    Part of the answer was shown in the BBC 2 film A Farm for the Future. If you missed it on Friday evening you can see it on i-player: http://www.bbc.co.uk/dna/mbpointsofview/F1951566?thread=6345097

    This really is an excellent programme and well worth watching. It was made by Rebecca Hoskins, famous for her plastic bag campaign.

    The link you actually need is

    http://www.bbc.co.uk/iplayer/episode/b00hs8zp/Natural_World_20082009_A_Farm_for_the_Future/

    I would disagree with Bif about it being "an excellent programme and well worth watching". It is, in fact a bloody excellent programme that should be compulsory viewing for everyone.

    The film doesn't preach, it simply states it as it is.

    Thank you for the link, Bif. We don't usually agree, but I'm with you on this.

    Oh yes, I put the wrong link. Sorry and thanks Joiner. That link takes you to the discussion on the Points of View message board.

    There's a piece about the film and lengthy discussion on The Oil Drum at http://europe.theoildrum.com/node/5120

    One of the permaculture places featured in the film is Tir Penrhos Isaf http://www.konsk.co.uk/index.htm . Click on 'Latest news and updates' for what Chris and Lyn Dixon have to say about the film.

    Martin Crawford of the Agroforestry Reseach Trust http://www.agroforestry.co.uk/ writes about the programme on the Dartington website http://www.dartington.org/sustainability/the-agroforestry-research-trust-to-feature-on-bbc2s-natural-world.

    with regard to loss of energy supplied by oil and unlimited solar energy
    did anybody watch this , and whats the thoughts on it as a solution to our energy requirements into the future
    with unlimited energy supply , would high population still be a problem ?

    You first need to make it available to everyone.

    Ralph, suggest you use ip proxy hosting/masking so that it appears your IP is situated in the UK (or the US if you want to watch movies on Hulu :)

    This is what I do to watch Iplayer stuff

    OK. Compulsory viewing for everyone in the UK.

    James - I saw that too... and broadly agreed with what the chap was saying..

    But we must still control the population.. more people, even with fusion, will still consume more than the planet has to offer.

    Possibly so, although with effectively unlimited energy resources we could recycle all materials and grow or manufacture enough food. The problem would be when the population rises to levels where the total retrievable physical resources of the planet are insufficient. Eg, not enough rare earth metals to go round for devices which need catalysts, even with 100% recycling. We might even be able to degrade the biosphere to near-desert conditions across large tracts of the world and still survive comfortably in huge numbers.

    Wouldnt all that unlimited energy/heat creation cause......... global warming?

    In the same way that the vast increase in energy use in the 20th century might help explain global temp increases

    Current human un-natural conversion of chemical to heat energy then dumped on the planet's surface is about one 17,000th of daily solar input - so probably not too significant so far.

    The effect of that human activity on the biosphere's temp is not because of the raw heat dumping, but because of its side-effect of increasing the emission of greenhouse gasses, which increases the equilibrium temp at which the solar-in/re-radiation-out balance stabilises.

    Unlimited population growth
    = NO room for wildlife
    Now how green is that?
