Where did the recycling symbol come from?

With its circle formed of three green arrows, the Möbius strip has been the universal logo of recyclable materials (but not necessarily recycled materials) since 1970.
It owes its name to the mathematician August Ferdinand Möbius, who in 1858 was the first to describe a two-dimensional object with a single face. The schematic version was chosen as the symbol of recycling on the first Earth Day, an event created by Wisconsin senator Gaylord Nelson to raise global awareness of the environmental cause.
