PLANET EARTH: BLUE PLANET II
BBC America, 9:00 p.m. ET
SERIES FINALE: There’s actually a Making of the Blue Planet II special still to come, but tonight’s episode is the final, stunning installment of the Blue Planet II series proper. In it, we see Sir David Attenborough, on camera as well as narrating, explaining why our planet’s ecosystem has arrived at a precarious point. But it also shows examples of reversing the tide, so to speak, with tales of dedicated scientists and environmentally concerned lawmakers working around the globe to change, effectively, the threatened populations of leatherback turtles, sperm whales and other literally irreplaceable species and environments.
