A Cultivated Planet

Each pixel on the map highlights the areas covered by croplands and pastures across the world. Humans have converted ~12% of the earth’s ice free land surface area to grow crops, fuel, and fibre, and ~22% for grazing cattle, pigs, goats, sheep, chickens, and other forms of livestock. Agriculture represents the largest human land footprint on the planet. Rising demand for agricultural products is currently straining the Earth’s life supporting systems.
