Biofuels (page 330)

The picture was taken at a gas station, and we can see on the right,  a fuel pomp that distributes the liquid, and on the left, and advertisement that promotes the use of biofuels, and indicate the type and percentage of gasoline that people are going to use.

This picture, is a funny representation of biofuels. In the middle there are a human hand holding a pod corn that simulate a fuel pomp. Probably, this indicates to the spectator the possibility to use biofuel as an easy and cheap solution to not contaminate more the planet.
