There are lots of possibilities. Habitat destruction, a new invasive predator, *colder* than usual temperatures, cyclical disease in the populations. “Scientists” can be really dumb sometimes.
Exactly.
Colder for sure, I live in the North East, and I can testify to that.
And when they mention habitat destruction, how much of this is caused by invasive species these same wing-nuts have brought here?
Or too many deer that can’t be shot except when and where our “officials” say we can?
