After "I'm Yours" remained at the Billboard Hot 100 chart for a record 76 weeks ending in October 2009 (peaking at number 6), the singer/songwriter headed to the Gulf of Mexico in the summer of 2010 to help with efforts to clean the Deepwater Horizon oil spill.

Later, Mraz was in Antarctica, spending time with Al Gore and learning about climate change aboard the National Geographic Explorer.

During his activist outings, Mraz wrote and recorded his fourth album, Love Is a Four Letter Word, with producer Joe Chiccarelli.
