What smells are disappearing?

I just read this interesting Article about certain smells that are disappearing for a variety of reasons, such as certain chemicals now being obsolete, or new technologies replacing older technologies that used items with certain scents, or laws that prohibit certain activities that were associated with distinctive aromas.

Can you think of any other smells that are rapidly disappearing or already gone from our modern life, or will possibly be gone in the future?

It’s interesting to think that some smells that were common during our childhoods are no longer around, or will not be around when our grandchildren are adults.

Are there some scents that you already miss? Are there some smells that you are glad that they have vanished?
