Plant een miljard bomen

"A campaign to plant a billion trees in a single year was launched at the United Nations Climate Change Conference in Nairobi, Kenya, in November 2006. The Plant for the Planet: Billion Tree Campaign is intended to encourage people and organizations everywhere to take small but practical steps to reduce global warming, which many experts believe is the most important environmental challenge of the 21st century."

"The campaign encourages people and organizations around the world to enter pledges on a web site hosted by the UNEP. The campaign is open to everyone—concerned citizens, schools, community groups, nonprofit organizations, farmers, businesses, and local and national governments. A pledge can be anything from a single tree to 10 million trees"
