NASA recently announced a major initiative to monitor the health of forests around the world. By 2023, NASA plans to deploy a new satellite system to observe the worldwide forests, giving us unprecedented insight into how our forests are changing. The satellite system will measure a variety of factors such as tree density, leaf area, and canopy height, giving scientists the data they need to assess the health of forests and how they are responding to climate change, deforestation, and other human activities. This data will be invaluable to help us protect our forests and mitigate the impacts of climate change.
