NASA reveals incredible 'breathing Earth' animation

NASA has revealed stunning visualizations of our'breathing' planet, showing how vegetation has changed over the course of 20 years. Through ongoing satellite observations of Earth's surface, scientists have spotted long-term changes that could have major impacts on the different habitats and ecosystems across the globe. The maps also show drastic seasonal changes that take place on both land and water, as plant life blossoms and dies down over the course of each year. The visualization shows 20 years of observations, dating back to 1997. Vegetation on land is shown on a scale of brown (low) to dark green (high).
