Le pitch de ce reportage est très certainement ironique, il serait surprenant que la journaliste ne l’ait pas fait exprès, mais il me semble que les entretiens sont sérieux, et que même les commentaires soient assez neutres, ou en tout cas je ne suis pas assez bon en anglais pour y avoir perçu de l’ironie :

Grizzly bears go vegetarian due to climate change, choosing berries over salmon

The study found that during the unusually warm summer of 2014, the bears, which would traditionally kill up to 75 percent of the salmon, were nowhere to be seen near the streams.

Instead, they were in the hills busy munching on berries, which contain less protein and therefore take less energy to break down, causing them to gain weight more quickly.

Biologists warned that changes caused by a warming planet were behind the bears’ unusual behavior and could affect the entire ecosystem.

The researchers found that the forests around the streams suffered because the bears’ fish carcasses were no longer there to enrich the soil.

“Bears switched from eating salmon to elderberries, disrupting an ecological link that typically fertilizes terrestrial ecosystems and generates high mortality rates for salmon,” the study said.

On average, red elderberries are said to be ripening two and a half days earlier every decade.

If the pattern continues, they will regularly overlap with the salmon by 2070.

The study was published in the Proceedings of the National Academy of Sciences.
