We have 118 known chemical elements as our palette in our context of sustaining our world. Our context is considered in terms of the four spheres of the ancient world: Earth, Air, Fire and Water. This book shows how chemical principles can be used to understand the pressures on our world, spanning from greenhouse emissions through freshwater supplies to energy generation and storage. The supply of the chemical elements is key to their contribution to alleviating these pressures. Most synthetic and radioactive elements are not available in sufficient supply to contribute in this. Some solutions, such as wind turbines, batteries, fuel cells and automotive exhaust remediation pose questions about sustainable supplies of critical elements. With an eye on the target of the IPCC of capping the temperature anomaly to 1.5 oC (RCP2.6), options for carbon capture and storage, and the generation of energy and element supply from the sea are assessed. The consequences of the escape of plastics and pharmaceuticals into the wider environment for water integrity are also considered. This book is designed around providing a one semester course for students who have entered at least the second level of university chemistry. It provides explanations and entries to current environmental issues. For students of environmental science, it provides an understanding of the chemical principles underpinning the causes and possible solutions to these issues. Each chapter has a set appropriate study questions. A study guide is available for the book. -- Provided by publisher.

For decades, the debate on human gene-editing has identified and agreed upon certain limits that draw the line between ethical and unethical territory: for example, applications for diseases are accepted, but not for enhancements. However, society keeps pushing the limits, as seen with the advent of CRISPR technology and the birth of the first genetically modified babies in China. John H. Evans rethinks how we discuss and debate these collective limits, which have long been characterized as a slippery slope. He examines past, present, and future arguments, and argues which limits can hold and which cannot, before we reach the dystopian bottom.
