ELI5: How come nobody talks about the dangers of acid rain anymore?

When I was a kid in the 1990s, school taught us all about this environmental scourge. (I remember thinking literal acid was going to fall on me). Now, it's not. What's happened to eradicate the problem?

Countries around the world, especially industrialized countries started to set limitations for sulfur emissions from combustion engines and power plants. It is still an issue, but not a huge one. But for example currently there are efforts to limit sulfur emissions from marine traffic for the same reasons.

On a related note we don't talk about the ozone layer that much either, because governments started limiting the use of ozone depleting substances, allowing the ozone layer to start recovering.

Now, let's hope governments would agree limiting greenhouse gases.
