Showcasing environmental degradation by delving into the lives of the local community is a filmmaking style practiced by Mumbai-based filmmaker Pooja Das Sarkar. Her film 'Sagarputra: Offspring of the Sea' is based on the life of the Kodi community who have been fishing in Thane creek for almost 500 years now. The toxic, plastic-filled water of the sea and being locked in by the government's infrastructure projects, on all sides, these fisherfolk are gradually moving away from the livelihood of fishing. She chooses to include a lot of community voices in the film, rather than experts. The only experts in her film are the people from the community itself.
