Sea and beaches in Poland are highly polluted. People throw rubbish into the water. They do not realize how much harm the environment and small animals living in water. They are rubbish, such as cartons, boxes, cans, bottles, bags and many other equally dangerous for the environment rubbish. If you do not want to sea and beaches turned into a huge garbage dump is a waste to throw out a specially designed containers to.
Wydaje mi się że tak to powinno brzmieć :)
