The United Nations Environment Programme (UNEP) launched a program based on the slogan "Plant for the Planet: the billion tree campaign”. The purpose of this initiative is to encourage people from every country, community, organisation and government to commit to planting a certain number of trees and registering its contributions via the campaign website. The goal was to have at least one billion trees planted throughout the world in 2007.
The campaign encourages the planting of indigenous or acclimatized trees in a local environment. The site provides advice and hints for planting a tree and guides you toward partner associations such as the World Agroforestry Centre (ICRAF) that are capable of offering helpful advice.
