If you care about people, you must care about what we are doing to the planet. If you care about what we are doing to the planet, you must also care about human numbers. Given a planet with infinite space and resources, population growth could, arguably, be a blessing. We do not live on such a planet. However, there was a time when the Earth and its resources appeared boundless. Some people still adhere to that anachronistic belief. If nothing else, the photographs in this book should shatter that illusion.
Given the central role that population dynamics will play in determining the welfare of future generations, what the world needs today is a wake-up call. This book is that wake-up call. The photographs to follow are emotionally jarring; they are deeply provocative. But that is the nature of wake-up calls. The way that human numbers and behavior are transforming the Earth, undermining its ability to support the human family and the rest of life, is apparent for all to see. The reality of this urgent moment calls us to think, to care, and to act.The photographs are, to be sure, truly amazing and disturbing. But the story is exactly the same one that I have been telling in my book (see especially Chapter 11) for a long time. Indeed, this book--either the published version (coffee table style) or the free online version (slide show style)--should be required reading not only for every student reading my Population text, but for every human now alive.
