I was fascinated by everyone's presentations and active discussions. It makes me proud and excited to be among such great, creative minds. We are surely one bright generation :)
My favorite proposals were Jacob's "Plantronics" and Sarah's "ECOfacts." It is already known that the Earth is a conductor of electricity and we use the ground to place power plants, electric generators for our homes, and multiple other electronic devices. But, it never occurred to me to utilize plants' own natural networking system within the soil instead of wire connections. I didn't even think about the reference to Avatar, where the trees were used for energy. I found an article about a replica of Avatar's 'Tree of Souls' that was built in London's Hyde Park. This tree (picture below) is made up of a metal structure with one root that acted as an electric cable to power the whole tree and it's glowing fiber optic cables. The article said that the tree provided it's own WiFi network so visitors could log into their website and play music to change the tree's colors. Although this tree was man made, we could possible use living plants to do the same thing - transmit electricity.

"Ecofacts" was such an innovative proposal. Sarah's project design was also well thought out and user friendly. I believe that, in theory, this idea could do wonders for our society and environment. However, like many people addressed in class, the meat industry and the government has so much authority over food production that it would be a challenge to implement this idea. Also, food production is a large multi-step process and it would be hard to track an accurate usage of water, carbon dioxide, land usage, etc. I am not sure if farmers/producers even measure these usages. I feel like current ways of being 'green' is by changing ways food is produced. I found an article on this Meat Plant Waste System that saves carbon dioxide emission equal to 2,700 cars! The biotechnology uses anaerobic bacteria to digest around 80% of the organic matter in waste water and produce green energy.
I completely agree with Sarah's statement that "change begins with education" and Ecofacts is a great way to make people more aware of what they are consuming. Other methods of providing education is through sites such as Food Production Daily (http://www.foodproductiondaily.com/Trends/Going-green).
