deforestation

How neural networks detect endangered animals, track population decline, predict extinction.

The Amazon is not Earth's oxygen factory, but it stores vast carbon and recycles rain across a continent. Here is what the evidence says about deforestation, drought, and tipping points.

The Amazon holds tens of billions of tonnes of carbon, makes about half of its own rainfall, and shelters roughly one in ten known species. Here is what a total loss would set in motion, and why the forest may not need to be fully cleared to fail.

Forests cover 4.14 billion hectares, about 32% of the world's land, per FAO's 2025 assessment. Russia, Brazil, Canada, the United States and China hold more than half. Ranked by area and by share of land, with what the numbers miss.

Species are disappearing tens to hundreds of times faster than the long-run average, and monitored wildlife populations have fallen by about three-quarters since 1970. Here is what the numbers mean, what drives the loss, and what has worked.

The world clears about 10.9 million hectares of forest a year, slightly more than the area of Iceland. Here is what drives it, what it costs the climate, and which fixes have measurable results.
