Not Right For WatchKnowLearn
WatchKnowLearn ratings are intentionally harsher than what you might find on YouTube, for example. Most of our videos have been imported by people who want to use them with kids, not by the creators of the videos. We take a hard-nosed attitude toward quality. Four and five stars should be reserved for really excellent quality. Three stars isn't bad. Two is often watchable and shouldn't be ruled out.

  • 5 stars = Exemplary.
    Unusually helpful and well produced. Do not overuse this, please; it is not the standard rating for decent work, as it is elsewhere.
  • 4 stars = Very Good.
    Very helpful but not among the very best; adequately produced, at least.
  • 3 stars = Usable.
    Reasonably helpful, perhaps a bit amateurish in production or has some other problem; there is nothing wrong with a 3-star rating for amateur work!
  • 2 stars = Some Merit.
    Minimally helpful; not completely worthless or inappropriate; you can see how it might be useful to some people.
  • 1 star = Not Right for WatchKnowLearn.
    Not at all helpful, not educational, poorest quality, etc.; you can't see it being useful to anyone.

From snagfilms.com (Approved: Mrs Jefferies), produced by Alexandra Cousteau
 
The Expedition Blue Planet team explore the impacts of a broken river and disappearing wetlandsIn August 2010, Alexandra Cousteau’s Expedition Blue Planet crossed over the Arizona/Mexico border to follow the Colorado’s dry riverbed to its historic mouth in the Upper Gulf of California where its nutrient-rich waters no longer reach the sea.The stately Colorado, that same iconic river of history that carved out the Grand Canyon and made the deserts bloom in the American southwest, now ends in hypersaline mudflat rather than a punctuation mark of aquatic biodiversity. Our unsustainable demands and shortsighted management of the Colorado River literally exhaust its supply; its 1,450-mile long path now ends in the dust and shimmering heat of the Mexican desert.In Death of a River, Alexandra and her team join Ornithologist Dr. Osvel Hinojosa-Huerta and agriculture and water expert Dr. Yamillet Carrillo-Guerrero to explore the impacts of a broken river and disappearing wetlands. Our loss is not only calculated in the collapse of more than 2 million acres of wetland - a fertile delta the size of Rhode Island - but also the impoverishment of critical estuaries where the river once met the sea.
