Black gold

Something very interesting is taking place in the world these last months. We hear day after day after day (I even sometimes switch off the radio at the news time) that € is too expensive compared to $, political climate is uncertain, States want to establish a common life but in the end only act for their own purpose ... and oil. Oil prices are driving mad and I hear here and then professionals (truck drivers, fishermen, ...) striking because they can't pay anymore to tank their work tool, even the french army on sea canceled maneuvers because of this situation. It is a certain fact that earth ressources are not expendable and sooner or later before the sun will hit our planet man will have to find other solutions. Can we live without black gold ? Try.
