Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.
Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

He became obsessed with fish during his early childhood and carried this passion with him throughout his career. Mike Bruton was born in the town where the first living coelacanth was discovered and studied at Rhodes University in South Africa at the same time as the great ichthyologist, Professor JLB Smith, who described ‘old fourlegs’. He subsequently became Director of the Ichthyology Institute established in Smith’s name and pioneered searches for the coelacanth off the coast of southern Africa and in the Western Indian Ocean using the German research submersible, ‘Jago’. Together with colleagues from South Africa, the USA, Canada and Germany he made many new discoveries on the biology of this extraordinary fish and campaigned internationally for its conservation.
Mike’s research on the freshwater fish of Africa and the Middle East lead to entanglements with crocodiles, hippopotami, giant snakes and military operations but also allowed him to contribute to international efforts to conserve wetlands and endangered species. He also made major contributions to our understanding of the ways in which fish are adapted to their watery environments and how they made that epic evolutionary transition from water onto land.
Whether or not you are a fisherman, aquarist or sushi eater, you will be fascinated by these astonishing tales of a man who almost became a fish!
Almost Human is the personal story of a charismatic and visionary palaeontologist, a rich and readable narrative about science, exploration, and what it means to be human.
In 2013, Wits University reasearch professor Lee Berger caught wind of a cache of bones in a hard-to-reach underground cave near Johannesburg. He put out a call around the world for collaborators – men and women small and adventurous enough to be able to squeeze through 8-inch tunnels to reach a sunless cave 40 feet underground. With this team of ‘underground astronauts’, Berger made the discovery of a lifetime: hundreds of prehistoric bones, including entire skeletons of at least 15 individuals, all perhaps two million years old. Their features combined those of known pre-hominids with those more human than anything ever before seen in prehistoric remains. Berger's team had discovered an all new species: Homo naledi.
The cave proved to be the richest pre-hominid site ever discovered, full of implications that challenge how we define ourselves as human. Did these ancestors of ours bury their dead? If so, they must have had an awareness of death, a level of self-knowledge: the very characteristic we used to define ourselves as human. Did an equally advanced species inhabit Earth with us, or before us?
Addressing these questions, Berger counters the arguments of those colleagues who have questioned his controversial interpretations and astounding finds.
To understand modern principles of sustainable management and the conservation of wildlife species requires intimate knowledge about demography, animal behavior, and ecosystem dynamics. With emphasis on practical application and quantitative skill development, this book weaves together these disparate elements in a singlecoherent textbook for senior undergraduate and graduate students. It reviews analytical techniques, explaining the mathematical and statistical principles behind them, and shows how these can be used to formulaterealistic objectives within an ecological framework.

'Plastic waste is one of the greatest environmental challenges facing the world' Theresa May 'We have a responsibility, every one of us' David Attenborough ........................................................................................ Plastic pollution is the environmental scourge of our age. And it is everywhere. Up to 12.7 million tonnes of it enter the ocean every year. That's almost a rubbish truck every minute. Hundreds of thousands of animals die every year because of it and there could be more plastic in the fish in the ocean by 2050. So what can we do? Will McCallum has been leading Greenpeace's campaign against plastic and now he shares all that he has learned to help you make a difference. And it all starts with 5 steps: 1) Go on a plastic-free shopping spree 2) Go on a plastic-free purge 3) Do some plastic-free preaching. 4) Make some plastic-free plans. 5) Start your own plastic-free campaign. This expert and accessible guide covers all ground, from the easy wins such as using a keep cup for your morning coffee, to the lesser-known hacks like using a wash bag in your washing machine to catch harmful plastic microfibres. But it will also help you be part of something bigger, explaining how to lobby successfully for impactful legislation, and how to pressure big corporations to make changes on a global scale. This is a call to arms - to join forces across the world and to end our dependence on plastic. Plastic is not going away without a fight. We need a movement made up of billions of individual acts, bringing people together from all backgrounds and all cultures, the ripples of which will be felt from the smallest village to the tallest skyscrapers.

The Last Rhinos - Lawrence Anthony
Heredity is redefined in this sweeping, resonating overview of a force that shaped human society—a force set to shape our future even more radically.
Award-winning, celebrated New York Times columnist and science writer Carl Zimmer presents a profoundly original perspective on what we pass along from generation to generation. Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities...
But, Zimmer writes, “Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are—our appearance, our height, our penchants—in inconceivably subtle ways.” Heredity isn’t just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors—using a word that once referred to kingdoms and estates—but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer’s lucid exposition and storytelling, this resounding tour de force delivers it.
Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world’s best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.
`Brilliant' Guardian `Fascinating and often delightful' The Times SHORTLISTED FOR THE 2017 ROYAL SOCIETY SCIENCE BOOK PRIZE What if intelligent life on Earth evolved not once, but twice? The octopus is the closest we will come to meeting an intelligent alien. What can we learn from the encounter? In Other Minds, Peter Godfrey-Smith, a distinguished philosopher of science and a skilled scuba diver, tells a bold new story of how nature became aware of itself - a story that largely occurs in the ocean, where animals first appeared. Tracking the mind's fitful development from unruly clumps of seaborne cells to the first evolved nervous systems in ancient relatives of jellyfish, he explores the incredible evolutionary journey of the cephalopods, which began as inconspicuous molluscs who would later abandon their shells to rise above the ocean floor, searching for prey and acquiring the greater intelligence needed to do so - a journey completely independent from the route that mammals and birds would later take. But what kind of intelligence do cephalopods possess? How did the octopus, a solitary creature with little social life, become so smart? What is it like to have eight tentacles that are so packed with neurons that they virtually `think for themselves'? By tracing the question of inner life back to its roots and comparing human beings with our most remarkable animal relatives, Godfrey-Smith casts crucial new light on the octopus mind - and on our own.

Enter a hidden world of snail killers, silly names and crazy sex in The Secret Life of Flies. Entomolologist Erica McAlister dispels many common misconceptions and reveals how truly amazing, exotic and important these creatures really are. From hungry herbivores and precocious pollinators to robberflies, danceflies and the much maligned mosquito, McAlister describes the different types of fly, their unique and often unusual characteristics, and the unpredictable nature of their daily life. She travels from the drawers of wonder at the Natural History Museum, to piles of poo in Ethiopia, via underground caves, smelly latrines and the English country garden. She discovers flies without wings, rotating genitalia and the terrible hairy fly, while pausing along the way to consider today's key issues of conservation, taxonomy, forensic entomology and climate change. Combining her deep knowledge and love of flies with a wonderful knack for storytelling, Erica McAlister allows us to peer - amazed and captivated - into the secret life of flies.
Could psychedelic drugs change our worldview? One of America's most admired writers takes us on a mind-altering journey to the frontiers of human consciousness When LSD was first discovered in the 1940s, it seemed to researchers, scientists and doctors as if the world might be on the cusp of psychological revolution. It promised to shed light on the deep mysteries of consciousness, as well as offer relief to addicts and the mentally ill. But in the 1960s, with the vicious backlash against the counter-culture, all further research was banned. In recent years, however, work has quietly begun again on the amazing potential of LSD, psilocybin and DMT. Could these drugs in fact improve the lives of many people? Diving deep into this extraordinary world and putting himself forwardas a guinea-pig, Michael Pollan has written a remarkable history of psychedelics and a compelling portrait of the new generation of scientists fascinatedby the implications of these drugs. How to Change Your Mind is a report from what could very well be the future of human consciousness. 'His approach is steeped in honesty and self-awareness. His cause is just, his thinking is clear, and his writing is compelling' - Washington Post 'An easy-going humane generosity ... mischievous self-regard ... as if Henry David Thoreau had had an encounter with Woody Allen and never been quite the same since' - Simon Schama

Native to the Kalahari Desert, Hoodia gordonii is a succulent plant known by generations of indigenous San peoples to have a variety of uses: to reduce hunger, increase energy, and ease breastfeeding. In the global North, it is known as a natural appetite suppressant, a former star of the booming diet industry. In Reinventing Hoodia, Laura Foster explores how the plant was reinvented through patent ownership, pharmaceutical research, the self-determination efforts of indigenous San peoples, contractual benefit sharing, commercial development as an herbal supplement, and bioprospecting legislation. Using a feminist decolonial technoscience approach, Foster argues that although patent law is inherently racialized, gendered, and Western, it offered opportunities for indigenous San peoples, South African scientists, and Hoodia growers to make claims for belonging within the shifting politics of South Africa. This radical interdisciplinary and intersectional account of the multiple materialities of Hoodia illuminates the connections between law, science, and the marketplace, while demonstrating how these domains value certain forms of knowledge and matter differently.
