Understanding how the commodification of water has contributed to global water scarcity

Explore an interactive map of global water gaps, caused by demand surpassing replenishment

Humans extract 4,000 cubic kilometers of water from natural systems annually—eight times more than a century ago—creating regions where freshwater demand surpasses available reserves. The depletion of shallow aquifers has driven tapping into deeper, nonrenewable ones, threatening ecosystem sustainability.

A breakdown of where water is located on Earth and where it is most used worldwide

About 97% of Earth's water volume is in the oceans, 2% is trapped in polar ice caps and glaciers, and almost all of the remaining 1% is found in groundwater reserves. Roughly 70% of the easily accessible surface water in rivers and lakes—0.01% of all water—is used for agriculture, contributing to 20% of the world's population living in water-scarce areas and 2.1 billion people lacking access to clean drinking water.

Desalination involves costly, energy-intensive methods for producing freshwater

Thermal desalination heats saltwater to produce steam, and reverse osmosis forces saltwater through a membrane that only allows water through. In both cases, freshwater is collected and remineralized for consumption, while wastewater brine is often returned to the ocean, where it may harm marine organisms.

Local governments are responsible for more than 148,000 public water systems across the US

A chemical overview of water, whose uncommon properties help sustain life on Earth

The uneven distribution of charge in water molecules allows them to bond to each other and to surfaces, enabling them to move against gravity, including up plants through roots and stems. These bonds also keep water in a liquid state over a wider temperature range and make it less dense as it freezes. This causes ice to float and form an insulating layer for underwater ecosystems, from which all life originated.

Technologies developed for the ISS have brought benefits to people on Earth

About 93% of water used onboard the International Space Station is recycled through filtration and purification systems that have since been used in regions lacking access to clean water. Treatments to mitigate bone loss and muscle atrophy in astronauts can also help aging adults.

Over time, the World Cup became a commercial powerhouse

The 1954 World Cup featured the first live black-and-white televised broadcast of the event, and, in 1970, FIFA introduced color broadcasts in primetime. Increasing revenues pushed private networks to aggressively bid for broadcast rights. Today, the event is a commercial powerhouse, with the 2026 World Cup projected to generate around $4B in TV rights revenue.

Why caviar is still so expensive, even though it's no longer rare

An ounce of caviar can cost more than $250, even though China has flooded the market with a surge in supply over the past decade. As it turns out, the perception of caviar as a luxury good rather than a true scarcity is part of what keeps it so expensive.

Why content disappears from streaming services

The early days of streaming suggested we'd have access to all the world's content whenever we wanted.

It's tough to measure just how much the global commodities market is worth

That's partly because of all the different ways and places commodities are traded—such as futures exchanges, spot markets, and over-the-counter deals.
