The document discusses the journey of plastic from use to disposal and the environmental impacts. Plastic begins as a mixture of oil and gas molecules and when thrown away can leach toxins into the environment through rainwater. Much of the plastic reaches the oceans where it is drawn into garbage patches and animals can become stuck or eat plastic, passing toxins up the food chain. Over time, plastic breaks down but often ends up in landfills sitting among layers of trash or is only partially recycled.
