TurnbullJonathon VtP Annotation: What does this visualization (including caption) say about toxics?

The image and caption both comment on the flowing and cyclical nature of toxics - both materially and culturally. Materially, because the pollution is carried by a river. Culturally, because the public discourse around river pollution comes back with the seasons. Perhaps this could be highlighted a bit more in the caption.The presence of the worker in the river also draws attention to the labour involved in dealing with toxics. The fact that it is an algal bloom as well - the presence of life - also shows how toxics are a more-than-human issue. I would like to hear more about the religous element involved in this work, too.
