Meet geology student Alexandrea Bowman in this video profile from NOVA scienceNOW: The Secret Life of Scientists & Engineers. Bowman explains that Native American belief, which teaches we must conserve and preserve the land for the next seven generations, has influenced her decision to study geology. She describes her research on contaminants present in Long Island Sound—specifically, mercury. Contaminants flow down rivers before settling out in the Sound. Toxic contaminants, including mercury, may end up absorbed in the fat of fish, posing a serious health risk to humans who eat the fish. This resource is part of the NOVA: Secret Life of Scientists & Engineers Collection.
