Those of us who do want to lower their own impact, should first of all acquire a carbon instinct, a good grasp of the kinds of numbers we're talking about when we want to say something like "Eating meat causes 'lots of' greenhouse gas emissions." This book is intended to help us build such an instinct: it's filled with information about the greenhouse gas emissions associated with all kinds of things, from foodstuffs to books, emails, modes of transport, and more.
