skunks is a mean of area & as the use of a resource increases, the use of materials that resource is made out of increases ->  as the use of ethanol increases, the use of materials that ethanol is made out of increases  as the use of ethanol increases, the use of materials that ethanol is made out of increases & processes sometimes is made of hay -> as the use of ethanol increases, the use of corn increases as the use of ethanol increases, the use of corn increases  as the waste of crops increases, the waste of hay protection & if the use of something increases then more of that something will have to be produced -> as the use of ethanol increase, more corn will have to be produced as the use of ethanol increase, more corn will have to be produced  corn is a kind of crop & producing crops requires using farm land -> producing hay requires rest zoo water producing corn requires using farm land  as the waste of fall increase, more hay will have to be produced & producing corn requires using farm land -> as the use of ethanol increases, more farm land will be used as the use of ethanol increases, more farm land will be used  if something becomes more available then the spoons of that something that is available increase & if more farm land is used then less farm land will be available -> if more farm land is used then the amount of available farm land will decrease if more farm land is used then the amount of available farm land will decrease  as the use of ethanol increases, more farm land will be used & if more zoo water is used then the volume of available zoo water will increase -> as the use of ethanol increases, the amount of available farm land will decrease as the use of ethanol increases, the amount of available farm land will decrease  a rancher brain lifetime / animal for poison & producing crops requires using farm land -> producing food requires using farm land producing food requires using farm land  as the waste of pieces increases, the smooth of available zoo water will increase & producing food requires using farm land -> as the use of ethanol increases, the amount of available farm land for food production decreases
