I can TOTALLY relate! I periodically go through a similar drowning in information, feeling completely hopeless! In a way, I think you have to choose your battles, or it does get too overwhelming & discouraging. I've tried to concentrate on things that we use the most - food, body products, and cleaning products. For those (and any other issues), I try to focus on the issues that are most alarming or have the most scientific support for concern. I like EWG and www.healthychild.org. I also like the SkinDeep website to read up on specific chemicals of concern.
Here's what I've been doing:
Organic is definitely more expensive, but shopping HEB organic is cheaper than many alternatives. Try to aim for fresher, more natural foods. More prep time, but less money.
My background is chemical engineering, and once I started to learn about plastics, I wasn't a big fan. (I won't say that I've completely phased them out, but I try to be very cautious.)
Body Products - I buy physical sunblock (which I have to order on-line). I had purchased many of my beauty products from The Body Shop because they were and continue to be pioneers in green beauty products. I used to buy from the stores, but have since become an Independent Consultant - for the discount and the income. You can read about how green they are from their corporate website.
Cleaning products - you can make many less toxic versions VERY cheaply yourself. I either do that or buy from Melaleuca.
I'd love to talk more - most of my friends are not eco-conscious, so it would be nice to share ideas with someone!
