Trees and global warming
Dear EarthTalk: Is it true that cutting and burning trees adds more global warming pollution to the atmosphere than all the cars and trucks in the world combined?

By most accounts, deforestation in tropical rainforests adds more carbon dioxide to the atmosphere than the sum total of cars and trucks on the world’s roads. According to the World Carfree Network (WCN), cars and trucks account for about 14 percent of global carbon emissions, while most analysts attribute upwards of 15 percent to deforestation.
