The straw stuff is supposed to be about the size of the straw and their propensity to get into the environment and hurt animals. Cups don’t have the same effect. (That said, my understanding is the straw research is based on a 5th grade science project and most of the straws that reach the environment are from third world countries that don’t have good landfills or waste disposal systems...)
