Bio-degradable Bags

Well after surfing the net for a while, I have found out that bio-degradable bags are not what they seem to be. It seems that they need oxygen to degrade and in the landfill that is taken out of the equation since dirt is covered over them. This then lends me to believe that the enviromentalist have messed up again. Does any one remember the paper bag issue? The paper bag could be used for arts and crafts, book protectors, recyclable, and decomposed in a compost pile like nothing else could. We are definately coming full circle I believe, the question is, can the people of the world be made to believe that paper is the best answer? Paper is recyclable.
