My work is base on questions: The first one is time (past - present - future), the second one is on marking (Drawing - writing - printing etc...). Relate to the show (Earth Matters) I can say mouvements (humain activities):
walking, moving by cars ,trains, boats, airlines etc..., building houses, roads, bridges etc... All are marking printing. And the question is what is the impact of all on earth is it negatif or positif ?
