I was watching a show about a veternarian in Alaska/Yukon-can’t recall. She had to go check on an Elk herd (I think) because the males were not breeding with the ladies and should have been in rut.
While checking out the boyz junk, she measured their “scrotums” and discovered that they were really small for their age.
And one reason the narrator gave us for the small sizes of their business end, besides diet and bugs, was- you guessed it- “climate change”.
I would think that being locked up may have had something to do with it, but it is amazing how they always manage to weave it into everything....the reason du jour....
I used to watch a lot of animal documentaries with my children when they were younger. It seemed the last five minutes always had the obligatory "humans are bad" segment. And that was before the climate change mantra became the rage.
