Toxic Ingredients
The Environmental Working Group
Asbestos causes cancer and is in many of our homes and in the products we buy. Asbestos.com by The Mesothelioma Center is a for-profit site that provides many free articles and guides related to asbestos: Asbestos Products, Asbestos in Moldable Plastic Products, Asbestos in Home Goods and Toys, a Guide to Asbestos in the Home, and a Guide to Handling, Disposing and Recycling Asbestos.
Education
GreenEcoWarriors.org: Their mission is “Creating a Culture of Sustainable thinkers” through education aligned with national standards. I learned about this organization from reading Pesky Plastic: An Environmental Story by the founder and CEO of GreenEcoWarriors.
