Coffee Cups Are Omnipresent

You can't ignore something as big as a coffee cup, especially in comparison to flimsy pieces of plastic. There's no particular season or time period that people use or don't use coffee cups; they're just always around. People drink coffee, or something, in the winter, fall, spring, and summer. Even people that don't drink coffee generally drink something out of a coffee cup. They're perfect for holding milk to dunk cookies into, for example. Many that don't drink coffee still drink other hot beverages, and they'll gravitate toward using coffee cups because of the handle that doesn't get hot. Calenders will last four seasons, but that's it. After those initial four seasons, they're landfill or recycling center bound. Plastic key rings and such are used mainly because they're cheap, and cheap stuff breaks quickly and easily.
