Seeing the forest and the trees, all 3 trillion of them
A recent study by researchers at Yale University revealed that there are more than 3 trillion trees now growing on the planet, seven times more than scientists previously thought. Using a combination of satellite imagery, forest inventories, and supercomputer technologies, the international team of researchers was able to map tree populations worldwide at the square-kilometer level. Their results, published in the journal Nature, provide the most comprehensive assessment of tree populations ever produced and offer new insights into a class of organism that helps shape most terrestrial biomes.
