俯瞰生态圈

Technology is transforming how we see and protect nature, uncovering details once invisible from the ground. With airborne lasers and spectrometers, scientists can map forests in 3D, revealing everything from carbon stocks to the secretive hunts of male lions. Vivid new data shows how much remains unknown, even as humans reshape ecosystems at a rapid pace. To save forests and biodiversity, deeper understanding is as vital as the tools we use.
