Ecologists worry that the world’s resources come in fixed amounts that will run out, but we have broken through such limits again and again

How many times have you heard that we humans are “using up” the world’s resources, “running out” of oil, “reaching the limits” of the atmosphere’s capacity to cope with pollution or “approaching the carrying capacity” of the land’s ability to support a greater population? The assumption behind all such statements is that there is a fixed amount of stuff—metals, oil, clean air, land—and that we risk exhausting it through our consumption.
“We are using 50% more resources than the Earth can sustainably produce, and unless we change course, that number will grow fast—by 2030, even two planets will not be enough,” says Jim Leape, director general of the World Wide Fund for Nature International (formerly the World Wildlife Fund).
But here’s a peculiar feature of human history: We burst through such limits again and again. After all, as a Saudi oil minister once said, the Stone Age didn’t end for lack of stone. Ecologists call this “niche construction”—that people (and indeed some other animals) can create new opportunities for themselves by making their habitats more productive in some way. Agriculture is the classic example of niche construction: We stopped relying on nature’s bounty and substituted an artificial and much larger bounty.
Economists call the same phenomenon innovation. What frustrates them about ecologists is the latter’s tendency to think in terms of static limits. Ecologists can’t seem to see that when whale oil starts to run out, petroleum is discovered, or that when farm yields flatten, fertilizer comes along, or that when glass fiber is invented, demand for copper falls…
…Until about 10 years ago, it was reasonable to expect that natural gas might run out in a few short decades and oil soon thereafter. If that were to happen, agricultural yields would plummet, and the world would be faced with a stark dilemma: Plow up all the remaining rain forest to grow food, or starve.
But thanks to fracking and the shale revolution, peak oil and gas have been postponed. They will run out one day, but only in the sense that you will run out of Atlantic Ocean one day if you take a rowboat west out of a harbor in Ireland. Just as you are likely to stop rowing long before you bump into Newfoundland, so we may well find cheap substitutes for fossil fuels long before they run out…

…Developed primarily for the Israel Defense Forces (IDF), Water-Gen says it has already sold units to militaries in seven countries, but Kohavi is keen to stress that the general population can also benefit from the technology.
He explains: “We believe that the products can be sold to developing countries in different civilian applications. For example in India, [drinking] water for homes is not available and will also be rare in the future. The Atmospheric Water-Generation Unit can be built as a residential unit and serve as a perfect water supply solution for homes in India.”
Kohavi says Water-Gen’s units can produce a liter of water for 1.5 Rupees, as opposed to 15 Rupees for a liter of bottled water…
