Cities like San Francisco and Los Angeles have made new recently for prohibiting the use of city money to buy bottled water.
Others cities are considering similar moves.
They're spurred in part by growing concerns over waste.
According to the Container Recycling Institute, we Americans throw away more than 60 million plastic water bottles each day.
And the vast majority wind up in landfills.
Chicago filmmaker Bill Kirkos say that's just the tip of the iceberg.
Kirkos is the director and producer of the new documentary Trashed.
It opens tonight at the Music Box Theatre in Chicago.
Kirkos says our throw away culture is creating big problems for the environment – and for global warming.
And he says when it comes to trash, we're generating a lot of it.
