Plastics are everywhere – from cell phones to soda bottles, to trash on the beach and in our oceans. Yet while our lives are dominated by plastic, plastics and their environmental impacts are still largely misunderstood by many people. This three part series explores plastics—from their creation to what happens once they go in your trash can or recycling bin. Part I begins by answering the first big question: “What are plastics?!”
While some plastics are naturally found in the environment, the majority are man-made. Man-made plastics are created when individual carbon molecules are chemically bonded together. These carbon molecules are typically extracted from oil, a non-renewable resource, but more eco-friendly alternatives use carbon derived from natural materials like corn oil. Individual carbon molecules are combined to create compounds like styrene, ethylene and formaldehyde.
