Whether you are new to ecology, a student of the subject, or simply concerned about what is happening to our planet, this is an essential introduction to the environment and climate change. Fully revised and updated with eight brand-new pages of content, The Ecology Book is a truly accessible and comprehensive guide to what is arguably the most important subject of our time.
