Scientists Propose Insect Farming Instead of Cattle

Meet me at Five Guys for a Beetle Burger, or bring your lunch and pack a peanut butter and aphid sandwich. I guess if they can grow them large enough, we could have grasshopper filets. So, what would be the insect equivalent of foot and mouth disease, pod and mandible? Or are we talking Mad Roach? Move over, Long Horn, cuz here comes the Rhinoceros Beetle in droves. Would PETA mind if we just cloned them all at ridiculous sizes in space? Then we can augment their brains with some hardware and network them by their antennae (although it's a chemical signal, how does that translate into binary?), program and march them around, drive them as SUVs, employ them as day laborers, whatever.

Article from the Netherlands suggests insect farming would cut down on greenhouse gases. I'd like to tie a bib on Al Gore for this one.

Meat producers should replace cattle with insects, scientists say

Scientists in the Netherlands have discovered that insects produce significantly less greenhouse gas per kilogram of meat than cattle or pigs. Their study, published in the online journal PLoS One, suggests that a move towards insect farming could result in a more sustainable - and affordable - form of meat production.

The rearing of cattle and pigs for meat production results in an estimated 18 percent of global greenhouse gas emissions. With worldwide consumption of beef and pork expected to double by 2020, alternatives are being investigated. Of these, perhaps the most notable has been the development of "in-vitro meat" which is lab-grown tissue not requiring the production of a whole organism. Initiated by NASA as a form of astronaut food, in-vitro meat production took its first steps in 2000 when scientists used goldfish cells to grow edible protein resembling fish fillets. Since then, turkey and pig cells have been used to create spam-like substances, and Time Magazine has included in-vitro meat in its list of the top 50 breakthrough ideas of 2009.

In addition to the environmental impact of current meat production techniques, scientists believe that the inevitable increase in price as population-driven demand grows will ultimately result in traditional meat products becoming unavailable to many people around the world.

However, if the idea of eating meat grown in a lab doesn't appeal to you, there is another option.

Researchers at Wageningen University in the Netherlands looked at mealworms, house crickets, migratory locusts, sun beetles, and Dubia cockroaches, and for the first time quantified the amounts of methane (CH4) and nitrous oxide (N2O) released per kilogram of insect meat. They found that the amounts of gases released by insects to be much smaller than those released by cattle and pigs. For instance, mealworms produce between ten and a hundred times less greenhouse gas emissions per kilogram than do pigs. Ammonia levels also declined significantly.

The scientists attributed the decrease in emissions to the insects' more efficient use of food. Because they aren't warm-blooded, what insects eat is aimed directly at body growth rather than maintaining a stable body temperature.

While the results are promising, the researchers caution that more study needs to be done in order to determine the impact of insect-farming on the entire production chain.
