Nature Is Thriving Yet Collapsing at the Same Time

Nature Is Thriving Yet Collapsing at the Same Time

Here is a paradox you can hold in your hands: humanity has never extracted more from nature than it does right now. Global food production has doubled since the 1970s. Timber harvests are at an all time high. We pull more fish from the ocean, more minerals from the earth, more fresh water from rivers than any generation before us. By the raw metrics of resource extraction, nature is performing miracles.

And yet, according to a landmark 2019 paper in Science by ecologist Sandra Díaz and 33 coauthors, the fabric of life on Earth is unravelling faster than at any point in human history (Díaz et al., 2019). The same systems that are producing more food, more fiber, more fuel than ever are simultaneously losing their capacity to sustain themselves. The authors call it a "global collapse of the living world." We are living through a boom and a bust at the exact same time.

How can both things be true? Because we have been counting the wrong things.

What 34 Scientists Found When They Looked at the Whole Planet

The Díaz paper is not a single experiment. It is a synthesis, the kind of work that only becomes possible when you assemble a global team of experts and ask them to step back from their individual plots of data and look at the whole picture. The authors reviewed thousands of studies, analyzed global databases on species abundance, ecosystem extent, and local ecological diversity, and then asked a deceptively simple question: Is nature, on balance, getting better or worse?

The answer depends entirely on what you measure.

If you measure the total amount of biological material that humans harvest, nature is booming. The paper reports that since 1970, the global supply of materials from nature has increased sharply. We are eating more, building more, burning more. The planet's biological productivity is being funneled into human systems at an accelerating rate.

But if you measure the health of the systems that produce those materials, the picture flips. Díaz and her colleagues documented four simultaneous declines that together paint a picture of systemic degradation:

• ▸The extent and integrity of ecosystems have shrunk dramatically. Forests, wetlands, coral reefs, and grasslands have been converted, fragmented, or degraded.
• ▸Local ecological communities are becoming more uniform. Distinct ecosystems are blending into one another as generalist species replace specialists.
• ▸The abundance and number of wild species have dropped. Populations are smaller. Ranges are contracting. Extinctions are accelerating.
• ▸The number of local domesticated varieties of crops and livestock has fallen. We are losing agricultural biodiversity at the same time we lose wild biodiversity.

The authors found that these trends are not independent. They reinforce each other. A forest that has been logged loses its structural complexity, which reduces the number of species it can support, which makes it less resilient to drought or fire, which makes it harder for the forest to regenerate, which means less timber for the next harvest. The system is producing more in the short term by cannibalizing its own future capacity.

Why the Boom Cannot Last

Here is the part that surprised me. The Díaz paper shows that the relationship between human well being and nature's health is not a simple trade off. It is a trap.

For most of human history, we could increase our harvest from nature without permanently damaging the systems that produced those harvests. We cut down a forest, it grew back. We fished a stock, it replenished. That was the implicit assumption behind centuries of resource management: nature is resilient, and if we are careful, we can have both growth and stability.

But the authors document that we have passed a threshold. The demands we place on nature now exceed its capacity to regenerate. We are not just harvesting interest from the natural world. We are eating the principal.

Consider the numbers. The paper reports that the human population has doubled since 1970, and per capita consumption has risen even faster. To meet those demands, we have converted roughly 75 percent of the Earth's land surface and 66 percent of its marine environment. We have altered the planet so thoroughly that scientists now argue we have entered a new geological epoch, the Anthropocene. But the Díaz paper adds a chilling detail: the very changes that have allowed us to extract more from nature have also made the remaining natural systems more fragile. We have simplified ecosystems to make them more productive, and in doing so we have made them less stable.

A wheat field produces more food per acre than a prairie. But a wheat field can be wiped out by a single pathogen or a single drought. A prairie cannot. The resilience is gone.

Who Pays for the Collapse

The Díaz paper is not an abstract environmental lament. It is a distributional analysis. The authors are explicit: the benefits of nature's exploitation and the costs of its decline are not shared equally.

The benefits flow upward. Wealthier nations and wealthier individuals consume far more of nature's resources than poorer ones. The average American or European uses dozens of times more materials than the average person in sub Saharan Africa. The economic growth that has lifted billions out of poverty has been fueled by the extraction of natural resources, but the extraction has been concentrated in specific regions, often in the Global South.

The costs flow downward. When ecosystems collapse, the people who suffer most are those who depend directly on nature for their daily survival. Subsistence farmers, indigenous communities, coastal fishers. These are people who cannot simply buy their way out of a failed crop or a depleted fishery. They are the first to feel the consequences of a world where nature is supplying more materials than ever but is less able to provide the basic services that sustain life: clean water, fertile soil, stable climate, pollination.

The authors found that the decline of nature's contributions to people is already reducing quality of life for billions of people, and the effects are projected to worsen for future generations. This is not a future problem. It is a present one.

What the Paper Does Not Prove

The Díaz paper is rigorous, but it has limits. The authors are careful to note that their synthesis relies on existing data, and the data are uneven. We have good records for some regions and some species, poor records for others. The tropics are understudied. So are the deep oceans. So are soil ecosystems, which contain much of the planet's biodiversity but are almost invisible to us.

The paper also does not prove that collapse is inevitable. The authors describe trajectories, not destinies. They document what is happening now and what is likely to happen if current trends continue. But they also point to opportunities for transformative change. The word "transformative" appears repeatedly in the paper, and it is not rhetorical. The authors mean something specific: incremental adjustments will not work. The scale and speed of the changes required are unprecedented. But they are possible.

The open question, which the paper does not answer, is whether the political and economic systems that created this crisis can also solve it. The authors call for addressing the "root economic, social, and technological causes" of nature's deterioration. That is a polite way of saying that the same structures that have produced the boom are also producing the collapse. Changing those structures is not a technical problem. It is a political one.

The Uncomfortable Truth About Efficiency

One of the most unsettling implications of the Díaz paper is that efficiency is not the solution. For decades, environmentalists have argued that we need to use nature more efficiently. Produce more food per acre. Catch more fish per boat. Extract more timber per hectare. The logic is simple: if we can get more output from less input, we reduce pressure on ecosystems.

But the Díaz paper suggests that efficiency, by itself, can backfire. When we become more efficient at extracting resources from nature, we lower the cost of those resources, which encourages more consumption. This is the Jevons paradox, named for the 19th century economist who noticed that more efficient coal engines led to more coal burning, not less. The same dynamic applies to nature. More efficient agriculture has not spared land for wilderness. It has allowed us to convert even more land to agriculture. More efficient fishing has not allowed fish stocks to recover. It has allowed us to fish them down to lower levels.

The authors do not argue that efficiency is bad. They argue that efficiency without limits is dangerous. If we do not also constrain total consumption, efficiency becomes a tool for accelerating the collapse.

What This Actually Means

• ▸Stop counting what we take and start counting what we keep. Most economic indicators measure extraction. GDP goes up when we cut down a forest. It does not go down when the forest fails to regrow. The Díaz paper shows that we need a different set of metrics, one that tracks the health of ecosystems themselves, not just their outputs.

• ▸The next wave of environmental policy must address consumption, not just production. For decades, the focus has been on making production cleaner and more efficient. That is necessary but not sufficient. The authors make clear that reducing total demand for natural resources is the only path that does not end in collapse.

• ▸Equity is not a side issue. It is the central issue. The benefits of extraction and the costs of collapse are distributed in opposite directions. Any solution that does not address this asymmetry will fail, because the people who benefit most from the current system have the most power to maintain it.

• ▸Transformative change means changing the rules of the economy, not just tweaking them. The Díaz paper calls for addressing root causes. That means questioning assumptions about growth, consumption, and property that have been treated as natural laws. They are not laws. They are choices.

• ▸The window for action is narrow but not closed. The authors are clear: the situation is dire, but it is not hopeless. The changes required are large, but they are known. The question is whether we will make them in time. The answer is not written yet.
