The Emerald Planet: How Plants Changed Earth's History by
David Beerling
My rating:
3 of 5 stars
This is something in between a history of plants on Earth, and a set of essays on that theme. It does start with the development of leaves, and then moves on to the plants' creation of massively high oxygen levels in the Carboniferous (the era of dragonflies with 5' wings) so the first two chapters felt like it would be a tour of plant evolution.
This is probably far too broad a topic, and in any event is not what we get. Nothing about the evolution of flowers or the period worldwide redwood forests, for example. Instead the themes are not merely what was important to plants, but when plants were important to the climate, or even our understanding, through fossils, of the climate. This is a fascinating picture of a dynamic planet, constantly changing in response to a dance between geological processes and plants, which respond and then change the atmosphere and soil in turn.
The chapters cover the science with some technical detail, but also the history of the science, and in some cases the quirks of the scientists. The implications of these sorts of changes to modern day climate change is mentioned more than once, but happily the science is treated as interesting on its own terms, rather than a tool for the present. Some of the research referenced seems cutting edge, which is actually both a complement and a concern--I'd expect at least one or two of the stories to change as we learn more about the distant past. (Not a knock on Beerling, who is quite up front about uncertainties.) My only other nitpick is my ebook was missing the full color plates.
For my own reference the chapters are below--spoilerized, although the stories are tens of millions of years old, it's probably better to just read the book.
