Interview with MOD MTV Brazil:

As visitors breathe amongst the trees, 21% sonifies our interdependence with the plant life around us.

You are colluding with the plant life around you. Trees absorb the noxious gasses we expel,
transforming them into energy as they excrete oxygen, in turn supporting all aerobic life.
21% sonifies this exchange. Visitors use their communal breath to influence the sound collage
and maintain a balance with the plant life in their midst.
