We always hear the same old green advice ... fly less, turn the thermostat down, drive a hybrid car. But what about all the other things we buy and do? Part green-lifestyle guide, part popular science book, How Bad Are Bananas? is the first book to provide the facts we need to make carbon-savvy purchases and lifestyle decisions. It also helps put things into perspective with entries for the big things (bushfires, volcanic eruptions and the Iraq war) as well as the little things (newspapers, sending a letter, a pint of beer). This book is packed full of surprises - a plastic bag has the smallest footprint of any item listed, while a block of cheese is fairly bad news for the climate - and continuously informs, delights and engages the reader.
