Treedom, if you've not yet come across it, is a social enterprise that allows you to plant a tree in a sustainable agroforestry project, gift it to your nearest or dearest, and follow its progress online. The world needs billions more trees to help combat climate change, so giving the gift of a tree to someone who desperately needs it is surely the best present of all. Prices range from a cacao at 14.90 euros to a baobab at 69.90 euros. Choose where the tree should go - Kenya, Cameroon, Tanzania, Nepal or Columbia.
