    Their conclusion stems from Svensmark's research which has shown the previously unsuspected role that cosmic rays play in creating clouds. During the last 100 years cosmic rays became scarcer because unusually vigorous action by the Sun batted away many of them. Fewer cosmic rays meant fewer clouds--and a warmer world. The theory, simply put here but explained in fascinating detail, emerges at a time of intense public and political concern about climate change. Motivated only by their concern that science must be trustworthy, Svensmark and Calder invite their readers to put aside their preconceptions about manmade global warming and look afresh at the role of Nature in this hottest of world issues.

    Now 'the greatest living advocate of the global ecosystem' this is the story of the voyages that started it all. Staying with local tribes while trekking in search of giant anteaters in Guyana, Komodo dragons in Indonesia and armadillos in Paraguay, he and the rest of the team battled with cannibal fish, aggressive tree porcupines and escape-artist wild pigs, as well as treacherous terrain and unpredictable weather, to record the incredible beauty and biodiversity of these regions.

    MacKinnon realized the grassland he grew up on was not the pristine wilderness he had always believed it to be. Instead, his home prairie was the outcome of a long history of transformation, from the disappearance of the grizzly bear to the introduction of cattle. What remains today is an illusion of the wild--an illusion that has in many ways created our world. In 3 beautifully drawn parts, MacKinnon revisits a globe exuberant with life, where lions roam North America and 20 times more whales swim in the sea. He traces how humans destroyed that reality, out of rapaciousness, yes, but also through a great forgetting. Finally, he calls for an "age of restoration," not only to revisit that richer and more awe-filled world, but to reconnect with our truest human nature. MacKinnon never fails to remind us that nature is a menagerie of marvels. Here are fish that pass down the wisdom of elders, landscapes still shaped by "ecological ghosts," a tortoise that is slowly remaking prehistory. "It remains a beautiful world," MacKinnon writes, "and it is its beauty, not its emptiness, that should inspire us to seek more nature in our lives."
