    Posted By: Cliff PopeWhat happens to all the worms and micro organisms in the soil when you build an eco-house? Do you carefully re-home them somewhere in an appropriate environment
    That (and every other impact) may or may not be critical, or crucial, and compensatory measures may or may not be necessary - at present we have no idea.
    Posted By: SeretNot all changes made to the "natural" order of things are inherently bad. Natural systems can cope with fluctuation
    Posted By: fostertomhow do you know whether what you do is within the 'coping' limits of the natural order? Really, we don't, because we don't think in those terms


    Posted By: Cliff PopeSurely the biggest negative impact is by building the house in the first place
    The way even we greenies do it still - prob true. But need not be so.
    Posted By: fostertomWe don't even have it on our wish list, that what we do could actually assist the natural order in making good previous accumulated damage

    I'm with Cliff, - and I'm not denying that a GSHP will change things I just have bigger (or apparently bigger) things to fret over, and for all I know it might even change things for the better. Draining land, flooding it, harvesting, planting - all are going to change the land we live on.

    Was a bit on radio about a Polder that has to be reflooded because of EU environmental laws:

    Wow, a few new comments. Like Fostertom has already said it is surprising how much resistance there is to discuss the OP's question. I am of the opinion, based on my logic, that individual cases of GSHP (or house building) will not have any real influence but if done on a large urban scale it most definitely will have though we do not have an idea if it is positive or negative.

    Caught a bit of the Radio 4 Material World programme last night talking about the sustainability of extracting heat from the old mine workings under Glasgow. Unfortunately, going in and out of little valleys on the road, FM was very broken and LW was bleedin' cricket so I didn't get it all. Perhaps somebody could iPlayer it and report.

    GSHP sunk into old coal mines, they could do the same with flooded tin mines. Nothing technically new, just that they have made a map and are trialling it.

    Don't mess with old heavy-metal workings - super-toxic, Env Ag will rightly control it out of sight. My own beautiful verdant Teign Valley, for 100 Victorian/Edwardian years one big industrial scene, has many closely-watched no-go sites, waste heaps on which still nothing grows, all precariously kept from dumping their load into the river.
