After watching Grand Designs last week, it featured a ""sealed"" house, I got to wondering, is there or has there ever been research into the effects of controlling CO2 emissions, footprints etc.
It strikes me that with a house that is sealed from the elements etc we, as a specie, will get used to living in a sterile environment which in turn may result in lower body tolerances to everything.
Does anyone have any news on any research for this or am I just going off into a world of my own?
