About this book
New edition of this popular textbook covering the natural environments and how they function. It provides concise, non-technical explanations of physical processes and systems and the effects human activities have upon them. Environmental issues included are global warming, genetically modified foods, desertification, acid rain, deforestation, human population growth, and nuclear power generation.
Part 1 Introduction: what is environmental science?; environmental interactions, cycles and systems; ecology and environmentalism; history of environmental science; changing attitudes to the natural world.

Part 3 Physical resources: fresh water and the hydrological cycle; eutrophication and the life cycles of lakes; salt water, brackish water, and desalination; irrigation, waterlogging, and salinization; soil formation, ageing, and taxonomy; transport by water and wind; soil, climate, and land use; soil erosion and its control; mining and processing of fuels; mining and processing of minerals. Part 4 Biosphere: biosphere, biomes, biogeography; nutrient cycles; respiration and photosynthesis; trophic relationships; energy, numbers, biomass; ecosystems; succession and climax; arrested successions; colonization; stability, instability, and reproductive strategies; simplicity and diversity; homeostasis, feedback, regulation; limits of tolerance.
