I was just listening to 'Hack' on Triple J and they were reporting on a small NSW town, Bundanoon, who are planning to ban bottled water from their town. Go Bandanoon!
Filtered water fountains will be installed along the main street and residents will use their own re-usable bottles to keep hydrated.
Hmmm hopefully Sydney catches up soon. These bottles from Sigg (available here) are sooo much cooler than plastic bottles anyway!
