Last year's Radio 4 'natural histories' series took us to the oak:
Futures Forum: The Oak @ Natural Histories on BBC Radio 4
At the same time, there was also a fine programme on BBC4 on the oak:
Futures Forum: The oak tree @ BBC4 ... and @ Sidmouth Science Festival
Within the context of climate change, it is clear that trees play a vital part:
Futures Forum: TEEB: The Economics of Ecosystems and Biodiversity
Indeed, they can help us 'engineer' our way out of too much carbon in the atmosphere:
Futures Forum: Climate change: and the false hope of the UN conference >>> "We must look at the full spectrum of geoengineering." But "the high political and environmental risks associated with this must be made clear so that it is never used as an alternative to making the carbon cuts that are urgently needed."
In the BBC4 documentary, "Dr Nick Lane from University College London, describes perhaps the most
important moment in the history of life. The moment when leaf cells gained tiny
structures called chloroplasts, which use sunlight to absorb carbon dioxide from
the atmosphere, create sugars for the plant to live on and release oxygen – the
gas all animals need to breathe."
