Tim Flannery is one of the world's great thinkers, environmental scientists and writers. Sir David Attenborough once described him as being 'in the league of the all-time great explorers like Dr David Livingstone.'

This definitive collection of his work brings together thirty years of essays, speeches and occasional writing on palaeontology, mammology, environmental science and history, including the science of climate change and the challenges and opportunities we face in addressing this issue, so critical for all of us.
