And I don't mean responsible in the "don't drink and drive" sense. That goes without saying. I mean in the green sense. I attended a great event today and, like most events, parties, etc., there was no recycling.
The use of paper plates and plastic cups is, understandably, a necessity for a huge event. I've done my fair share of entertaining. It's nearly impossible to keep up with dishes for a small event, let alone a large scale event, without the benefit of paid staff. Recycling, on the other hand, requires nothing more than a couple extra trash cans and the desire to make the event a little greener.
So next time you host something, be kind and provide your guests with a recycling option. It's a way to party more responsibly.
