keep diging? / Graphic design

Recently the global warming has being the most important and tricky issue.Many scientists are trying to find out the more quickly and best way to make up for the global crisis.While scientists work hard on it,our life still going on as if nothing is happening that huge amount of exhaust emission in this poster.I used the autocar’s speedometer to highlight the golobal warming issue.
Driving faster that the oil also consumpt very fast.
If each person drive car everyday,the realse auto emission’s is very huge
I'd like to remind people by the poster to show the connection with auto emission’s and the earth.
