PBS is giving audiences another reason to stay indoors and stay warm next month with the release of another episode of its hit wildlife series Nature on DVD.
PBS will release Nature: Invasion of the Killer Whales on Tuesday, January 20th. Nature: Invasion of the Killer Whales focuses on a major change in the ecosystem of the Arctic. It is a change that has resulted from global warming and the gradual disappearance of Arctic ice. As the once massive amounts of ice that one populated the Arctic disappear, so does the number of killer whales inordinately increase. The number of killer whales increases because they are being provided with more territory in which to hunt. By contrast, it also means that there is less territory in which polar bears—the once kings of the arctic—have to hunt.
Audiences are presented interviews with native Inuit who discuss the increasing number of killer whales in the Arctic and how it has actually helped them. At the same time, the other side of the proverbial coin is presented as scientists discuss how both humans and killer whales hunting the narwhal is not necessarily a good thing as it increases competition for resources. They go on to argue that this could greatly and negatively affect the lifestyle of the Inuit people. They go on to argue how the decrease in Arctic ice could lead to drastically negative effects on the polar bear population, too.
Nature: Invasion of the Killer Whales will retail for $19.99. It can be ordered online direct from PBS’ online store at http://www.shoppbs.org/product/index.jsp?productId=51197006&cp=1378003.2831221&sr=1&origkw=nature&parentPage=family.
