Replace cattle? Edible insects produce smaller quantities of greenhouse gases
(PhysOrg.com) -- Insects produce much smaller quantities of greenhouse gases per kilogram of meat than cattle and pigs. This is the conclusion of Dutch team of scientists at Wageningen University, who have joined forces with government and industry to investigate whether the rearing of insects could contribute to more sustainable protein production. Insect meat could therefore form an alternative to more conventional types of meat.
Cattle farming worldwide is a major producer of greenhouse gases. For the assessment of the sustainability of insect meat, the researchers at Wageningen University quantified the production of greenhouse gases of several edible insect species. The results of the study were published in the renowned online journal PLoS ONE on 29 December.
The research team has for the first time quantified the greenhouse gases produced per kilogram of insect product. The gases concerned were methane (CH4) and nitrous oxide (N2O). The results demonstrate that insects produce much smaller quantities of greenhouse gases than conventional livestock such as cattle and pigs. For example, a pig produces between ten and a hundred times as much greenhouse gases per kilogram compared with mealworms. Emissions of ammonia (which causes the acidification and eutrophication of groundwater) also appear to be significantly lower. A pig produces between eight and twelve times as much ammonia per kilogram of growth compared to crickets, and up to fifty times more than locusts. An additional advantage of insects over mammals is that they convert their food into meat quicker.
The study indicates that proteins originating from insects in principle form an environmentally-friendly alternative to proteins from meat originating from conventional livestock. Further research is required to ascertain whether the production of a kilogram of insect protein is also more environmentally friendly than conventional animal protein when the entire production chain is taken into account.

Maybe they could hire Tom Cruise as a spokesman now that he has become an embarrassment for the Church of Scientology. Maybe they could form an alliance with The Church of Jesus Christ and the Latter Day Saints as they seem to have a set principles in place for planetary management as they are all going to have a planet of their own to run in the future.

More idiots rating good logical comments down? Or are you dirt and bug eaters? This comment makes perfect sense and is about what I was going to say.
Plants don't give off greenhouse gases. Beans and corn or rice make a complete protein. It should easily be possible to not only create plants that are complete protein meat substitutes but also have the right texture to substitute for meat. If an animal can do it then a meat plant is possible.
Of course if we could grow 2ft bugs too let the bug eaters have them. I don't have much of a craving for bugs myself but evidently the people who rated QC's post down do.

Heat is simply the vibration of molecules due to contained energy. If I was going to guess at how that worked I'd think it'd be easier to simply arrange molecules at a particular energy than to arrange them at one energy, then energize them further. So I'd think it'd be synthesized hot. Good question.

Thanks for the info Ethelred.
Personally I believe a stable crop of insects would benefit humanity. Majority of this planets food relies on the sun. In the event of a global disaster (large metorite, large volcano, nuclear war), that food source would be threatened by diminished sunlight. Insects such as termites could digest the cellulose contained in plants and become a food source for humans until the skies cleared.

Back on the subject, George Washington Carver actually came up with a number of meat substitutes made from peanuts. What if we started eating those instead of insects?

No it's not unrealistic to believe that there could be other intelligent life in the universe. However it would be unrealistic to assume there are only two, us and them.

Intelligent species could be aware of empathy even though they may lack this emotion. They could also be aware of strength in numbers. Intelligence means moving past instinct and using rational analysis. A single instinctive predator is no match for an intelligent rational collective.

The solution is to stop CAFOs and switch to pasture based livestock. We raise animals on pasture that is not suitable for cropping. We turn sunlight into high quality protein and lipids. Next, buy from your local farms. Can't because you're in the city? Well, that is part of the problem. Get out of the cities.

A local galactic community of intelligent beings. The chances of them being a benevolent cooperating community are slim. They would have contacted us by now. It is far more likely that any intelligence that survives to achieve interstellar travel will be anything but benevolent. A hive intelligence would be likely to survive and they would be motivated by self-interest. A predator species like us is unlikely to survive to achieve interstellar travel and we wouldn't be benevolent if we did either. We are motivated by self-interest both as individuals and a species.

A collective of insects behaves like a single instinctive organism. The 5 year old is part of a larger community (family), who is intelligent enough to create a magnifying glass among other things.
Instinctive species don't have laws. Laws can and often do stand in the way of our own self-interests. The reason we haven't been contacted is probably because aliens are intelligent. They realize that, quite often, humans still rely on instincts, and that makes us dangerous and predatory.
