Kolbert's "Sixth Extinction"

I was surprised by how readable Kolbert's book was for me. Usually, I tend to levitate towards novels and fictional stories, such as Orzeki's "All Over Creation." I did not have high hopes while starting Kolbert's "Sixth Extinction," but it was actually written in clear language and framed by an interesting lens. There were clear cause-and-effect chain of events, and I found myself eager to follow the direction Kolbert was taking me. I was incredibly surprised that the culprit behind the dying frogs was not directly humans -- rather it was indirectly humans by way of a mysterious bacteria that humans had spread through migration and globalization.
