In our first episode of this special three-part series, we explore what plastic actually is and why it's become such a massive environmental problem. From the molecular structure of polymers to the devastating impacts on wildlife and human health, this episode lays the scientific foundation for understanding the plastic crisis. We'll examine the chemistry behind different types of plastic, track their environmental footprints, and delve into the emerging research on microplastics in our food, water, and even our bodies. By the end of this episode, you'll understand why this miracle material has become one of our most pressing environmental challenges.
