Buggin' Out: Urban Bug Farming for the Future
I think this idea is interesting. If we just consider about the nutrition if people eat insect, it is a very fantastic and useful idea to provide a valid food source strategy. But I have a question here, can everyone accept eat insect? Personally, even though I know there are a lot of benefit to eat some insects which contain various nutrition and amino acid, I don't want to eat them unless there are no other food can eat. I think in order to absorb the nutrition from the insect, we can analysis the specific content of them and use some other technology to mimic the content in a real food way such as " food drink". We can also feed chicken, pig or cattle by insect, and then we may absorb all nutrition from meat and insect when we eat meat. But there also have some problems.First, chicken or pig can digest the insect, and the nutrition may transfer into other kind of materials in their bodies. When people eat meat, we may not absrob the nutrition which we want to get. Secondly, if we foster more chicken and pig, the biodiversity may be destoried, because people change the natural food of animals, and they may have some unpredictable mutation in future. We need do more research about this topic.

Can urban beehives increase food production?
I think to develop an urban beekeeping industry is a good idea, and it can be achieved easily. But I think it is not enough to keep all the bees healthy. I read your introduction and I find you said the main reason which cause the CCD is a virus named Israeli acute paralysis virus. I think the way which people can solve this problem is decrease the number of this virus. I think eradicate the virus is not a good idea, because if the virus die out, there may cause some other issue. If one of species desapear, there will be a chain reaction which is caused by biodiversity disorder. I also have a question here, is the beehives so important for all the food production? I think it dosen't have so much power in all the food production.

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?
Belo Monte Dam project is actually the project which will provide the enough electric power to brazilians, so it is benefit for the society. But for the nature and environment, it will bring a huge harm, because this project will submerge most part of Amazonas tropical rainforest, and damage tne local entironment. What's more, at least 30 thousands aboriginal will be forced to move. Some people who are against this project show more probale result if the project is carried out. As people know, leaves grab and absorb a lot of carbon elements, once they are submerge in the water, these leaves will produce huge amount of methane by methanogens without oxygen. Methane will casue global warming, and it will be more harmfulthan carbon dioxide. Even though there are some harmful to the environment of this project, we can't deny that this project will solve the electric power problem of brazillians. What's more, this project have an important water resource regulatory function, and it will transfer the damage of flood period to the resource of drought period. So this project will make the electric source like a renewable resource. Personally, I think the benefit of this project is more than the harmful, and just for now, people don't have a better idea than this project.

Purell now, Bacteri-ell later?
There are about 200 hundred kinds of baterias which will contact human body, some of them stay on our skin for a long time like living in our skin, some of them just "visit" our skin occasionally. Actually, the bateria is the part of our bodies, if there is no bacteria exist, human can't live. Some bacteria on our skin will cause disease, but some of them are very benifit for human being. Staphylococcus, streptococcus, propionibacterium and corynebacterium are the four main bacteria on human's skin. I'll talk about the staphylococcus a little bit. Only if this bacteria go into the inner memberane of human's skin, it will make the inflammentory reaction and damage our bodies. Otherwise, it won't hurt people. Few years later, some researchers found something new. The metabolite of staphylococcus will inhibit the inflammentory reaction and it will be controlled by the keratinocytes of the staphylococcal lipoteichoic acid. If we over wash our hands by using the Purell, the metabolite of the staphylococcus will be wash out, which is not good for human. But we need to explore more and more in this area.

What form of renewable energy has or will have the lowest impact on biodiversity?
The energy problem is really serious in the world now. Many people work on this problem and they want to find some new resources which are renewable. For example, the solar energy geothermal energy, light energy and biofuel are used widely in these years. All of these energy are renewable and less pollution. But if we consider about the effect of new energy resource on the biodiversity, we may need to do it more careful. For the biofuel, it is a very green and new energy resource in the world. Biofuel always come from the plants, which is very easy to plant. To use the biofuel, people need to plant many energy plants, but these plants will grab the land, energy and resource from the native plants. What's more, the human effect will cause the energy plants more easier to survive than the native plants. After several evolutions, the native plants may die out which will affect the biodiversity. Then the overload energy plants will destroy the land and make a non-renewable lose of biodiversity.
