Sudden interest in change management

Are people more concerned about environment or change?

In the past 7 days my lens on Our Iceberg Is Melting, which is a book on Change Management - despite the green title, has received 42 hits.

Ok! It is not as if this lens is getting some hundreds of thousands of hits per day; but considering the fact that it used to get some 6-7 hits per week this is a 6-fold jump.

I wonder if this sudden interest in change management is triggered by environment or economy.
