The first line of the article.
Most people use the term "roll back" to refer to a reversal of something that was actually put into effect.

Would you like more?
edit: No? One example was enough? But I had so much more. :(
The example you reference is modifying rules put in place just a few years ago, so at best it's an obviously mediocre example.
Why would I alter my comment to be in tune with what you want when I was responding to this:
>Exactly what environmental protection is Trump rolling back?
I asked for a concise description, I didn't ask you to modify your comment. Surely the environmental protection roll-backs will cause pollution problems (even if it's not of the scale that existed 30+ years ago). If it's too much to ask that you explain how your examples will cause meaningful environmental damage, and you don't want to provide such an elaboration, I understand.
Who was I commenting to? You or the user whose post my comment showed up under?
> So let's have all those examples
But that is not what you asked for. Try again, smarter not harder.
