Back in March, as SFist first reported, thousands of red balloons were released into the air from Yerba Buena Gardens, a stunt that was part of game release launch for Home Front. Although the balloons were allegedly made from a 100% organic product and are 100% biodegradable, the San Francisco Bay Regional Water Quality Control Board "has fined national marketing company TrashTalkFCM $7,000 for [the] promotional event
that resulted in hundreds of red, latex balloons falling into San Francisco Bay."
Many of the balloons ended up in the Bay, endangering wildlife. See for yourself.
