There it can reach levels that are toxic to aquatic life.
16. My first requirement for the company would be that all the sweaters are made themselves, this is vary important because without the sweaters there be no operation there for no company. The next job, is boxing all the sweaters, this part is also vary important because if no one boxes the sweater no one will get the sweaters, another reason is so people world wide can get the sweaters without having to travel across the world for it.
