Planting a tree against global warming is a complicated process. And most of the world can't do it as they lack the land and resources.
Idea: The World Wide Wood
Combatting global warming has never been easier. Plant a tree online in the "never ending forest" – and it will be planted in real life by the children's charity Plant for the Planet.
Children in schools around Germany designed and created trees that were plantable simply by drag and drop.
The online landscape used multiple look techniques, and sews them together in a seamless design patchwork.
