Full Planet, Empty Plates: Chapter 2. The Ecology of Population Growth

Throughout most of human existence, population growth has been so slow as to be imperceptible within a single generation. Reaching a global population of 1 billion in 1804 required the entire time since modern humans appeared on the scene. To add the second billion, it took until 1927, just over a century. Thirty-three years later, in 1960, world population reached 3 billion. Then the pace sped up, as we added another billion every 13 years or so until we hit 7 billion in late 2011.

The New Global Food Crisis: Lester Brown’s Full Planet, Empty Plates

The phrase “global food crisis” may strike us in the developed world as a bit overblown. But in his new book Full Planet, Empty Plates: The New Geopolitics of Food Scarcity, Lester R. Brown, founder of the Earth Policy Institute, aptly demonstrates that our current food security situation is anything but normal… and could even represent the “weak link” to maintaining the standard of living to which we’ve become accustomed.

Redefining Security for the 21st Century

The situation in which we find ourselves pushes us to redefine security in twenty-first century terms. The time when military forces were the prime threat to security has faded into the past. The threats now are climate volatility, spreading water shortages, continuing population growth, spreading hunger, and failing states. The challenge is to devise new fiscal priorities that match these new security threats.

Troubling Health Trends Holding Back Progress on Life Expectancy

People born today will live for 68 years on average, 20 years longer than those born in 1950. By the mid-twentieth century, industrial countries had already made major strides in extending lifespans with improvements in sanitation, nutrition, and public health. After World War II, rapid gains in life expectancy in developing countries began to narrow the gap between these nations and industrial countries. Although average life expectancy worldwide continues to increase, gains have come more slowly in the last few decades. Worryingly, life expectancy has actually declined in some developing countries, while a few industrial countries have stalled or made slow progress on this important indicator of human health and well-being.
