pros: reusable plastic is good or knee or hip replacement, good for storage, good for furniture, it is lightweight and easily accessible. straws wise, they are easier to drink out of than a paper straw.plastic can be flexible as well. it doesn't really mould or decompose as wood does cons: they ruin the sea and beaches, they kill land and sea animals. they do not decompose,so a lot can still be lying around after littered for hundreds of years. it can break easily and for an example, if you use, let's say an oasis bottle for too long bits of plastic start to peel away inside,which is hazardous because we can drink it. if it is littered it can break into small pieces and animals can mistake it for food. how we think it looks what actually happens
