Planet Earth’s many landforms can be breathtaking to behold. Plate tectonics has given us a basic framework to explain their formation, but there is far more to this story than that. I recently mentioned wanting to learn more about geology, having shunned the subject in favour of biology at university. So, fascinated by photos of folded rocks that look like so many layered cakes that had an accident in a bakery, and freshly armed with some basic knowledge of geology after my recent review of Essentials of Geology, Haakon Fossen’s Structural Geology seemed like a good starting point to deepen my knowledge further.
This book is an example of what happens when you go down rabbit holes. I have been reading several books on the subject of palaeontology and geology lately, and I know that the face of the earth has shifted over the hundreds of millions of years of deep history covered in these books. But where were all the continents at different times? Many will have seen the iconic maps of the supercontinent Pangaea. But I want to know more. What happened in between? And before? As Nield tells in Supercontinent: 10 Billion Years in the Life of Our Planet, Pangaea was only one of several such supercontinents in Earth’s history. But I want to know more still. Where exactly were the continents located? And how did they move? Several accessible books have provided snapshots of iconic moments, such as the formation of the Himalayas (Mike Searle’s Colliding Continents: A Geological Exploration of the Himalaya, Karakoram, & Tibet) or the disappearance of the Tethys ocean (Dorrik Stow’s Vanished Ocean: How Tethys Reshaped the World). But I want to know more! This technical reference work contains lots of fantastic palaeogeographical maps that answered all my questions.
Most people would agree that it is important to conserve wildlife and the environment it lives in. But can you clearly articulate why? Defending Biodiversity brings together an ecologist and two philosophers to critically examine the arguments environmentalists often put forward in favour of biodiversity conservation. Because, as they point out, a lot of these arguments are not very strong, and sometimes conflict with each other, or with other parts of what environmentalists wish to achieve. Now, before you get all worked up, all three authors strongly believe that biodiversity ought to be conserved, and this book is not an attack on environmentalists or biodiversity conservation. They are careful to avoid being unnecessarily controversial with this book. Rather, they want to help environmentalists improve and strengthen their arguments and to become more persuasive in debates.
It has become cliché to say that we know more about the surface of Mars than we do about the depths of our oceans, inaccessible as they are to us landlubbers. Nevertheless, technological advances have allowed us to discover more and more about the denizens of the deep. Anyone who has watched Blue Planet II or similar recent documentaries can testify to the bizarre and wonderful life forms that can be found there.
After recently reading Doudna & Sternberg’s book A Crack in Creation, this book was the next one I wanted to read to learn more about CRISPR-Cas9, the new technique to edit genetic material that has been taking the world by storm. As it turns out, it was the right order to read the books in. If you have not heard of CRISPR before, I recommend you have a look at my review of Doudna’s book first.
