Bioplastics are often marketed as an eco-friendly alternative to traditional plastics. However, this "green" image can be misleading. Many bioplastics are not compostable and cause similar environmental harm, particularly in oceans, as their petroleum-based counterparts.

It's crucial to recognize that not all bioplastics offer a sustainable solution. To truly combat plastic pollution, we must move beyond all forms of plastic.
