In New York City the paper cup is a hallmark of a particular case of urbanism: the dwellers & commuters are constantly drinking while on the go. Each block generates almost as many paper cups per day as the numbers of the people living on it (according to my crude reasoning). But then paper cups go a long way. The trash can is just the first journey along many for this paper cup to sustainably reincarnate itself in another form.
The metro-governance of the City of New York is busy untying big development knots like those going on at Ground Zero or at the yards of Hell's Kitchen. And it's busy selling porcelain cups that look exactly like their paper counterparts but that are more friendly to the waste management system. "I Am Not A Paper Cup" is officially brought to you by the Official Store of the City of New York. I say buy it and spare some more trees from your Caffeine rush.
