Grow Your Own Fresh Air
Interesting TED talk on houseplants and office plants allowing occupants to grow fresh air. This links into the growing concept of biology and the built environment. This is the concept of providing a cleaner living/working environment by managing the biology of the surrounding environment within the HVAC system rather than forcing the system into sanitation. When forcing the system into sanitation it creates ideal breeding grounds for the types of bacteria that humans are susceptible to. By managing and purposefully allowing the bacteria that do not harm humans, the bad ones have to compete to survive and therefore are not nearly as successful at surviving host to host transmission. Interesting stuff, much more to come from other sources I believe.
