B.o.B celebrates Earth Day with a brand new mixtape. After making waves with his theory that the world is flat, Bobby Ray delivers E.A.R.T.H: Educational Avatar Reality Training Habitat.

The project features more of the ATLien’s controversial views on the world. “Under the Dome,” for instance, kicks the project off with raps about modified beef, chem trails, fluoride water, and acid rain water.

The 10-track project, which follows January’s FIRE: False Idols Ruined Egos, outlines more of his thoughts and what he feels is being hidden from others. “Fkn’ Science Bro,” for instance, has him questioning evolution and dinosaurs.
