I think Lilienfield sums up human foibles/psychology pretty well (in terms of why people on't conserve more), but the book is dated and we do most of the stuff in it. Still, there might be something to be gleaned from this book for some people. His mind/heart is in the right place, I think, (except the part about eating more processed food, because the preparers waste less. (If one composts as he suggests, then it hardly seems to me that we waste the food, but we do have to be careful about spoilage.))
