Sonic styrofoam cups and plastic straws harmful to human health and environment

My brother and I love Sonic slushes and have been visiting Sonics at least twice a week for several years. However, we have recently learned that the styrofoam cups the company uses aren't biodegradable and contain carcinogenic benzene, and the plastic straws used are polluting the world's oceans at an alarming rate. As a result, we will reluctantly forego our twice-weekly "fixes" of the company's delicious slushes until it starts serving them in paper cups like 7-Eleven, and converts to paper straws as McDonald's and Starbucks are doing. We urge others who care about human health and the environment to consider a boycott as well, and to sign this petition.
