Earth 2020 An Insider’s Guide to a Rapidly Changing Planet EDITED BY PHILIPPE TORTELL P HILIPPE Earth 2020 Fi� y years has passed since the fi rst Earth Day, on April 22nd, 1970. This accessible, incisive and � mely collec� on of essays brings together a diverse set of expert voices to examine how the Earth’s environment has changed over these past fi � y years, and to An Insider’s Guide to a Rapidly consider what lies in store for our planet over the coming fi � y years. T ORTELL Earth 2020: An Insider’s Guide to a Rapidly Changing Planet responds to a public Changing Planet increasingly concerned about the deteriora� on of Earth’s natural systems, off ering readers a wealth of perspec� ves on our shared ecological past, and on the future trajectory of planet Earth. ( ED Wri� en by world-leading thinkers on the front-lines of global change research and .) policy, this mul� -disciplinary collec� on maintains a dual focus: some essays inves� gate specifi c facets of the physical Earth system, while others explore the social, legal and poli� cal dimensions shaping the human environmental footprint. In doing so, the essays collec� vely highlight the urgent need for collabora� on and diverse exper� se in addressing one of the most signifi cant environmental challenges facing us today. Earth 2020 is essen� al reading for everyone seeking a deeper understanding of the E past, present and future of our planet, and the role that humanity plays within this ARTH trajectory.

Acknowledgements I am grateful, first and foremost, to all of the authors who contributed their words and insights to this volume. They worked under tight deadlines, juggling many other commitments, and were exceedingly patient with all of my many editorial suggestions. Through their eyes, I have come to a much deeper understanding of Earth’s environmental history over the past half century. I wish also to thank the group at Open Book Publishers, whose outstanding (and very rapid) work made this book a reality. Alessandra Tosi was enthusiastic about this project from the start, and marshaled the team to keep things moving forward throughout. Both Alessandra and Adèle Kreager provided excellent editorial suggestions, while Luca Baffa developed a beautiful design and layout, and Laura Rodriguez helped spread the word about this project far and wide. During the early phases of this project, Margot Young, Mark Turin and Jesse Finkelstein provided much needed advice and inspiration. Finally, I wish to thank my family for support and patience as I set aside weekends, evenings and early mornings to find time to work on this project amidst a sea of other responsibilities. I hope they agree that the result was well worth the effort. Introduction —— Philippe Tor tell n 22 April, 1970, millions of people took to the streets in cities and towns across O the United States, giving voice to an emerging consciousness of humanity’s impact on planet Earth. This first Earth Day was the brainchild of US Senator Gaylord Nelson, and was organized by a grassroots movement coordinated by Denis Hayes, a twenty-five- year-old Harvard student. The Earth Day events included demonstrations, teach-ins and community clean-ups (‘Trash Wednesday’) in over 2,000 communities across the country. Protesters shut down Fifth Avenue in New York City, while students in Boston staged a ‘die-in’ at Logan airport, lying in coffins to raise awareness about the dangers of airplane- related pollution. Demonstrators in Chicago called for an end to the internal combustion engine. The protesters were mostly white, middle-class and overwhelmingly young, but their message also reached some in the older generation. Walter Cronkite, by then widely seen as the most trusted man in America, hosted a half-hour Earth Day special on the CBS Evening News. He had become increasingly concerned about ‘the fouled skies, the filthy waters and the littered earth’, as he put it, and he concluded the news special with a call for the public to heed ‘the unanimous voice of the scientists warning that half-way measures and business as usual cannot possibly pull us back from the edge of the precipice’. Today, half a century later, Cronkite’s words are eerily familiar. Since the first Earth Day, we have, no doubt, made significant progress in addressing a range of acute environmental problems. Yet, other more pernicious threats have emerged, from climate © Philippe Tortell, CC BY 4.0 https://doi.org/10.11647/OBP.0193.01 change to global biodiversity loss; the warnings seem louder, and the edge of the precipice ever closer, as growing evidence demonstrates planetary-scale human perturbations of the Earth System. As we look back to the first Earth Day fifty years ago, understanding the environmental trajectory of planet Earth, and the societal evolution of its most dominant species — humans — provides us with important lessons from the past, and, hopefully, insights for the future. Such lessons and insights are gathered together in the present collection of essays, which mark the fiftieth anniversary of Earth Day in 2020.
