Although Californians are pretty good about recycling plastic bottles, the caps often undergo a different fate. Due to their small size, they are easily discarded and overlooked. These caps then enter our waterways and negatively impact marine life. In fact, bottle caps are one of the most commonly found items found on beaches during cleanups in California. This is super concerning because marine animals could mistake them for food and it could cause blockages and death. Aditionally, these caps can break down into microplastics which are then ingested by marine animals and passed up the food web. This can seriously harm these organisms and humans too if they ingest them.
