According to Reuters, more than two billion trees have recently been planted around the world as part of the UN’s campaign to combat climate change. But there’s more. The worldwide tree planting campaign is aiming to reach a total of 7 billion by the end of 2009 – that means just over one for everyone on the planet.

The United Nations says the campaign has exceeded expectations since it began in late 2006 with a goal of planting one billion within a year: two billion have been planted already. That means another 5 billion by late 2009.
