Screening of "Toxic Baby" - a cinematic documentary by Penelope Jagessar Chaffer

Banquet/Gala - Renaissance Pere Marquette Hotel Ballroom

Toxic Baby, the movie"The TOXIC BABY project is the feature length documentary, authored by filmmaker and mother of one Penelope Jagessar Chaffer, website and supporting new media that explores the role that chemicals may be playing in the lives and health of our children. A dramatic rise in chronic childhood diseases has been seen across the western world with skyrocketing rates of asthma, developmental disabilities like autism and certain juvenile cancers to name a few, as well as a rise in certain adult onset diseases like testicular cancer which are all being linked to the increasing chemical exposure that we and our babies face. “Internal Environmentalism”, the phrase coined by the production to help explain the issue, is shaping up to be one of the most challenging debates we face as a society and in the years spent researching and making this film, the production has had unprecedented access to a wealth of information regarding this topic. The aim of the film and this site is to share that information and to provide the most up to date thinking on the issue, providing a host of downloads and links for a more informed experience of the issue of toxicity and its role in the lives of children in the twenty first century."

by Artist Dawn DeDeaux, with Tulane / Xavier Bioenvironmental Research Center. The Tulane / Xavier Center for Bioenvironmental Research, led by Deputy Director Doug Meffert, D. Eng., is working on a project developed by Public Artist Dawn DeDeaux titled PROJECT MUTANTS  - a multi-phased program offering water-sensoring, illuminated floating sculptures for launch in international waterways, starting with the Mississippi River and the coastal wetlands of the Gulf of Mexico.  The light-responsive sculptures will detect chemicals and hormones in lakes, rivers and estuaries;  providing a "face" to an invisible environmental threat and a focal point for coordinated public education campaigns.  e.hormone conference participants are encouraged to join this highly collaborative effort that merges art, science, education and civic engagement to raise public awareness and collect scientific data.
