I am engaged in a conversation with a woman who blogs on the topic of "being green" for a fairly large newspaper's website. She is open to learning more about the science underlying the green movement and has asked me to point her towards resources that non-scientists can use to learn more about the health/environmental/etc. effects of consumer products' individual ingredients. Unfortunately, this is not my area of expertise; the resources I'm aware of are best suited for a more technical audience. Can anyone suggest some scientifically sound, well-sourced, easy-to-understand information on this topic? I believe that she's particularly interested in a primer on the subject and in a "one-stop-shop" (besides Wikipedia) where she and her readers could search for reliable information about the effects of given consumer product ingredient.
Thanks in advance for any help you can provide.
