I was scouting the sale bins at Hastings in Brownwood, TX when I was visiting there and found a neat book, Easy Green Living, by Renee Loux. You might want to check out the sale bins here--I recommend it.
The book looks at a lot of household items and discusses the environmental impact and suggests alternatives. It includes cleaning products, appliances, cookware, personal hygiene and beauty products. She also discusses labeling and what many labeling terms mean (in some cases, not much.)
The book is listed for $10 on Amazon, but I picked up at Hastings for $7.99.
