They Cleared The Amazon. The Amazon Grew Back...

The Amazon is growing back… and the beef industry is accidentally responsible.

Cattle ranching accounts for roughly 80% of all deforestation in the Amazon. The pattern is consistent across decades: ranchers clear forest, burn the debris, plant non-native grasses, and run cattle on the new pasture. For a few years, sometimes ten, the land is productive. Then the soil begins to collapse.

Amazon soils are some of the most nutrient-poor soils on Earth. The forest that grows on them isn’t sustained by the soil, it creates its own nutrient system through decomposition, layering, and root networks built over centuries. When that forest is cleared and replaced with a monoculture of introduced grass, the nutrient cycle breaks. The soil compacts under the weight of cattle hooves. Erosion accelerates. The grasses that replaced the forest stop producing enough forage to make cattle ranching viable. Estimated to affect 50% of all Amazon pastures, this degradation cycle is not an accident or an exception. It’s the predictable outcome of the system.

When the land stops producing, ranchers leave. They don’t restore it. They move to the next patch of forest, clear it, and repeat the process. Behind them, on the degraded pasture they abandoned, something begins.
