This is something I've been watching and thinking about for many years as tangential to a primary interest. It's not all bad as there have been many benefits to these changes too.

There are the usual culprits that people talk about and others which people don't seem to think about much. Looking forward to reading the book mentioned in the article to see someone else's in depth thoughts.
