Paper. Paper is bio degradable, when it gets wet it will sink into the ground, while plastic will take years to break down. Paper is harmless in environments like the the ocean unlike plastic which can kill animals. It can be wrapped around their throughts, big solid pieces could choke them or hurt them if swallowed too. Someone might argue that plastic has more uses, that’s true... however that doesn’t make it better for our environment. Therefore paper is better for the environment. And you should always pick up any plastic you outside!!!
