The voyage and rescue emitted lots of carbon dioxide through the burning of fossil fuel — which climate scientists on the expedition believe is the main driver of global warming — so the expedition has promised to plant about 800 kauri trees in New Zealand to offset its contribution to global warming, reports APNZ.
Environmentalists argue that planting trees can offset carbon emissions from burning fossil fuels.
The expedition’s promise to plant 800 trees may be too few. Rodney Hide, the former head of New Zealand’s ACT Party who now writes for the Herald on Sunday says that the expedition would have to plant about 5,000 trees to offset the fossil fuels burned during the rescue of the failed expedition.
