Richard Powers’s prize-winning Overstory was an impassioned evocation of the natural world and a call to arms to save it. In his latest novel, Bewilderment, a father and son navigate a world seemingly bent on destruction. Powers tells Andrew Marr how the father, an astrobiologist, models planets in far away galaxies searching for life, while his nature-loving 9 year old struggles to understand why earth’s life forms are so thoughtlessly destroyed.

Mya-Rose Craig, aka ‘birdgirl’, is a young British-Bangladeshi ornithologist and activist. From a deep love of bird watching she has gone on to become a prominent environmentalist. In ‘We Have A Dream’ she speaks to 30 young indigenous people of colour to find out how their environments have been affected by climate change, and why young people are so involved in protecting the natural world.

The journalist Simon Mundy argues that climate change is affecting more than just the environment: everything from energy, farming, technology and business, as well as migration. In Race for Tomorrow, Mundy has travelled the world talking to the people at the front line of this transformation, from those battling to survive the worst impacts, to those eager to reap the financial rewards.
