Dave Borlace delivers a startling revelation that reframes the global water crisis not as a shortage of rain, but as a crisis of dietary choice. While most discussions focus on drought or infrastructure, Borlace forces a confrontation with the hidden hydrological cost of modern meat consumption, arguing that our current agricultural trajectory is mathematically incompatible with a nine-billion-person planet. This is not just an environmental plea; it is a hard look at the physics of feeding humanity without draining the planet dry.
The Hidden Hydrology of Dinner
Borlace anchors his argument in the stark reality of the hydrological cycle, reminding us that the water on Earth is finite. "The water that was shared between 1.5 billion people about a hundred years ago is the same amount of water that was shared between three point six billion people fifty years later," he writes, highlighting that the resource pool has not expanded despite the population explosion. This framing is effective because it strips away the illusion of abundance; we are not running out of water, we are simply trying to stretch a fixed amount across an ever-widening demand.
The author then pivots to the specific mechanics of how we use this water, moving from abstract cycles to the tangible reality of a family barbecue. He illustrates the staggering disparity between direct human consumption and the "hidden water" embedded in food production. "To produce a kilogram of steak... takes fifteen thousand five hundred liters of water," Borlace notes, a figure that dwarfs the 380 liters used by his entire household for a week. The visual of filling a 1,000-liter tote container to represent the water in a single kilo of beef makes the abstract data visceral and immediate.
Ninety-seven point five percent of the world's water is in the oceans and of course that water is salty and undrinkable without significant energy hungry industrial manipulation.
This statistic serves as the foundation for his critique of current agricultural practices. Borlace argues that while regenerative agriculture offers a path to restore soil health and water retention, the global food system is optimized for something else entirely. "Most of our food production is focused solely on maximizing crop yield and monetary profit with very little focus on soil health carbon retention and water levels," he observes. This is a crucial distinction: the problem isn't a lack of technology, but a misalignment of incentives. The system is designed to extract maximum calories and profit, often at the expense of the very water tables that sustain it.
Critics might argue that shifting away from meat is a privilege of the wealthy and that developing nations need affordable protein to lift populations out of poverty. Borlace acknowledges this tension, noting that rising incomes in places like China have led to a surge in meat consumption as a marker of prosperity. However, he counters that the current trajectory is unsustainable, warning that "by 2030... the demand from water will be 40 percent higher than all of the available fresh water on the planet."
The Land Use Paradox
The commentary deepens as Borlace examines the inefficiency of land use. He points out a profound irony: we are dedicating the vast majority of our arable land to livestock, which in turn provides a minority of our calories. "Seventy-seven percent is used for livestock and only 23 percent for human consumption crops," he states, yet the livestock sector yields "only 17 percent of the total calorific supply to humans." This data exposes a massive inefficiency in the global food supply chain that goes largely unaddressed in mainstream policy debates.
The author connects this inefficiency to the broader climate crisis, explaining how rising temperatures exacerbate water scarcity even as the atmosphere holds more moisture. "For every one degree Celsius of warming our atmosphere holds 7 percent more moisture," Borlace explains, yet this leads to more extreme flooding rather than wetter soil. The water hits "rock hard dried-up earth and runs off taking any topsoil nutrients with it," creating a vicious cycle of desertification and flood. This analysis effectively bridges the gap between climate change and food security, showing that they are not separate issues but two sides of the same coin.
The real issue that our growing population faces is the amount of so-called hidden water required to grow all the food that our modern societies demand.
Borlace concludes by suggesting that the solution lies in a fundamental shift toward regenerative practices that work with nature rather than against it. He highlights the potential of reforestation and soil regeneration to turn land into a sponge, capable of holding water and sequestering carbon. "Regenerative agriculture is not how we currently feed the majority of people on our planet," he admits, but implies it is the only viable path forward. The argument is compelling because it offers a concrete mechanism—soil health—to solve a seemingly intractable resource problem.
Bottom Line
Borlace's strongest contribution is his ability to translate complex hydrological data into a simple, undeniable equation: the current meat-heavy diet is a mathematical impossibility for a growing global population. The argument's vulnerability lies in the political and cultural inertia required to shift global dietary habits, a challenge he identifies but cannot fully solve. Readers should watch for how this data influences future agricultural policy and whether the push for regenerative farming can overcome the entrenched economic models of industrial livestock production.
