Overdevelopment, Overpopulation, Overshoot

"Every major problem facing humanity is exacerbated by a needlessly ballooning human population. So why is the explosive growth of the human family--more than sevenfold since the Industrial Revolution and still expanding rapidly--generally ignored by policy makers and the media? And why has the environmental movement chosen to be mostly silent about the fundamental driver of species loss and the destruction of wildlife habitats around the globe? Isn't it time to start speaking out about the equation that matters most to the future of people and the planet? The publication centerpiece of the Global Population Speakout campaign, Overdevelopment, Overpopulation, Overshoot ("OVER") moves beyond insider debates and tired arguments (human numbers and overconsumption are both responsible for the crisis of population overshoot). Anchored by a series of provocative photo essays, OVER presents the stark reality of a world transformed by human action, action that threatens our future and the buzzing, blossoming diversity of life with which we share the planet."--Publisher website.
