Tar sands 175 billion barrels proven recoverablereserves.

(US used about 6.3 billion barrels in 2008)

Significant environmentalimpacts?

Carbon dioxide is removed from the surface oceans naturally by photosynthesis;some amount of the fixed carbon is preserved as sediment – perhaps to becomepart of the intermediate carbon cycle.

Can this amount be increased by oceansurface fertilization using iron, etc?

Can carbon dioxide liquid be released intothe deep ocean by direct injection?
