White Gold: The Diary of a Rubber Cutter in the Amazon 1896 – 1906, is a tale of humanity and the natural order working together in the midst of greed and ignorance. The crisis of the Amazon rainforest began more than a century ago when prospectors discovered the region was a rich source for rubber. This brought commercial interests into collision with the Amazon’s complex ecology—its plants, animals, and people. At the height of the rubber boom in the beginning of the 20th century, a young American, John Yungjohann, went to seek his fortune as a rubber cutter in Brazil, only to find himself struggling for survival.White Gold‘s editor, Sir Ghillean Prance, leading expert of the rainforest and former director (emeritus) of the Royal Botanical Gardens at Kew, England, has enhanced Yungjohann’s text with his own contemporary photographs and identified the fungi, plants and animals mentioned in the pages of the diary. Yungjohann’s words are especially poignant today as an onslaught of extractivist policies threaten the Amazon and rain destruction upon the region, its incomprehensible biodiversity, and the peoples to which it is home.

A defining scholarly publication on the past and current state of research with psychedelic plant substances for medicine, therapeutics, and spiritual uses.Certain plants have long been known to contain healing properties and used to treat everything from depression and addiction, to aiding in on one’s own spiritual well-being for hundreds of years. Can Western medicine find new cures for human ailments by tapping into indigenous plant wisdom? And why the particular interest in the plants with psychoactive properties? These two conference volume proceedings provide an abundance of answers.The first international gathering of researchers held on this subject was in 1967, sponsored by the National Institute of Mental Health (NIMH) and U.S. Public Health Service. It was an interdisciplinary group of specialists – from ethnobotanists to neuroscientists – gathered in one place to share their findings on a topic that was gaining widespread interest: The use of psychoactive plants in indigenous societies. The WAR ON DRUGS which intervened slowed advances in this field.Research, however, has continued, and in the fifty years since that first conference, new and significant discoveries have been made. A new generation of researchers, many inspired by the giants present at that first conference, has continued to investigate the outer limits of ethno-psychopharmacology. At the same time, there has been a sea change in public and medical perceptions of psychedelics. There is now a renaissance in research, and some of these agents are actively being investigated for their therapeutic potential. They are no longer as stigmatized as they have been in the past, although they remain controversial. There still remains much work to do in this field, and many significant discoveries remain to be made.So, in June of 2017, once again specialists from around the world in fields of ethnopharmacology, chemistry, botany, and anthropology gathered to discuss their research and findings in a setting that encouraged the free and frank exchange of information and ideas on the last 50 years of research, and assess the current and possible futures for research in ethnopsychopharmacology. The papers given at the 2017 Symposium, organized by Dr. Dennis McKenna, in a handsome two volume boxed collectors set represents perhaps the most significant body of knowledge in this interdisciplinary field available.About Dennis McKenna: He is an icon amongst psychedelic explorers, working to inspire the next generation of ethnobotanists in the search for new medicines for the benefit of humanity and the preservation of the biosphere that produces what is apparent from reading these papers – a rich pharmacopeia of medicines. Essential for academic libraries, pharmaceutical and ethnobotanical collections.

Ghillean Prance, Director of Kew Gardens, applies his knowledge as botanist and scientist and his deeply held Christian beliefs to the basic questions that surround our destruction of the earth and what we can do to change course.

Fifteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical reviews, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that no facet of evolutionary biology-classical or modern-is slighted. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061; Ghillean T.

Christianity is often accused of asserting humanity's dominion over nature - an attitude that has led to so much environmental destruction - and of viewing it as somehow 'fallen', instead of teaching that we are merely a part of creation and that 'what we do to the earth, we do to ourselves'. In fact, the Bible is teeming with information about plants and biodiversity and different animals and their behaviour, revealing that its writers, like King Solomon and the oracle Agur, had intimate everyday knowledge of the natural world around them and learned from it. Likewise, Jesus was a close observer of nature and was earthed in the here and now, as his parables show. In this book of biblical reflections botanist Ghillean Prance draws richly from his experiences exploring the Amazon and many other regions - from the White Mountains of Turkey to the Hawaiian Archipelago. It is his hope that this book will move Christians to wonder at some of the marvels of nature, and so to treat God's creation with reverence and more respect. God's Word is to be read not only in the Bible, but in God's 'big book'.
