The hapless Australasian Antarctic Expedition is finally homeward bound - and thousands of trees will have to be planted to offset the carbon footprint.....
The expedition had pledged to plant about 800 kauri trees in Northland to cover its carbon footprint. Environmentalists believe planting trees helps to offset the impact of burning fuels such as diesel.

But former Act Party leader and Herald on Sunday columnist Rodney Hide said that would have to increase to about 5000 trees to make up for the fossil fuels burned in the rescue.

Expedition leader Chris Turney said more trees would be needed than earlier estimated but he was yet to work out how many.
