27 July will be National Tree Day in Australia.
Australia already has about 1.5 million square kilometres of forest and woodland, equal to an area about the size of Mongolia, or larger than the entire Northern Territory
National Tree Day is a ruse by the Toyota Corporation to seek to gain enough greenie points to get large government grants to make resource guzzling Priuses and to continue churning out SUVs. It's pretty similar to this initiative involving GM Holden planting trees in the Murray Darling Basin.
All of which makes this study kind of interesting reading.
