How the World's Forests Are Being Lost — And Why Our Counter Says 'est.'

There is a kind of loss that happens quietly, far from any city, under a canopy that hides it from view — and yet it is one of the most consequential things occurring on the planet right now: the steady disappearance of the world's tropical rainforests. It rarely leads the news on any given day. But measured across a year, it is staggering. This counter shows that loss as a running daily total. Like the population and carbon counters beside it, it wears an est. badge, and understanding why is the key to reading it honestly.

The number, and how to feel it

In 2024 the tropics lost roughly 6.7 million hectares of primary rainforest — the highest annual figure since record-keeping began, and an area nearly the size of Panama. That is a number almost impossible to picture, so the people who measure it translate it into something you can: about 18 football pitches every minute. Pitch after pitch of irreplaceable old-growth forest, all day, every day, all year.

Spread evenly across the year, that comes to roughly a fifth of a hectare every second — which is the rate our counter ticks at. By the end of a single day it has accumulated to around 18,000 hectares, a small national park's worth, lost in twenty-four hours.

That two ways of stating the same thing agree is also how we know the number is sound. Take the football-pitches rate the scientists quote and convert it back — eighteen pitches a minute, a pitch being about seven-tenths of a hectare — and you land on the same fifth-of-a-hectare-per-second figure that the annual total divided by the seconds in a year produces. The arithmetic checks against itself.

Nobody watches every tree fall

Here is what the smoothly climbing digits are designed to let you forget: there is no live feed of global deforestation. No system reports, second by second, every tree cleared or burned across the Amazon, the Congo Basin and Southeast Asia. The loss happens in thousands of places at once, much of it remote, much of it under cloud, much of it deliberately hidden.

What exists instead is patient satellite accounting. The Global Land Analysis and Discovery lab at the University of Maryland processes Landsat satellite imagery across the entire planet — more than a million images over the full record — at about thirty-metre resolution, detecting where tree cover vanishes from one year to the next. The results are published free each year on the World Resources Institute's Global Forest Watch platform. It is meticulous, world-leading work. It is also, unavoidably, an annual measurement assembled after the fact, not a live alarm.

Why we count the rainforest, not every tree

The same satellites measure something broader too: gross tree-cover loss across the whole planet, which came to about 30 million hectares in 2024. It would make for a bigger headline number. We deliberately do not use it.

That broader figure folds in things that are not permanent deforestation — timber plantations being harvested and replanted, tree crops on a rotation cycle, fire damage in boreal forests that will regrow. Tropical primary forest is different: old-growth rainforest that has never been cleared, the richest store of carbon and life on land, and the kind of forest that does not come back on any human timescale. When people picture "the rainforest being lost," this is the number they mean. Choosing it over the larger one is the honest call, even though it makes the counter tick more slowly.

So what is the counter doing?

It is taking the most recent verified annual figure — the 2024 tropical primary forest loss — and spreading it evenly across the seconds of the year, then showing how much has accumulated since midnight UTC. Nothing more, and nothing it pretends to be.

Real loss is not even. It follows the dry seasons, surges in a drought year when fires run wild, and eases when the rains return — 2024 was so bad precisely because the hottest year on record met widespread drought, and for the first time fire overtook farming as the leading cause. A genuinely live world figure would lurch and pause with all of that. Ours doesn't, on purpose: it ticks at the steady yearly average so it conveys the scale and pace honestly without implying a precision nobody has. The honest read is the leading figures and the rate — eighteen pitches a minute — not the last digits rolling past.

Where to see it

The counter is the single planetary figure. The story behind it lives across the maps. The wildfires layer on the Earth canvas shows the live fire detections that drove so much of the 2024 loss; the forest-cover map in Atlas shows how forested each country is to begin with, and which nations still hold the great forests worth protecting. Tap through and the abstract number becomes a place — a burning frontier in the Amazon, a shrinking green in the Congo Basin, a planet's lungs counted from orbit.

It is a hard number. It is also, in being measured at all, a kind of hope: you cannot protect what you cannot see, and for the first time in history we can see the whole of it.
