This topic could go in the health or the Knowledge Sub Forums but the work was done by scientists so I put it here.

Beluga whales are cultural social charismatic mammals who rely on sound to communicate.

In January 2016 David Suzuki made a TV program about a beached baby Beluga that was rescued and taken back to the whale habitat. They don’t know how the story ends, but a female with her own calf seemed to adopt the baby. The females will babysit and even nurse strange babies, so they are hoping that their idea worked and it seems that is what happened.

This link is about a similar more recent story in June of this year.

A good lesson for humans - When chemical contaminants in the St. Lawrence River were reduced, the cancer rates in the Belugas dropped to almost non existent. And we wonder why there is so much cancer in humans these days?


Belugas need ice which is decreasing. Scientists studied the effects of noise on Belugas and with facts to back them up, a pipeline terminal was not built, quieter ferries were designed, and shipping companies changed routes to miss Beluga birthing zones. Protection of critical habitat was focused on at the marine park. They are doing what they can to help the Belugas, even if they can’t stop global warming and give them back their ice.

“In the 1970s, scientists revealed serious problems related to chemical contaminants such as PAHs and PCBs, which led to regulatory changes. We’re beginning to see the benefits of these measures: some of these contaminants, which were present in record concentrations in belugas in the 1980s, have since declined. Cancers, which were the main cause of mortality in adults in the 1980s and 90s, have also become less frequent. No beluga born after 1971 has died from cancer. But at the same time, the population is suffering from other problems, most likely related to climate change. It’s very worrisome.”
 
...Researchers point out that the beginning of the decline coincides with a combination of significant changes in the St. Lawrence ecosystem. Rising water temperatures, reduced ice cover in the winter and changes in the abundance and distribution of prey all represent unfavourable conditions for this already fragile population. The rapid rise of a new class of contaminants through the early 2000s and the increase in maritime traffic and disturbance in the Upper Estuary further contribute to the degradation of beluga habitat.”




It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.

.....allows contamination ?

I am a layman.
