space limitations. The alternative will be to use insects to provide a source of animal protein. For such purposes, species such as silkworms, termites and flies have been suggested, taking into account the effective recycling of organic substances.”

For those who insist on redder meat despite having very limited budgets, the good news is there’s always rodents. Governments in central Africa encourage use of “mini-livestock,” such as Gambian giant rats or cane rats, to increase food supplies. The English aid agency Send a Cow has recently helped African families by soliciting Christmas gift donations of small farm animals such as rabbits, chickens, or cane rats. Concerning the popular cane rats, Kirstin Dunhill explained, “They’re much bigger than the rats we know in the UK and we fund them in Cameroon, where they are farmed.” She said that by making the jungle rats into livestock, the villagers find less need to hunt bushmeat in the forest. There’s less damage to forests from traditional slash and burn hunting methods, and less dependence on killing endangered species such as apes for food.

insect sushiIn southern India, the earth banks surrounding rice fields hold large numbers of burrowing mice, which live off the crops. Many high caste Hindus or Muslims wouldn’t think of eating them, but some communities such as Irula tribal people make a specialty of catching and eating such mice. The field owners offer these people contracts to harvest the rodent resource, for a win-win solution. A similar practice has grown popular in rural Thailand. Sala Prompin, a Thai rat seller, says he never deals in rats from cities or towns, but only those caught rice fields: “They are definitely clean.” Besides, Prompin advises, “It’s tastier than other meats—nothing can compare with rat.”

Perhaps this heralds the great commercial rodent farms of the future. However, when British food inspectors found that stores in the Ridley Road market were selling cane rat meat from Africa, Dr. Yunes Teinaz said “It is disgusting and outrageous that the local authorities don’t take action and remove this meat from the human food chain.” The Market’s shop owners were in denial. One of them said, “I don’t sell rats. I never sell rats … I don’t have any rats, why you come to video me?” Meanwhile, the French chef André Simon, in his Guide to Good Food and Wines, advised roasting black rats with a stuffing of breadcrumbs, minced rat livers and hearts, sweet herbs, and a touch of salt and pepper. For people of open minds, it’s just a matter of making the best of what you’ve got.
