NOVA: "MAKING NORTH AMERICA"
PBS, 9:00 p.m. ET
Part 3 of 3. This three-part series, explaining the development of our continent and the plant and animal life that populated it, concludes tonight. If there’s ever a sequel, it probably will measure the effects of global warming and climate change – but I digress. Which, in this case, might be considered a case of continental drift.
