What does ー mean in this context?


(I'm sorry if it is a duplicate, I tried to search unsuccessfully)

After 変わりつつある:

> 農業の現場で起きている担い手不足によって、日本人の食卓の景色も変わりつつある **ー** 。
> 取材を通してそうした実感を抱きました。([source](https://www3.nhk.or.jp/news/html/20180424/k10011415381000.html))

I don't have the impression it generally appears in NHK news article...?




It's a ダッシュ. It also works [like an English em-
dash](https://japanese.stackexchange.com/q/12761/5010), but here it's adding
an "emotion" to the sentence. It makes the sentence look somewhat like a
monologue. Its purpose here is the same as Japanese 三点リーダー (`…`) or English
ellipses.
