Buggin' Out: Urban Bug Farming for the Future
P.S : I found "canned Bundaeggi" in the one of local Asian markets in Eugene!!! Look like this----->http://koreanfoodcrime.files.wordpress.com/2009/12/bundaegi1.jpg If you want, I will buy one can, and try it in our class tomorrow as a novel experiment ;-)

Buggin' Out: Urban Bug Farming for the Future
Theoretically, eating insects as protein source would be affordable idea because it has better protein ingredient contained and less natural sources required to grow. However, there are several application issues. Many people oppose to eat insects because of the nice exoskeleton looking. Let me tell my some personal experiences. I have traveled a lot and occasionally I have chances to eat insects that are locally considered famous and delicious cousins. Well, what I thought was there was a reason why they liked it so let’s try. One of them was Stag beetle larvae deep fried. It just tasted like “Cream cheeeese puff!!!” For sure, sometimes, it tasted weird such as Bundaeggi (silkworm chrysalis) in the Korea. For me, appearance-wise, it seems really similar to shrimp or crab. “Think it is just a land shrimp or crab and eat, it would be not big matter.” But the real issue, that is under-assumed, is a distinctive odor. It is so special and strong enough to be hard to hide under seasonings unless buried into seasonings for a while. In order to spread such the consumption insects as food, I think it is required to remove such special odor. You may think that “then, why don’t we just eat non-special odor insects. Well, it would be good idea. It is easy to grow in urban area because it needs less area than a cow. However, it may cause ecological issues. We have heard about foreign species invasion and they have destroyed local ecosystem. Many of them are once introduced as food or other reasons like pet. If they are ensured in closed facilities, it would be okay but they escaped and spread out. Nutria, snakehead are the good example. They have imported as food sources, but escaped and spread out in local nature. Then my question is that “are we sure that such the edible insects won’t harm local ecosystem when they are escaped?” insects are smaller than conventional farm animals which mean it is much higher chances to escape from farms.

Can urban beehives increase food production?
Well, I have lived in Eugene for 4 yrs. Good thing is that they rarely use pesticide because it is their garden where their kids and pets are playing... Maybe, if we provide a small lecture in the elementary or high schools to kids, it would be more effective. It is because kids easily deliver message from teachers to parents and more effectively spread message than give a lecture to the adults.

Can urban beehives increase food production?
I think it depends on the size and type of cities. First of all, a beehive needs certain amount of food source (flower) within area because their area activity is limited.(they cannot fly all the way to the outside of a city) In metropolitan like in the east coast, the food source is limited and then more bees are possibly attracted by the artificial sweetness that human has such as perfume, food and soft drinks. In this cases, the chance of contact between human and bee increases and correlated health problems also increases. However, a city like Eugene is possible to share a habitat with bees. These cities have a good food sources in parks and gardens area so bees have available food sources. Even though there will be some health issues, we can give a short education lecture or video how to avoid bee's stinger and provides some emergency antibody for bee's sting to the publics.

Will the Belo Monte Dam project on the Amazon River cause more harm to the environment or will it be a good source of energy for Brazil?
Usually, dam has multiple purposes such as storing water, generating energy, and preventing flood. However, this dam does not seem to have many other purposes but more likely only generating energy. In fact, the efficiency of electricity generation by dam is significantly low than other power source like thermal or nuclear. South Korea has built 15 multipurpose dam, but it only generates 1.7% total demand of electricity(In contrast, 17 thermal power plants generate more than 40% of electricity.) According to one government report in the South Korea, Building a dam is actually not a profit-making in long term perspective in terms of losing tourism and other possible uses of the nature. I think the better way is to build nuclear power plant(Well, green power generation like wind sounds wonderful, but the efficiency is not that good because of instability by seasonal and daily weather effects) by international fund + their own fund and conduct a research project how to develop this area to make better profit by tourism and other possible uses. Do not just say them " no dam, we save the amazon and indigenous people's homeland." It cannot convince the Brazil government.

Cats pose a serious threat to biodiversity: Why do we accept it? What should be done?
I think overall Morgan's idea seems right; however, his way to address the issue was radical, especially, in terms of dealing with one of favorite pets for human being. First of all, people are not ecologists or biologists. Statistics and data do not open our minds and convince the importance of cat control. Number is just a number. For this issue, I think we need more political approach than science. As the first step, to make a documentary like the National Geography, or even TED Talk seems a good idea to convince people why we need a cat control for preservation wildlife. Such the visual information is, sometimes, more effective than a well written article. The next step will be to start indirect and passive controls. Legislation of registration and neutering of domestic cat is a good example. It does not really kill or actively remove cat by human hands, but it prevents that more escaped cats flow in the wild life system. Especially, Registration of cat with small under skin-implanted magnetic chip is important for next action to give strong responsibilities to cat holders. Based on registration of cats, we can give fines when finding cat holders with unneutered cats or holders who do not care cats properly. Additionally, taxation for cat holders is also good idea. This tax can be used for restoring destroyed wild life by cat and neutering street cats. Meanwhile, we can capture street cats and neuter them and send the humane society or adopt cats to people who want. This action is very important because at least, we have a good excuse that “we try to save cats by adoptions, but you guys do not want. Soooo, there is no option..”

Purell now, Bacteri-ell later?
I think in cetain level of future bacteri-ell help to strengthen or rebuild human micro biome, but the replacement may not happen. Because a significant level of microbes are encoded by the individual human DNA and there are some deviation among individual human being. It means my micro-biome is not same as yours. Then, if someone introduce a "generic bacteri-ell" to a individual, it may cause to destory his or her own micro-biome which would be worse than weaken biome.

Well, it is a interesting point that healthy microbes help to build stronger immune system. I agree that. But Not only healthy micorbes but also harmed microbes halp to strengthen human immune system by exposure. Human T cells have a interesting ability that, sometimes, reconbine past memories of infections and form new antigens against new infection. I assume that in countries sides, there is more chances to expose minor harm and useful micorbes of which leads more learning chances. Thus, human immune system of countries people have more "life long wisdom" in their hand.
