"In spite of 50 years of the fastest population growth on record, the world did remarkably well in producing enough food and reducing poverty," said University of Michigan economist David Lam, in his presidential address at the annual meeting of the Population Association of America. Lam is a professor of economics and a research professor at the U-M Institute for Social Research. The talk is titled "How the World Survived the Population Bomb: Lessons from 50 Years of Exceptional Demographic History." In 1968, when Paul Ehrlich's book, "The Population Bomb," triggered alarm about the impact of a rapidly growing world population, growth... More »

Scientists call the plant "supply" net primary production, or NPP, and refer to the "demand" as Human Appropriation of Net Primary Production (HANPP). We may be becoming an ever more technologically advanced society, but we remain as dependent as ever -- if not more and more so -- on the natural world that surrounds us. That is one takeaway from new NASA research that has found humans are using an increasing amount of the Earth's total land plant production each year for food, fiber, building and packaging materials and biofuels. This remains a young data record, as one of the first global measurements tied to... More »
