Discover the extreme facts about technology in this kooky book"--.

"From healing to astronomy to our connection to the natural world, the lessons from Indigenous knowledge inform our learning and practices today. How do knowledge systems get passed down over generations? Through the knowledge inherited from their Elders and ancestors, Indigenous Peoples throughout North America have observed, practiced, experimented, and interacted with plants, animals, the sky, and the waters over millennia. Knowledge keepers have shared their wisdom with younger people through oral history, stories, ceremonies, and records that took many forms. . . Eldon Yellowhorn and Kathy Lowinger reveal how Indigenous knowledge comes from centuries of practices, experiences, and ideas gathered by people who have a long history with the natural world. Indigenous knowledge is explored through the use of fire and water, the acquisition of food, the study of astronomy, and healing practices"--Provided by publisher.

"An essential analysis of the modern science and technology that makes our twenty-first century lives possible--a scientist's investigation into what science really does, and does not, accomplish. We have never had so much information at our fingertips and yet most of us don't know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its future, How the World Really Works offers a much-needed reality check--because before we can tackle problems effectively, we must understand the facts. In this ambitious and thought-provoking book we see, for example, that globalization isn't inevitable--the foolishness of allowing 70 per cent of the world's rubber gloves to be made in just one factory became glaringly obvious in 2020--and that our societies have been steadily increasing their dependence on fossil fuels, such that any promises of decarbonization by 2050 are a fairy tale. For example, each greenhouse-grown supermarket-bought tomato has the equivalent of five tablespoons of diesel embedded in its production, and we have no way of producing steel, cement or plastics at required scales without huge carbon emissions. Ultimately, Smil answers the most profound question of our age: are we irrevocably doomed or is a brighter utopia ahead? Compelling, data-rich and revisionist, this wonderfully broad, interdisciplinary guide finds faults with both extremes. Looking at the world through this quantitative lens reveals hidden truths that change the way we see our past, present and uncertain future"--.
