There is a number that should be on the front page of every newspaper in the world. Between 1970 and 2020 — in just fifty years, within a single human lifetime — the average size of monitored wildlife populations on this planet shrank by 73%.

Not 73% of species went extinct. The Living Planet Index, which tracks nearly 35,000 population trends across 5,495 species of amphibians, birds, fish, mammals, and reptiles, is measuring something more immediate: average population size. The typical monitored wildlife population today is less than one-third the size it was fifty years ago. Freshwater species are down 85%. Latin American wildlife populations are down 95% — nearly to nothing, within a single human generation.

This is the WWF Living Planet Report 2024. It is not a projection. It is not a worst-case scenario. It is what happened.

Most people, when they hear about biodiversity loss, think of it as a wildlife problem. Sad, perhaps, but separate from their own lives — a matter for conservation charities and nature documentaries, not for someone trying to navigate the ordinary challenges of health, work, family, and meaning. This article is an attempt to dismantle that separation — because it is, the evidence strongly suggests, a dangerous illusion.

Biodiversity is not the background against which human life occurs. It is the infrastructure on which human life depends. The food you eat, the water you drink, the air you breathe, the medicines that heal you, the climate that sustains your agriculture, and the psychological health that comes from connection with living systems — all of these flow from the web of biodiversity that 73% decline is unravelling. Losing wildlife is not a separate problem from losing ourselves. It is, in the most literal biological sense, the same problem.

Biodiversity is a word that is used so frequently that its actual meaning often gets lost. It is worth being precise — because understanding what biodiversity actually is explains why its loss is so consequential.

Biodiversity — biological diversity — refers to the variety of life on Earth at three interconnected levels. Genetic diversity is the variation within species: the range of genetic traits within a population of bees, or rice varieties, or tigers. This internal variation is what allows species to adapt to changing conditions and to resist disease. A population with low genetic diversity is fragile — one pathogen can wipe it out entirely. Genetic diversity is the insurance policy of evolution.

Species diversity is the variety of different species in an ecosystem: the number and types of plants, animals, fungi, bacteria, and other organisms that interact in a given place. This is the dimension most people think of when they think of biodiversity. But species diversity matters not just as a count but as a functional network — each species playing roles (pollinator, predator, decomposer, seed disperser, nitrogen fixer) that the ecosystem depends on. Remove a species and you remove a function. Remove enough functions and the ecosystem changes — sometimes gradually, sometimes catastrophically.

Ecosystem diversity is the variety of different types of ecosystems across the planet: rainforests, coral reefs, grasslands, wetlands, deserts, mangroves, tundra. Each type of ecosystem provides different services, harbours different species assemblages, and responds differently to disturbance. The loss of entire ecosystem types — the 35% decline in global wetlands since 1970, the destruction of old-growth forests, the bleaching of coral reefs — is the most irreversible dimension of biodiversity loss, because ecosystems are not simply the sum of their species but the complex of relationships and historical processes that produced them.

Interconnectedness — The Principle That Biodiversity Embodies

The fundamental insight that biodiversity represents is interconnectedness: the observation that every living thing exists in relationship with every other living thing, directly or through chains of relationships, and that these relationships are not optional features of life but its essential structure. A fig tree and its specific fig wasp pollinator have co-evolved over millions of years — neither can reproduce without the other. A wolf and an elk interact through predation that keeps elk populations in balance with the vegetation — remove the wolf and the elk overpopulate, overgraze, and alter the entire river valley. A mycorrhizal fungus networks the roots of forest trees, transferring nutrients and chemical signals between them — remove the fungus and the forest loses its underground communication system.These relationships are called ecological interdependence — the mutual dependence of species on each other for survival, reproduction, and function. No species, including Homo sapiens, exists outside this web. We are not observers of biodiversity. We are participants in it, dependent on it, and currently dismantling it at a pace that 50 million years of evolutionary history has never seen before from a single cause.

Tipping Points — Why Biodiversity Loss Is Not Linear

One of the most important and least understood features of biodiversity loss is that it does not produce proportionally gradual consequences. Ecological systems have tipping points — thresholds beyond which they undergo rapid, non-linear, often irreversible transitions to different states. A forest that has lost 30% of its tree species may function relatively normally. The same forest at 50% loss may be approaching a tipping point. At 60% loss it might cross the threshold and reorganise into a degraded state — scrubland, or bare earth, or an invasive monoculture — from which recovery to the original forest state may take centuries or may be permanently impossible.

The WWF Living Planet Report 2024 specifically warns that Earth is approaching ‘dangerous tipping points’ in biodiversity and that the next five years will be critical in determining whether these thresholds are crossed. The urgency is not about distant futures. It is about decisions being made right now, in this decade, about land use, agriculture, fishing, and consumption patterns that will determine which side of those tipping points we end up on.

Reason 1: We Lose Our Food — Pollinators Are Disappearing

Here is a fact worth sitting with: more than 75% of the world’s food crops depend on animal pollinators for fertilisation and seed production. Bees, butterflies, moths, beetles, birds, and bats perform pollination services that contribute $235–577 billion annually to global agricultural output (WHO Biodiversity Fact Sheet, 2025; IPBES Pollinator Assessment).

Wild bee populations have declined by 24% globally since 1990 (IPBES, 2019). The causes are well-documented: neonicotinoid pesticides that impair navigation and immune function, habitat loss that removes the wildflower-rich landscapes that support diverse pollinator communities, monoculture agriculture that provides inadequate nutritional variety for pollinators, the Varroa mite that devastates managed honeybee colonies, and climate change that disrupts the synchronisation between flowering times and pollinator emergence.

The agricultural consequences are already visible. Yields of pollination-dependent crops are declining in regions where pollinator populations have crashed. In parts of China’s Sichuan province, where wild bees have been locally eliminated by pesticide use and habitat destruction, farmers now hand-pollinate apple and pear trees — a process that is labour-intensive, expensive, and incapable of scaling to meet global food demand. This is not a future scenario. It is a current practice in one of the world’s most productive agricultural regions.

For India, pollinator health is directly connected to food security for hundreds of millions of people. India’s vast diversity of wild pollinators — thousands of species of native bees, plus butterflies, moths, and birds — provides pollination services to crops across the subcontinent. The same agricultural intensification, pesticide use, and habitat destruction that is driving global pollinator decline is occurring across Indian agricultural landscapes.

Reason 2: We Lose Our Medicines — The Pharmacy of the Natural World

Over 50% of modern medicines are derived from natural sources — and this statistic, remarkable as it is, understates the pharmaceutical debt that humanity owes to biodiversity. Penicillin and virtually all antibiotics of the pre-synthetic era came from fungi. Morphine and codeine come from the opium poppy. Aspirin was derived from salicylic acid found in willow bark. Taxol — one of the most widely used cancer chemotherapy agents — comes from the Pacific yew tree. Artemisinin — the basis of the most effective malaria treatment currently available — comes from the sweet wormwood plant. Captopril — the first ACE inhibitor, now a cornerstone of hypertension treatment — was developed from the venom of the Brazilian pit viper.

In the developing world, including across most of India, the figure is even higher. The IPBES 2019 assessment identified wild plant and animal species as providing the basis for approximately 70% of medicines used in the developing world. For rural communities with limited access to pharmaceutical supply chains, plant medicines are not a complementary choice — they are the primary healthcare system.

Each species that goes extinct takes with it a chemical library that millions of years of evolution produced through competitive pressures we will never fully reconstruct in a laboratory. We do not know what medicines will never be discovered because the species that contained their precursor compounds was driven to extinction before we looked. We never will know — which is precisely why the loss is so irreversible.

Reason 3: We Lose Clean Water — Wetlands Are the Planet’s Kidneys

Healthy ecosystems provide 75% of global freshwater resources, with wetlands playing a particularly critical role in water purification (WHO, 2025). Wetlands — marshes, swamps, bogs, river floodplains, mangroves — filter pollutants, absorb sediment, recharge groundwater aquifers, and moderate flood peaks. They are the planet’s kidneys: systems that process contaminated inputs and produce clean outputs.

Since 1970, 35% of global wetlands have been lost — drained for agriculture, filled for development, or degraded by pollution and altered water flows. The consequences are measurable: increasing waterborne diseases as water purification capacity declines, reduced freshwater availability for over 2 billion people, increased flood damage as buffering capacity disappears, and declining fisheries as breeding grounds are destroyed.

For India, wetland loss is a particularly acute crisis. India’s coastal mangroves — among the most biodiverse ecosystems on the planet — have been declining due to aquaculture conversion, coastal development, and pollution. The Sundarbans, the world’s largest mangrove forest shared between India and Bangladesh, faces simultaneous pressure from sea level rise, cyclone intensity increase, and freshwater flow reduction from upstream dams. The Sundarbans are not just a biodiversity asset — they are the primary protection for tens of millions of people against cyclone storm surges. Their degradation is simultaneously a biodiversity crisis and a human vulnerability crisis.

Reason 4: We Lose Climate Stability — Forests Are the Planet’s Lungs

Forests store 80% of terrestrial biodiversity and absorb approximately 2.6 billion tonnes of carbon dioxide annually (WHO, 2025). But the climate services of biodiversity go deeper than carbon sequestration. The Amazon rainforest generates its own rainfall through a process called the hydrological cycle: forest transpiration releases water vapour that forms clouds and falls as rain — not just locally but across thousands of kilometres, in a phenomenon scientists call ‘flying rivers.’ These atmospheric rivers carry moisture from the Amazon to agricultural regions across South America, providing rainfall to farms that produce food for hundreds of millions of people.

Deforestation disrupts this cycle. Destroy enough Amazon forest and the flying rivers weaken, regional rainfall declines, and agricultural regions that depend on that rainfall face drought — even if they are nowhere near the forest that was cut. This is ecological interdependence operating at continental scale: the fate of Brazilian farmers in São Paulo is linked to the fate of trees in the Amazon that they may never see.

India has its own version of this dynamic. The Western Ghats act as a moisture interceptor for the Indian monsoon — forests on windward slopes capture moisture from monsoon winds and release it gradually through the dry season, sustaining river flows and groundwater recharge across peninsular India. The degradation of Western Ghats forests does not just affect species living in the Ghats. It affects water availability for hundreds of millions of people in the lowlands who depend on rivers that the Ghats forests sustain.

Reason 5: We Lose Pandemic Protection — Biodiversity Is Our Immune System Against Emerging Diseases

75% of new and emerging infectious diseases in humans originate in animals — they are zoonotic diseases that cross the species barrier from wildlife reservoirs to humans (WHO). The relationship between biodiversity loss and pandemic risk is one of the most important and least publicly understood dimensions of the current biodiversity crisis.

Intact, biodiverse ecosystems contain pathogens within complex ecological networks. A diverse community of wildlife hosts means that each individual pathogen has many potential hosts — but most hosts are not particularly susceptible to any given pathogen, because the pathogen has not co-evolved specifically with them. This ‘dilution effect’ — identified by ecologists Felicia Keesing and Richard Ostfeld — reduces the concentration of competent hosts for any given pathogen and suppresses the transmission rates of zoonotic diseases.

When biodiversity is lost and habitats are fragmented, the species that survive best are often the generalist, disturbance-tolerant species — rats, bats, some rodents — that tend to be the most competent hosts for zoonotic pathogens. The natural diversity that diluted pathogen concentration is replaced by a community dominated by the species most likely to amplify it. Human settlements push into fragmented habitat, bringing people into direct contact with these high-competence reservoir species. The conditions for spillover — the jump of a pathogen from an animal reservoir to a human population — are created by the same processes that drive biodiversity loss.

SARS-CoV-2, Ebola, HIV, Nipah, MERS, and multiple avian and swine influenza strains all originated through human-wildlife interface disruptions — deforestation, bushmeat hunting, live animal markets, and the encroachment of human settlement into previously intact habitat. Each of these diseases produced massive economic disruption and human suffering. The COVID-19 pandemic alone cost the global economy an estimated $10–20 trillion. Biodiversity conservation — protecting the intact habitats that separate wildlife pathogen reservoirs from human populations — is one of the most cost-effective pandemic prevention investments available.

Reason 6: We Lose Soil Fertility and Agricultural Resilience — The Invisible Biodiversity Under Our Feet

Soil is not just dirt. A single teaspoon of healthy agricultural soil contains approximately one billion bacteria, hundreds of metres of fungal mycelium, thousands of nematodes, and diverse communities of protozoa, arthropods, and other organisms. This underground biodiversity drives nutrient cycling — converting dead organic matter into plant-available nutrients — soil structure formation, water infiltration, and natural pest suppression.

Industrial agriculture has been simplifying soil biodiversity for decades through intensive tillage, synthetic fertiliser application that bypasses microbial nutrient cycling, and broad-spectrum pesticide and herbicide use. The consequence is soils that increasingly depend on external chemical inputs to maintain fertility — soils that have lost the biological complexity that made them naturally productive. UN estimates suggest that at current rates of soil degradation, the world has approximately 60 years of farming left in its topsoil. This is not a geological timeframe. It is within the lifetimes of children alive today.

The mycorrhizal networks that connect plant roots — sometimes called the ‘wood wide web’ — are perhaps the most extraordinary example of functional biodiversity in soils. These fungal networks allow trees to share nutrients and chemical signals with each other, with older trees supporting younger ones, and with stressed trees receiving resources from healthy ones. Forest biodiversity, including the biodiversity of the soil beneath it, is a collective intelligence system — and one that agricultural monocultures are progressively dismantling.

Reason 7: We Lose Ourselves — The Psychological and Spiritual Dimension of Biodiversity Loss

There is a dimension of biodiversity loss that economic valuation cannot capture and that the species extinction statistics do not measure: the psychological, cultural, and spiritual impoverishment that comes from living in a world progressively emptied of its living community.

The biophilia hypothesis — proposed by evolutionary biologist E.O. Wilson in 1984 — suggests that humans have an innate emotional affiliation with other living organisms, evolved over millions of years of co-existence with diverse life. This is not sentimentalism. It is a hypothesis grounded in evolutionary theory and supported by a growing body of research showing that contact with natural biodiversity — hearing birdsong, seeing diverse vegetation, experiencing living ecosystems — measurably reduces stress hormones, lowers blood pressure, improves immune function, and enhances psychological wellbeing.

The forest bathing research — Shinrin-Yoku — documents the physiological benefits of time in biodiverse natural environments. The attention restoration theory of Kaplan and Kaplan shows that natural environments with high biodiversity restore directed attention capacity depleted by urban environments. The measurable health benefits of biodiversity contact are not incidental — they reflect the deep co-evolutionary relationship between human physiology and the living world.

When biodiversity is lost, these restorative environments disappear. Children growing up in urban environments with limited access to living nature develop what Richard Louv called ‘nature deficit disorder’ — not a clinical diagnosis but a description of the attentional, emotional, and developmental consequences of growing up without adequate contact with the non-human living world. As urban expansion, habitat loss, and agricultural intensification continue, these consequences become the default experience of increasing proportions of humanity.

India is one of only 17 megadiverse countries on the planet — a designation given to countries that together contain more than 70% of the world’s species while covering less than 10% of its surface. India contains four of the world’s 36 officially designated biodiversity hotspots — regions identified by high endemism (species found nowhere else on Earth) combined with high habitat loss.

The Western Ghats — a UNESCO World Heritage Site running 1,600 km along India’s western coast from Gujarat to Tamil Nadu — contains extraordinary endemism: 7,402 plant species with 24 endemic genera, 114 of 131 amphibian species endemic to the range, 107 of 227 reptile species endemic, and 16 of 137 mammal species endemic. The Ghats are older than the Himalayas and contain relict species tracing back to the Gondwana supercontinent. They are, in evolutionary terms, one of the oldest continuous biodiversity archives on the planet. Over 70% habitat loss has already been recorded.

The Eastern Himalayas represent the largest biodiversity hotspot in terms of area, with 10,000 plant species (3,160 endemic), 980 bird species, 300 mammal species, and remarkable amphibian diversity. The Himalayan hotspot is warming significantly faster than the global average — a pattern that is pushing species upslope until there is no more slope to occupy, at which point highland endemic species face local extinction with nowhere to go.

India’s biodiversity is not just an ecological asset. It is a civilisational heritage. The Vedic and Ayurvedic traditions are built on intimate knowledge of plant and animal communities — thousands of years of systematic observation of the relationships between living organisms and human health. The loss of biodiversity is therefore simultaneously the loss of the natural library from which much of Indian traditional knowledge was compiled.

The phrase Vasudhaiva Kutumbakam — from the Maha Upanishad — translates as ‘the world is one family.’ In the context of biodiversity, it is not a poetic aspiration but an ecological statement: all life on this planet is one interconnected family of beings, related through shared evolutionary history, mutual dependence, and the web of relationships that sustains the whole.

The Vedic cosmological framework of the Panchamahabhuta — the five great elements: Prithvi (earth), Jal (water), Agni (fire), Vayu (air), and Akasha (space) — is a systems description of the natural world in which each element is dependent on the others and on the living communities that mediate between them. This is not merely symbolic. It is a recognition that the health of soil (Prithvi), water (Jal), climate regulation (Agni), atmospheric composition (Vayu), and the living relationships between organisms (Akasha as the space within which life occurs) are interconnected dimensions of a single system — exactly what modern ecology calls the biosphere.

The Atharva Veda — one of the four Vedas — contains the Prithvi Sukta, the Earth Hymn, which begins: ‘Mata bhumih putro aham prithivyah’ — The Earth is my mother; I am the son of the Earth. This declaration of kinship with the living planet is not metaphor. It is the philosophical foundation of a relationship with nature characterised by reciprocity, reverence, and restraint — the opposite of the extractive relationship that the current biodiversity crisis represents.

The concept of Ahimsa — non-harm — as extended to all living beings in Jain philosophy and the broader Dharmic tradition is perhaps the most directly ecological principle in Indian thought. An ethics of non-harm toward other species is precisely the ethics that biodiversity conservation requires. The ancient Indian forest dwellers — the Vanaprasthas, those who withdrew to the forest in later life — lived in relationship with the forest rather than in exploitation of it. Sacred groves — Devaravanas or Orans — are found across India: patches of forest protected by local communities for generations precisely because of the cultural and spiritual significance of the living world. These sacred groves represent a long-running, community-based biodiversity conservation practice that predates the modern conservation movement by millennia.

The Kunming-Montreal Global Biodiversity Framework (2022) — the international agreement setting a target of protecting 30% of land and sea by 2030 — is, in a sense, a belated attempt to institutionalise what the Dharmic tradition encoded culturally: that there are parts of the natural world that should be protected from human extraction. The political negotiation required to reach 30×30 in international treaty form is a measure of how far modern governance has moved from the ecological wisdom that the Indian tradition preserved.

I want to say something about what biodiversity loss feels like — not just what it measures — because I think the measurement, however important, misses the dimension that matters most for how people actually relate to this crisis.

I grew up on the quiet banks of a river in Odisha where the day began not with the rush of the world but with birdsong, the sound of water, and the particular quality of morning light through living vegetation. That early formation created something that I can only describe as a felt sense of belonging to the living world — not as an observer but as a participant, one thread in a web whose other threads were the birds, the river, the trees, the insects, the fish, and the soil beneath my feet.

The 73% decline in wildlife populations is, in that felt sense, a 73% thinning of the world. Not just a reduction in some abstract metric of natural capital. An actual impoverishment of the living fabric within which human experience occurs. A world with 73% fewer wildlife populations is not just less biodiverse. It is less alive — and in that reduction of aliveness, something essential to human experience is also being reduced.

The Vedic concept of Rta — the natural order, the cosmic rhythm that sustains all life — describes what we are disrupting when we drive biodiversity loss at this pace. Rta is not just a philosophical concept. It is the actual functioning of ecological systems: the cycles of birth and death, predation and reproduction, decomposition and regeneration, rainfall and drought, that produce the conditions for life. Disturbing Rta produces consequences that extend far beyond the immediate disturbance — as the butterfly effect of ecology: the loss of a pollinator affects the food supply; the loss of a predator affects the vegetation; the loss of a forest affects the rainfall; the loss of rainfall affects the civilisation that depended on it.

The Arthashastra’s concept of Dharmic governance includes explicit prescriptions for forest conservation, protection of wildlife, and management of natural resources for sustainable yield rather than extraction. These are not incidental provisions — they reflect a systems understanding that the prosperity of a kingdom (what we would now call the economy) depends on the health of its natural foundation. This is what modern economics calls ‘natural capital’ — and what the $10 trillion annual cost of biodiversity loss confirms: the natural world is not a free gift but a foundation whose depreciation has costs that eventually come due.

We are, in the most literal sense, consuming our biological inheritance. The question is not whether the bill will come. It is whether we will choose to pay it preventatively — by protecting and restoring biodiversity now, at manageable cost — or reactively, after tipping points have been crossed, at costs that may not be manageable at all.

Wildlife populations down 73% in fifty years. Freshwater species down 85%. One million species threatened with extinction. $10 trillion in annual economic losses from biodiversity degradation. 75% of food crops dependent on pollinators that are declining. 50% of medicines derived from natural sources. 75% of new human diseases originating in animals. These numbers, taken together, describe not a peripheral environmental problem but a structural crisis in the foundations of human civilisation.

The Vedic wisdom — Vasudhaiva Kutumbakam, the world is one family; Mata bhumih putro aham prithivyah, the Earth is my mother — is not mythology. It is ecology expressed in the language of relationship rather than the language of metrics. The relationship it describes is real, biological, and in crisis.

Losing wildlife is losing ourselves — not metaphorically but literally: losing the pollinators that feed us, the forests that water and climate us, the ecosystems that protect us from pandemic, the soils that sustain agriculture, the plants that heal us, and the living world that makes us psychologically whole. The web of life holds everything. We are in it, not above it. And what we are currently doing to it will, if uncorrected, take us down with it.

The good news — and there is good news — is that biodiversity can recover when given the chance. Ecosystems are resilient within their tipping point thresholds. Species populations can rebound with protection. Wetlands can be restored. Forests can be replanted and allowed to regenerate. The IPBES 2024 findings are explicit: immediate action could generate $10 trillion in economic opportunity and support 395 million jobs by 2030. The cost of acting now is far lower than the cost of waiting.

The question is whether the next five years — which the WWF Living Planet Report identifies as critical — will be the years in which humanity chose to act, or the years in which it chose to continue on the current trajectory until the tipping points made the choice irreversible.
