Development along the rivers directly related to reduced ice formation in the Arctic was listed as potential threat to the belugas of Manitoba. The difference between these river sanctuaries and the St. Lawrence where massive development has caused negative effects and subsequent “threatened” classification of that beluga whale population is vast. However a future change in commerce due to global warming could change things for Hudson Bay belugas in a hurry.A direct consequence of arctic ice melt would be increased shipping leading to extensive noise pollution that would harm the belugas ability to echo-locate and communicate with one another. Warming trends also have implications on the beluga’s winter feeding grounds in the Hudson Strait in the northeast. The ice harbors algae that sustain fish that belugas prey upon as well serving as a safe haven for the belugas hiding from killer whales. These predators are quite common in the bay in recent years due to more access from longer ice free periods.A key consideration in Churchill, and more specifically the Churchill River, is the long term strategy of the Port of Churchill, currently in the process of changing ownership. The relationship and interactions between the port and the belugas to date have been very good. With new owners and possible new directions in shipping from the facility it is important to cover all the angles with regards to water contamination and shipping routes and frequency.
With belugas coming to Churchill each summer there has been an increase in tourism as a result. The economic benefits from this would be adversely affected if protection was not placed on the estuary.

Because of these current and impending threats, advocates and researchers are intent on protecting the clean estuaries now before the need becomes dire. Once development ensues to a higher degree as a result of environmental change it could be too late Thinking ahead and protecting these areas now is crucial!
