In January 2007, when Finkbeiner was nine years old and in fourth grade, inspired by hearing of Nobel laureate Wangari Maathai, he gave a class presentation on global warming in which he suggested to classmates that children should plant one million trees in each country of the world. Together with many of his classmates, Felix planted a tree on 28 March 2007 and launched Plant-for-the-Planet. After three years, the initiative planted its millionth tree. At age 10 he spoke in the European Parliament and at age 13 at the UN General Assembly. A decade later, he leads an organisation with 130 employees internationally and 70,000 members in 67 countries.Plant-for-the-Planet has hosted over 1,200 Academies during which participants between 10 and 14 learn about global warming and the importance of trees, practice public speaking and make plans on how they want to contribute to tackling global warming. The organisation currently restores 22,500 hectares of forest on the Yucatán Peninsula in Mexico by planting on average one tree every 15 seconds. Furthermore, Plant-for-the-Planet leads the UN Billion Tree Campaign, as part of which 14 billion trees have been planted so far by contributing companies, organisations and governments. Plant-for-the-Planet's The Change Chocolate ("Die Gute Schokolade") is sold in 20,000 stores throughout Germany and Austria. The chocolate is Fair Trade and carbon neutral. The profits are used to fund the tree-planting efforts in Yucatán. Thus, with every five bars sold, one tree is planted.
