NOAH'S CHILDREN tells the story of an individual who awakens to the many environmental crises threatening our ways of life. While global warming, visible and documented in countless cases, is the one great challenge to human existence as we have known it, a number of other developments also threaten us, including extinctions, habitat loss, poisonings, over-fishing, environmental degradation, loss of bio-diversity, consumption habits, and population growth. So what can an individual do? This story, of a journalist/biologist and father, offers some ideas. But ideas must include strategies for implementation, which require cooperation among many -- a requirement susceptible to the imperfections of the species.
