And I think it reasonable to ask—nearly a half century after Silent Spring alerted us to a possible problem—why so much silence still surrounds questions about cancer’s connection to the environment and why so much scientific inquiry into this issue is still considered “preliminary.”

From dry-cleaning fluids to pesticides, harmful substances have trespassed into the landscape and have also woven themselves, in trace amounts, into the fibers of our bodies. This much we know with certainty. It is not only reasonable but essential that we should understand the lifetime effects of these incremental accumulations.
