What are the health benefits to one/all of us if we reduce the particulate matter in urban air?
How can we measurably improve air quality inexpensively and immediately?
The Drawing in Air Clinical Trial responds to these questions by using the greenhouse effect to address the greenhouse effect; Sequestering where it counts while measuring what we can sequester as a visible participatory response to the failure of negotiations in a particular location. It is an inexpensive, scalable, participatory method to improve urban air quality: create a passive solar chimney to capture black carbon and create a captured-carbon-pencil, the length of the which corresponds to the amount of grime pulled out of the air.
