en Altadefinizione. Are we becoming Plastic People? Our ground-breaking feature documentary investigates our addiction to plastic and the growing threat of microplastics on human health. Almost every bit of plastic ever made ends up ground down into "microplastics". These microscopic particles drift in the air, float in the water and sit in the soil. And now, leading scientists are finding them in our bodies: organs, blood, brain tissue and even the placentas of new mothers. What is the impact of these invisible invaders on our health? Ziya Tong, author and science journalist, makes it personal by visiting leading scientists and undergoing experiments in her home, on her food, and on her body.
