Beyond 7 billion

An interesting series by the LA Times about population growth and its challenges. After remaining stable for most of human history, the world’s population has exploded over the last two centuries. The boom is not over: The biggest generation in history is just entering its childbearing years. The coming wave will reshape the planet, and the impact will be greatest in the poorest, most unstable countries.

Urbanization Is Not the Problem (Dealing With It Is)

While the rest of the world is urbanizing, Latin America is urbanized. The region has four of the world’s 19 megacities (cities with populations over 10 million people) and 78% of all its people currently live in urban areas. Latin America’s concerns over urbanization, therefore, are based on the substantial amount of people currently in cities as opposed to the anticipation of populations to come. For example, of the one billion increase cities will experience by 2025, the United Nations estimates Latin America will only add about 127 million to its population. This is not insignificant for sure, but the slower rate of urbanization does change the nature in which urban planning occurs.

Looking Back on the Limits of Growth

Recent research supports the conclusions of a controversial environmental study released 40 years ago: The world is on track for disaster. So says Australian physicist Graham Turner, who revisited perhaps the most groundbreaking academic work of the 1970s,The Limits to Growth.

Written by MIT researchers for an international think tank, the Club of Rome, the study used computers to model several possible future scenarios. The business-as-usual scenario estimated that if human beings continued to consume more than nature was capable of providing, global economic collapse and precipitous population decline could occur by 2030.

However, the study also noted that unlimited economic growth was possible, if governments forged policies and invested in technologies to regulate the expansion of humanity’s ecological footprint. Prominent economists disagreed with the report’s methodology and conclusions. Yale’s Henry Wallich opposed active intervention, declaring that limiting economic growth too soon would be “consigning billions to permanent poverty.”

Turner compared real-world data from 1970 to 2000 with the business-as-usual scenario. He found the predictions nearly matched the facts. “There is a very clear warning bell being rung here,” he says. “We are not on a sustainable trajectory.”
