Given Half a Chance is both a snapshot of our world and a call to arms, setting out the most pressing environmental challenges that we face while making a passionate case for why we need to meet them.

From fields of solar panels in Nevada to the flourishing agricultural landscapes of Ethiopia; from the traditional water harvesters of northern Rajasthan to Britain’s inspiring waste campaigners; from the savannas of Northern Kenya teeming with elephants to the clear skies above Scandinavian cities, amazing things are happening right now across the world. People are acting with hope and courage, against all the odds, to make things better.

The challenge before us is to go to scale and to replicate these successful approaches elsewhere, fast: this book draws on firsthand experience and interviews with many of the world’s leading experts to show how.
