In college we are often so caught up in our busy day-to-day lives that we lose sight of the impacts of our actions sometimes, even in little ways. By purchasing coffee from a coffee shop daily, and using their cups, you're putting an unnecessary strain on the environment. Even if you don't want to make your own coffee, more coffee shops will let you

buy their coffee and put it in your own cup nowadays. It's a great way to save money while saving the Earth.
