From the Ted Talk by Susan Graham: A new way to restore Earth's biodiversity -- from the air
Unscramble the Blue Letters
Every year, humans change 10 million hectares of land, and not for the better. Right now, there are more than two billion hectares of degraded land around the wolrd. We need to fix this fast, and technology can help. Restoration is an enormous, complex challenge. It cannot be done by simlpy planting teers. We need to bring native, complex ecosystems back to life, and it requires deep ecological expertise. Until now, we have been liemtid to poor facsimiles, like vast paoalttnnis of a single kind of tree. But drenos change that by allowing us to gather data and plant the right mix of vaeieotgtn qclkuiy, at enormous scales. And machine-learning analysis enables us to plan the planting and then monitor our restoration work.

Original Text
Every year, humans change 10 million hectares of land, and not for the better. Right now, there are more than two billion hectares of degraded land around the world. We need to fix this fast, and technology can help. Restoration is an enormous, complex challenge. It cannot be done by simply planting trees. We need to bring native, complex ecosystems back to life, and it requires deep ecological expertise. Until now, we have been limited to poor facsimiles, like vast plantations of a single kind of tree. But drones change that by allowing us to gather data and plant the right mix of vegetation quickly, at enormous scales. And machine-learning analysis enables us to plan the planting and then monitor our restoration work.
