Forests cover on Earth 9% more than thought: Survey
A global satellite survey has found hidden forests in poorly studied 'drylands', increasing the worldwide forest coverage by 9% from earlier estimates. Researchers searched over 2 lakh ultra-high-resolution Google Earth images, where each pixel corresponds to less than a metre on ground. They found the drylands to host 40% more forests than previously known, increasing the total tally by 9%.
