Approximately 17 Orcas have died in Hudson's Bay over the past few years because they got stuck in the bay by the ice. The marine mammals went into the bay during the winter months when there was no ice present (during a period of warming) to stalk belugas and narwhals; however, the ice came back and the animals got stuck in the bay without food cause the animals to starve to death.
The local Orca population is estimated have around 70 individuals, which means any number of deaths could be a huge hit to the population for these long-lived whales.
Take a listen to the episode for more details on the story.

A new study was published looking at the future of global Orca populations and the results are not good. We've discussed the challenges that the Southern Resident Orca Population face with lack of Chinook Salmon and contamination problems; however, we have not yet discussed the health of other populations. The Orca study that the Guardian wrote about covers global populations.
Results of the study showed Orca populations having problems with contamination when populations were in close proximity to industrialized coastlines that dump/dumped contaminants such as PCBs. The story is not all doom and gloom.
Orca populations in more remote areas, or orcas living away from highly industrious areas such as the Arctic or Antarctic are in much better shape in the long term.
How do you think Orcas should be managed in the future? Let us know in the Facebook Group.
