Green Group discussion

I'll run a quarterly Challenge. We're now in Spring, or Autumn in the Southern Hemisphere, so you have three months to participate and hit your personal targets.

The new Challenge is to read a book this quarter, or more than one, which is non-fiction, and about the natural environment.

Sign up to the challenge on top of the Home Page.
You can say how many books you aim to read - one, five, ten.
You will be asked which shelf the books are on - if you choose challenge, or environment, and you do not have a shelf of that name, Goodreads will put one into your personal bookshelf.

Then come here to tell us your titles!
Authors may read their own books for the Challenge, so it's okay to mention them in this thread.

Shelve the book before or during the read, and when you mark it as read, Goodreads will see that and update your challenge score.

I am currently reading Regenesis: Feeding the World Without Devouring the Planet by George Monbiot.
