Worksheet 9

Our ecological footprint

We draw a footpring steping on one paper with our foot. Today we consult in one web ( doing one test) wich is our ecological footprint. The web gives the result in "dam2" and we translate this in cm2. Then we mesure the length and width of our footprint and multiply that to know the area. Finaly we divide the ecological footprint by the area of foot and we get the number of footprints that we waste in one day.Every day I print 5.138.888,88 footprints. Do you think that this is a lot? I think the same.if you want to do the same and know haw much footprints do yo print a day click here!
