我們的森林究竟由什麼組成的？生態學家 葛瑞格.阿斯納 (Greg Asner) 從空中，利用光譜儀跟高功率雷射繪製自然地圖，以細膩的3D圖像展現大自然的千變萬化。 這是他稱為「高科技會計系統」的技術。 這段精彩的演講，阿斯納提出明確的訊息：我們需要多的資訊，找出新的方法，來拯救我們的生態系統。 



空中所見的生態環境

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.
