The study of how substances alter gene expression is part of the field of epigenetics. Some chemical exposures appear to turn on and turn off genes in ways that disregulate cell growth and predispose for cancer. From this perspective, our genes are less the command-and-control masters of our cells and more like the keys of piano, with the environment as the hands of the pianist.

Here in the United States, a study of nearly 700 women in California showed an increased risk of fetal death among babies whose mothers lived near crops when certain pesticides were sprayed. The largest risks were found among pregnant women exposed during the critical first trimester and among those who lived in the same square mile where pesticides were used.

The scientific analysis that is supposed to provide our Governor the facts and information he needs to make a crucial decision was crafted with the guidance of the gas industry, not of the state's scientists.

As currently written, the laws require certain manufacturers and users of such chemicals to report any and all environmental releases-either accidental or routine-to air, water, or soil. The Toxics Release Inventory is the main registry of such events, and it is available to the public through the Environmental Protection Agency. It is hardly comprehensive. Toxic emissions reported to the federal government are thought to account for only 5 percent of all chemical releases.

Drink a bottle of French water and then step into the shower for ten minutes and you've just received the exposure equivalent of drinking a half gallon of tap water. We enjoy the most intimate of relationships with our public drinking water, whether we want to or not.

In the world outside this glass room, songbirds are feeding and resting in the trees. Some will take off tonight and not land until they reach Venezuela. Sandpipers, plovers, and broad-winged hawks have already left for Patagonia and Panama. Bats are headed for caves in Kentucky and Tennessee. Out in the Atlantic, humpback whales pass by on their way to the Caribbean. Even now, Canada geese are honking toward us from Quebec. It is a good day for the beginnings of journeys.Every time I look at you, I think, Now I cannot die.

From the right to know and the duty to inquire flows the obligation to act.
