One ecosystem mentioned in the film was the one of oysters -which actually is also man-made, as it is an oyster-farm - but I think it becomes very clear in the film that it became more difficult to the oyster-farmers to cultivate the oysters through the 6th Naphtha petrochemical complex. The farmers talk about mud and other new circumstances that kill the larvae of the oysters. In this context, this is also affecting the socio-sphere, and the impact on the eco-sphere is not so much highlighted in the film, but I think it would be interesting to look further in this point.
