Welcome to Terra Incognita. Based on decades of research, and combining mesmerising, state-of-the-art satellite maps with enlightening and passionately argued analysis, Ian and Robert chart humanity's impact on the planet, and the ways in which we can make a real impact to save it, and to thrive as a species. Learn about: fires in the arctic; the impact of sea level rise on cities around the world; the truth about immigration - and why fears in the West are a myth; the counter-intuitive future of population rise; the miracles of health and education that are waiting around the corner, and the reality about inequality, and how we end it. The book traces the paths of peoples, cities, wars, climates and technologies, all on a global scale. Full of facts that will confound you, inform you, and ultimately empower you, Terra Incognita guides readers to a new place of understanding, rather than to a physical location.
