I have been a supporter of the Environmental Working Group for many years. They provide important information about environmental toxins that contribute to disease, such as which fruits and vegetables contain the most pesticides and should be bought organic, and which sunscreens and personal care products are safe for children and adults. I rely on them heavily and tell people about them all the time.
The EWG is one of the most effective environmental justice and public health organizations in the world. They have some of the most compelling research available free to the public. I use EWG's research to compare radiation levels of cell phones. I also use EWG.org to find out what chemicals are in my cities drinking water as well as finding the safest sunscreens and other cosmetics. The Environmental Working Group or EWG perform lab test, compile data, take surveys, engage the public, work with local and federal government to ban toxic chemicals from products, and also they educate families on healthy living. The provide a highly advanced and super informative website. EWG'S Ken Cook is really an incredible public health expert if I have ever seen one.
This organization seems to be raising public awareness and getting legislation passed to protect consumer and children's health. I use their safe cosmetics database all the time to look for shampoos, baby lotions, sunscreen, lipstick that are less toxic. I read about their research - such as the latest report on rocket fuel chemicals found in baby formulas - frequently in NYT and other major media. I am impressed by the depth and breadth of their work.
