Revisiting population growth: The impact of ecological limits

Demographers are predicting that world population will climb to 10 billion later this century. But with the planet heating up and growing numbers of people putting increasing pressure on water and food supplies and on life-sustaining ecosystems, will this projected population boom turn into a bust?

Jeremy Rifkin: The Third Industrial Revolution

The world is doomed to repeat four-year cycles of booms followed by crashes if we don’t get off oil, Jeremy Rifkin warned a Climate One audience in San Francisco on October 3. The solution, what he calls the Third Industrial Revolution, is the “Energy Internet,” a nervous system linking millions of small renewable energy producers.

The new recession

We’re at the end of growth. Growth of the economy, of consumption, of wealth. That this would happen isn’t news to those who’ve followed the writings of Meadows, Heinberg, and many others. What’s different now is that it may have actually arrived. I’d like to briefly look at our current situation in this context and synthesize the various ideas we explored in previous posts.

Sustainable shrinkage: envisioning a smaller, stronger economy

More than two decades after the Brundtland Report, it’s past time to abandon this linguistic sleight of hand and rally around a new, shocking but this time realistic slogan: sustainable shrinkage! Within this new perspective, we can get on with saving species, restoring wastelands, improving efficiency, putting our life-support systems on sustainable bases—in short, finding solutions. But we’ll do so with a new urgency and clarity, conscious that if we are to survive on our little planet in some reasonably civilized way, human activity (and its impacts) must shrink. If we don’t shrink it, Gaia will shrink it for us, catastrophically.

European debt crisis and sustainability

Humans seem to be reaching a new bottleneckrelated to oil limits and financial crises that grow out of these oil limits, with the current example being the European Debt Crisis. Depending how this and other debt crises work out, it seems possible that human population will decline. If this should happen, it could lead to a reduced problem with species extinction.

Cassandra’s curse: how “The Limits to Growth” was demonized

There is a legend lingering around the first “Limits to Growth” book that says that it was laughed off as an obvious quackery immediately after it was published. It is not true. The study was debated and criticized, as it is normal for a new theory or idea. But it raised enormous interest and millions of copies were sold. Evidently, despite the general optimism of the time, the study had given visibility to a feeling that wasn’t often expressed but that was in everybody’s minds. Can we really grow forever?
