Felix Finkbeiner, a student in Bavaria, challenged his classmates-and ultimately, children throughout the world-to plant a million trees in each country, an idea that grew into an international youth organization called "Plant-for-the-Planet." In 2011, the UNEP turned its Billion Tree Campaign over to the organization Felix had started. By that time, the UN program had celebrated the planting of 12 billion trees. But how much does it increase the world's tree population? [Source: Global Climate Change - NASA]
