=media type="custom" key="21590904"= The football is made of blatter,cow high. cow high is from cows. You get blatter from rubber trees. You get leather from cow skin. The environmental consequences are when they are making the foot balls the smoke is poluting the air. media type="custom" key="21591068" When the cow high is turned into leather you can't turn it back. When the sap from the leather tree gets took to the factory. They turn it into blatter. They will keep throughing the footballs out. Then if they keep throughing them out there will be a big pile of footballs. media type="custom" key="21606228" The football is took by a truckk to the sport store. The environmental consequences are the truck will polute the air. media type="custom" key="21606276" The football will last for about two years media type="custom" key="21606326" What you do with the football is you through it in the dump. The leather on the football does breack down but the rubber does not. The air sneaks out. The football can't be recycled because some of the resources are natural. The environmental consequences are that when all the leather breaks down but the rubber will keep building up in piles.

I learned lot's of thing's in energy tranformation. one of the thing's that I learned about is the rollback can.The tranformation in the rollback can
