Q. Dear Umbra,

My peers and I are working to better our campus. We’re looking into the most sustainable option for drinks on campus. What’s better for our school to buy and sell: glass bottles, plastic bottles, or aluminum cans? Ideally, we would forgo all these options and use fountain dispensers and reusable cups, but financially I guess that is not an option.

A. Dearest Tessa,

How I love to hear from young people working to better things. Your natural idealism is one thing, but paired with some roll-up-our-sleeves-and-get-to-it-iveness, you are practically unstoppable. It fills me with hope for this new year, which will likely require all the idealistic hard work we can throw at it.
