GR: Around 25,000 participants and observers from 164 countries agreed to ask the UN to emphasize biodiversity as an essential component of sustainable development. Then everyone shut their eyes, patted herself or himself on the back, and went home to continue business as usual: Growth.

Half a century ago, Garrett Hardin commented that “sustainable growth” is an oxymoron. The participants in the CBD should be reading Hardin. Here’s a quote from a tribute to Hardin by John Cairns (2004: http://bit.ly/1wfC8Ii) that relates to one of the CBD’s recommendations (the biobridge).

“He (Hardin) was a strong supporter of and commentator on Kenneth Boulding’s dismal and utterly dismal theories of economics. The dismal theory states that, if the only check on the growth of population is starvation and misery, then no matter how favorable the environment or how advanced the technology, the population will grow until it is miserable and starves. The utterly dismal theory states that, if the only check on population growth is starvation and misery, then any technological improvement will have the ultimate effect of increasing the sum of human misery since it permits a larger population to live in precisely the same state of misery and starvation as before the change. Although Boulding first proposed both these theories in 1956 and Hardin reinforced them in 1968, the dangerous expectation still exists that a technological solution can be found to every problem.”

Feeding 3 Billion More People

The U. S. Census Bureau uses world data to estimate that in 2150, Earth’s human population will reach 9 billion and stay around that number for the next few centuries. But must we stop? Can’t we go on to 12 billion? In an article published in America’s leading academic journal, Science, a group of scientists led by Paul C. West say yes. Here is the full abstract of their article:

“Achieving sustainable global food security is one of humanity’s contemporary challenges. Here we present an analysis identifying key “global leverage points” that offer the best opportunities to improve both global food security and environmental sustainability. We find that a relatively small set of places and actions could provide enough new calories to meet the basic needs for more than 3 billion people, address many environmental impacts with global consequences, and focus food waste reduction on the commodities with the greatest impact on food security. These leverage points in the global food system can help guide how nongovernmental organizations, foundations, governments, citizens’ groups, and businesses prioritize actions” (Paul C. West, et al, Science 345: 325-328).

The editors of Science had this to say: “Keeping societies stable and managing Earth’s resources sustainably depend on doing a good, steady job producing and distributing food. West et al. asked what combinations of crops and regions offer the best chance of progress. Their analysis focused on reducing greenhouse gas emissions, nutrient pollution, water use, and food waste. They identify regions that are likely to yield the best balance between applying fertilizer to increase crop yields versus the resulting environmental impact” (editor, Science 345: 325).

Of course, there will be problems finding the leadership needed to pull the levers the authors identify. If we can find them, however, perhaps we can then begin looking for more solutions that will let us sustain our growth far into the future. Some pessimists have pointed out that we can’t keep growing because we would eventually reach the point where we would shoulder-to-shoulder cover the planet. Well, we have learned it is possible to live and reproduce in tight spaces. Besides, what about adapting to living standing on someone’s shoulders (or being stood upon)? We could double the bleaker’s so-called space limitation.

New Housing With Uncertain Water Supplies

Despite the uncertainties, the effort of Paul C. West his coauthors should encourage renewed efforts by developers who might have felt a tingle of concern that growth and profits could slow. Their new slogan might become: “Don’t say slow, science says grow.” ;-).
