Cinque Terre Plastic Water Bottle Ban

The five coastal villages that comprise Cinque Terre, in Italy, banned plastic water bottles in 2010 amid concerns that the area--a national park--was being literally buried in garbage by the hundreds of thousands of hikers and tourists visiting each year and leaving behind their plastic water bottles. Local experts put the garbage toll at about 2 million plastic bottles per year.

Now, visitors are asked to pay one euro at the park's entry for reusable flasks that can be filled up at any of a number of new public water fountains.
