if i can’t alter the biology of organism, I can imagine how they could be changed. its perhaps a bit naive to envision ecological indicators as tuning themselves to the human species in simplest ways (like changing colour or smell to meet the desires of a passer by) but then again, its bit like Olafur Eliasson in his Green River series: he dyed parts of rivers with uranine, a non-toxic water-soluble dye used to test ocean currents, to make passers-by aware of their surroundings.
Making humans aware of moss. If moss is usually only apparent when air quality is good (and therefore going fairly unnoticed) what if a type of moss appeared in areas of high toxicity and in synthetic colour? pink seems one of the least natural colours ever (funny how green is often associated with toxicity and poison…)

pink (or rather red…) is the colour cabbage die goes in acid conditions. perhaps the colour pink alludes to a toxic environment. an intervention could be applying fake pink moss to areas in london of the worst pollution
