Sometimes small actions you take can make a difference. Let's start with your coffee cup. If it's paper or foam, it's going to join billions of other cups that are discarded and dumped in landfills every year. (And don't get us started on those cardboard sleeves.)
Simply put: Disposal here means destructive. Creating disposable cups is a drain on resources and energy, and discarding them means filling our landfills and further polluting the atmosphere with methane—making climate change an even scarier prospect.
So, enough already. Get a reusable cup and take it with you from home to coffee shop to office—or wherever your day takes you. (And if you already have one, remember to use it!)
