Plastic waste is not just something we step over on the street or on a beach. It is a material that has quietly rewritten ecosystems, economics, and even human biology and once you notice that, it becomes impossible to treat something like “marine litter” as a simple tidy-up job.

We sit down with Sedat Gündogdu, a marine biologist and environmental researcher whose work focuses on plastic and microplastic pollution, plastic waste trade, and the social and political forces that keep plastic production growing. Together we unpack the idea of the Plastocene, a grounded way to understand the Anthropocene through the one material that has become a permanent global signature. We follow the thread back through industrial growth and wartime scale-up, then forward into daily life where plastic shows up in far more than bags and bottles.

We talk about why plastic recycling so often functions as greenwashing, how it shifts responsibility from producers to consumers, and why that comforting story still works. Sedat also breaks down the main routes of exposure to microplastics and chemical additives through food, drinking water, air, and even medical settings and why systemic regulation matters more than perfect personal habits.

Listen in, and share with someone who still trusts the recycling myth.
