Several hours after dark in a quiet Caribbean neighbourhood, a cluster of environmental activists gather on plastic chairs between a mango tree and a courtyard wall emblazoned with the words “Colombia, respira!” (Breathe, Colombia).
So many people have turned up that some have to stand. That is because tonight’s speaker is Susana Muhamad, one of the most admired socio-environmental campaigners in the world, and this is a moment of profound historical significance.
