Global Project To Plant 5.5 Billion Trees

"The tree-planting campaign, if successful, will create the equivalent of another major tropical forest while improving the livelihood of as many as 80 million people, according to the International Center for Research in Agroforestry (ICRAF), which is spearheading the project... Planting trees on farms reduces erosion, improves plant nutrition for food crops, and replenishes the fertility of poor soil, says ICRAF. Trees also provide critical shade in the tropics and help regulate the microclimate of farms."
