Book excerpt: Welcome home. A place 200 million years in the making. Long ago, our planet had only one gigantic land mass. Then something monumental happened. That supercontinent ruptured and seven different worlds were born. Each of those worlds - or continents - evolved, and continues to evolve, its own way of life. From the jungle of the Congo or the majestic Himalayas to the densely populated wilds of Europe or the comparatively isolated Australasia, Seven Worlds, One Planet explores the natural wonders that give each of our continents its distinct character. Following the animals that have made these iconic environments their home, it discovers spectacular wildlife stories that reveal what makes each of these seven worlds unique. With a foreword by Sir David Attenborough and over 250 breathtaking images, including stills from the BBC Natural History Unit’s spectacular footage, Seven Worlds, One Planet is a stunning exploration of the planet, and the worlds within it, that we call home.
