Images have a way of penetrating the mind and conveying information more immediately and powerfully than reams of words and, as far as images of our planet go, they don't come much more powerful than Google Earth.
The application - which has already done its fair share of enabling people to use technology for the good of the planet - has launched a new Outreach programme, encouraging us at Greenpeace and other organisations to use the application to spread global awareness.
And with 3.5 million users, that's potentially a fair bit of global awareness. The Greenpeace layer launched last week, with 20-odd datapoints showing how forest destruction around the world is contributing climate change. We're going to be adding to that over the next few months, with videos and pictures on all of our campaigns from offices around the world.
