The QS movement is shedding light on the age old debate of nature versus nurture. Just how much does our environment affect our health? While it's debated, there's no doubt it has an effect as recent studies demonstrate: "research suggests that five of the six problems that pediatricians spend most of their time on (childhood cancers, asthma, developmental delays, obesity, and diabetes) are significantly correlated to environmental factors." So it's only logical that QS tools focused on the environment should emerge. Like the collaboration between RISD and Public Laboratory that created a Roomba that can visualize the air quality of a room.
Or the water pressure sensors of Edison Thomaz. His sensors show how water is used in the home and provide inferred behavioral data of the inhabitants.
Definitely expect to see more QS products focused on our environments.
