Earth’s natural resources are being consumed faster than they can regenerate, and the trend is accelerating. Between 1970 and 2024, the total weight of materials humans extract from the planet each year jumped from 30 billion metric tons to 106.6 billion metric tons. That includes everything from timber and crops to fossil fuels, metals, and sand. Forests, freshwater, fisheries, and biodiversity are all under mounting pressure, and the demands we place on these systems are projected to grow sharply by mid-century.
Forests Are Disappearing at Record Speed
Tropical forests took the hardest hit in recent years. In 2024, the tropics lost a record 6.7 million hectares of primary rainforest, an area nearly the size of Panama. That works out to roughly 18 football fields of old-growth forest vanishing every minute, nearly double the rate from the previous year. Brazil remains the single largest contributor, accounting for 42% of all tropical primary forest loss. Bolivia has surged to second place.
Within Brazil, the Pantanal wetland lost 1.6% of its total tree cover in a single year, more than double the national average. Fire was a major driver of the 2024 spike, turning what had been a slow, grinding problem into something far more dramatic. These aren’t tree plantations being cleared and replanted. Primary rainforest is irreplaceable on any human timescale. Once it burns or gets cut, the dense biodiversity and carbon storage it provided take centuries to rebuild, if they come back at all.
Freshwater Supplies Are Shrinking Underground
The water crisis is largely invisible because much of it is happening beneath our feet. A major analysis of 170,000 monitoring wells across 1,693 aquifer systems found that rapid groundwater declines (more than half a meter per year) are widespread in the 21st century. The steepest drops are concentrated in dry regions with extensive cropland, where farmers pump groundwater faster than rain can replenish it.
Perhaps more troubling than the current levels is the direction of change. In 30% of the world’s regional aquifers, the rate of decline has accelerated over the past four decades. Groundwater isn’t just drinking water. It feeds rivers during dry seasons, sustains wetlands, and irrigates crops that billions of people depend on. When an aquifer drops below a usable depth, the communities above it face a problem that no short-term fix can solve.
By 2050, worldwide water demand is projected to increase by 20 to 30 percent. The share of the global population experiencing water stress for at least one month per year is expected to rise from roughly one-third today to 58%, affecting up to 5.7 billion people.
Species Are Vanishing at an Unprecedented Rate
An estimated one million animal and plant species are currently threatened with extinction, according to the most comprehensive global biodiversity assessment ever conducted. That figure, from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, represents a scale of loss with no precedent in human history.
Earlier waves of human-caused extinction mostly hit especially vulnerable species: flightless birds on islands, large mammals with slow reproductive rates. What’s different now is the breadth. Habitat destruction, pollution, climate change, and overexploitation are pushing a far wider range of species toward collapse. Scientists involved in the assessment have described past losses as “a small ripple compared to the tsunami” that will follow if the underlying drivers aren’t addressed. When species disappear, so do the ecosystem services they support: pollination, pest control, water filtration, soil health.
Six of Nine Planetary Safety Limits Are Crossed
Scientists have identified nine planetary boundaries, thresholds that define a safe operating space for human civilization. As of the most recent assessment, six of those nine have been breached. The boundaries already crossed include climate change, land system change (deforestation and land conversion), freshwater use, biodiversity loss, the flow of nitrogen and phosphorus into ecosystems, and the release of synthetic chemicals into the environment.
Ocean acidification is close to being breached. Air pollution from fine particles already exceeds the boundary in some regions. For every boundary that was previously identified as overstepped, the level of transgression has increased, meaning the situation is getting worse, not stabilizing. The chemical pollution boundary is particularly striking: so many untested synthetic compounds are now entering the environment that researchers concluded the safe limit is clearly exceeded, even though they can’t yet put a precise number on the threshold.
Material Extraction Has More Than Tripled
The sheer volume of stuff humans pull from the Earth has grown at an average rate of 2.3% per year since 1970. At 106.6 billion metric tons annually, that figure includes four main categories: biomass (crops, timber, fish), fossil fuels (coal, oil, gas), metal ores, and non-metallic minerals (sand, gravel, limestone). Sand alone is now the most extracted solid material on the planet after water, driven by concrete production in rapidly urbanizing countries.
This isn’t just about running out of a particular material. Extraction reshapes landscapes, pollutes waterways, destroys habitats, and generates enormous quantities of waste. Every ton of copper ore mined, for example, yields only a small fraction of usable metal. The rest becomes tailings that must be stored indefinitely.
Demand Is Set to Climb Steeply by 2050
The pressures on natural resources are running headlong into rising demand. World Bank projections estimate that by 2050, food demand will increase by more than 50% over 2010 levels, with demand for animal-based foods specifically rising by 70%. Global energy for transportation is expected to increase by 80 to 130%, and gross electricity consumption could more than double. More than two-thirds of the world’s population will live in cities by then, concentrating demand for water, energy, and building materials in dense urban areas.
These aren’t abstract forecasts. They reflect population growth, rising incomes in developing economies, and urbanization patterns already well underway. The gap between what the planet can sustainably provide and what humanity plans to consume is widening in almost every category simultaneously.
The Economic Costs Are Already Measurable
Degraded natural resources carry a direct economic price tag. In Central America alone, the decline of forest ecosystem services (carbon storage, climate regulation, water cycling) is projected to cost between $51 billion and $314 billion per year through the end of the century. For some lower-middle-income countries in the region, those losses could reach up to 335% of their current GDP, a figure that would fundamentally reshape their economies.
These numbers capture only one region and one type of ecosystem. Globally, the costs of soil degradation, collapsing fisheries, water shortages, and pollinator loss are harder to total but clearly enormous. Natural resources aren’t just raw materials for industry. They provide services, from filtering air to regulating floods, that would cost trillions to replace with engineered alternatives, if replacement were even possible.
