Changes

Bill Butterworth thinks recycling of waste to land is the answer. Most people know that farmers traditionally used manure from livestock to fertilise their land. Few people know that traditionally they also took local waste for composting and after time, used that too as fertiliser. Post-climate change, Butterworth's suggestion is that proximity recycling of waste can be used by farms to produce biofuel for local use and food for wider use, creating a kind of closed loop system in which food and fuel is grown from composts made from wastes, pumping oxygen back into the sytem. The key to this idea is that the closed loop does not rely on matter exchange with any part outside of the system.

Butterworth has an informal style and is mostly very easy to read. However, the book - necessarily - does go into quite a bit of detail, and sometimes the narrative flow suffers for it. I don't think it's anything that could have been easily avoided though. Proofreading falls down a little and some tougher editing might have tightened it up a little. Overall, the book reads like a presentation or long talk, and is absolutely appropriate to the practical approach to the topic.
