Not many people know that every growth of banana tree (technically called "follower") produces only one banana bunch during its life.

In fact, once the bunch is harvested it must be cut and left to rot, in order to allow the next growth to mature and produce another bunch within the next 6 months.

During this rotting procedure, it releases a lot of Co2-e in the air in the form of methane gas, thus becoming a big pollution factor.
