I've not been watching much else on TV lately apart from the excellent Mark Steel Lectures and the awesome Planet Earth.
It's Not Easy Being Green on BBC2 is an interesting view of someone trying to establish a more sustainable lifestyle, but so far most of what they are doing is not very applicable to the average household. How many of us have a handy stream to run a waterwheel? We try to do our bit by recycling and reducing energy usage, but things like having to have two cars to get us to work are not so good.
