Our Food, Our Planet
The food system is the single largest driver of environmental degradation on Earth. It is not adequately addressed in the Global Biodiversity Framework. It is not mentioned in the Paris Agreement.
Systems bend. Then break.
Most environmental damage feels gradual. But ecosystems under sustained pressure don't decline in a straight line. They absorb stress until they can't, and then they shift state, often abruptly, often irreversibly.
The shape of collapse

The journey from A to E can take decades. The journey from C to E can take years.
The largest source of ecosystem pressure on Earth is our food system.
One system. One failure.
40% of all habitable land on Earth is consumed by the food system. Look at what that land actually does. And for whom.[2,3]
SHARE OF ALL HABITABLE LAND
82%
of all agricultural land on Earth feeds livestock; not people directly[2]
One machine. Many wounds.
These are not separate crises. They are the same industrial food system exerting pressure on every system that sustains life.[4-10]
To maximise output from the fewest crops, governments pay $635 billion per year in subsidies to industrial monoculture[10]. Non-subsidized varieties become economically unviable and disappear. Farmers push into forest frontiers to grow what the subsidies reward. The money makes the machine self-perpetuating. And as subsidies concentrate production, a second collapse begins: not of land, but of life itself.
A century of Vanishing crops.
100 years ago, farmers cultivated thousands of crop varieties. Today, almost all of them are gone; replaced by a handful of globally profitable commodity crops. Many of them made profitable by industrial subsidies.[11]
CROPS: THEN AND NOW
Surviving (~10%)Gone from farms (~90%)
Today: only ~10% of formerly cultivated varieties survive on farms. The rest exist, if at all, only in seed banks.[11]
The 10 crops that ate the world
Barley, cassava, maize, oil palm, rapeseed, rice, sorghum, soybean, sugar cane and wheat account for 83% of all harvested food calories on Earth.[12]
SHARE OF GLOBAL HARVESTED FOOD CALORIES
All other crop varieties combined, thousands of species, produce only 17% of global calories. And declining.
Starving. Stuffed. Simultaneously.
Cheap, subsidized commodity crops flood the food supply with fats and sugars. The result is hunger and obesity. Not as opposites, but as twin products of the same machine.[13,14]
ONE TABLE · TWO OUTCOMES
30–40%
of all food produced is never eaten.[15]
9M
tonnes of marine life are discarded as bycatch annually.[16]
The waste is structural, not incidental.
The machine funds itself.
The food system is not underfunded: it is misfunded.
THE FLOW OF MONEY
23×
more flows toward harming the food system than reaches it for positive transformation
Harmful subsidies already exceed even the upper-end transition need. Only 4% of global climate finance reaches the food system, despite it driving a third of emissions.[17] The problem is not scarcity. It is direction. More than enough money exists to transform the problem. But it is spent to make the problem worse.
14%
of annual forest loss is driven by subsidies for soy, palm oil and beef.[10]
The solution, Four shifts.
The diagnosis is established. The solutions exist. None require new technology. All require political will and redirected money.
Shift 1
Nature-positive production
Work with the land, not against it.
In Andhra Pradesh, India, 630,000 farmers transitioned to community-managed natural farming. Crop diversity doubled. Prime crop yields rose 11%. Net income rose 49%. Not a single hectare was added.[18,23]
The yield gap is large enough in many regions to meet demand without touching another forest. The obstacle is not agronomic. It is financial.[10]

7.42
Earths needed if all ate like the highest consumers
Shift 2
Healthy diets within planetary limits
What the world eats determines what the world needs.
If all countries adopted the diets of the world's highest-consuming economies by 2050, food emissions would exceed the 1.5°C target by 263% and require up to 7.42 Earths. The lowest-consuming economies require under one.[19,20]
The path forward is not uniform. Countries facing hunger need more food. High-consumption economies need less meat and different choices. The direction depends entirely on where you start.
Shift 3
Cut food loss and waste
The food already exists. Stop losing it.
30–40% of all food produced is never eaten.[15] In Lake Naivasha, Kenya, 146 farmers collectively built solar-powered cold storage. Post-harvest loss fell from nearly 50% to under 10%.[21] No policy change. No new variety. Just infrastructure and coordination.
9 million tonnes of marine life are discarded as bycatch each year.[16] A structural outcome of how fishing is optimised, not an accident.

more flows to harm than reaches food systems for good
Shift 4
Redirect finance and reform governance
The money exists. It is flowing the wrong way.
$635bn in agricultural subsidies and $22.2bn in fisheries subsidies flow annually toward the practices driving this crisis.[10,24] Together they exceed the $200–500bn needed to transform the entire food system.[22]
The ask is not new money. Every dollar subsidising deforestation-linked soy, palm oil, and beef could be building cold storage in Kenya or supporting smallholder transitions in Andhra Pradesh.
Food systems sit outside the Paris Agreement and the Global Biodiversity Framework. That is not an oversight. It is a choice that can be unmade.
Working with the environment rather than against it would cost less, feed more people, sustain more species, and produce more diverse, nutritious food.
The obstacles are not technical. The solutions exist. The money exists. It is currently misdirected. The land is the same. The machine is the same. The choices shape our future.
