Lets see if we can make it simpler: Situation a) carbon goes into plant, carbon is stored 'n' years (sequestered) within tree, tree is harvested (new tree is planted and starts capturing/ sequestering), same amount of carbon released when burnt = carbon neutral. Situation b) carbon goes into plants, plants are buried in large volumes + heat pressure + time (millions of years), forms fossil fuels, man releases carbon from them not at the same rate as sequestered, but within 200 years or so = current problem and most definitely not carbon neutral.
I assume you mean the Y2K problem. Contrary to the urban myth that it was a myth and a beat-up the way the potential (ie: possible) negative consequences of the Y@K issue was dealt with is a good example of what can be done when a problem is recognised then worked on over a number of years by many people - ie: few if any negative consequences.
Fearful people and armegeddonists will always find reason to run and hide when their ignorance drives their emotions into action, but although there were media stories of potential negatives that were gross exaggerations, mostly what happened was that computer software all over the world was altered over more than ten years to make sure that there were no consequences of significance. And it worked! Laypeople who did not understand the issue might have been annoyed because 'nothing happened', but that was the intended and positive result.
No doubt some people and companies were told porkies and were ripped off, no doubt some carpetbaggers made a killing, but the problem was really those who were industry knew what needed to be done, action was taken to get it done - and it worked. There was no grand world-wide conspiracy on Y2K, but rather world-wide co-operative effort to identify a problem and fix it.
Just like climate change really - the issue is not so much who caused, but looking at the science that tells us what is happening, looking at the science that tells us what can be done to mitigate negative affects and acting on the evidence that points us in a sustainable direction. Warming or not there are facts we know:
a) the Earth is a finite closed-loop system - the original terrarium albeit a large one;
b) we have limited resources and all we do to our air, our soil and our water is recirculated whether we like it or not;
c) so unless we want to poison and ruin our air, water and soils (on which we all depend to survive) we have no choice but to eventually move to understand that closed-loop and to live appropriately to an organism inside a terrarium;
d) that means we move as fast as possible to cease doing what we know is not sustainable (whether than be oil running out in 50 or more years or coal running out in 300) and doing what we know is;
e) we are like the frog in the saucepan of cold water on the stove, if we are smart enough we will realise that we need to jump out before the water gets so hot we no longer can; and
f) it is actually economically smarter to do this sooner than later (unless you are one of the small group of very rich people who own fossil fuel companies).
This does not mean returning to some supposed 'golden age' of superior agrarian self-sustaining lifestyle, but rather a re-think of the way we have started to do things mostly in only the last 30 or 40 years. If we want to retain those changes then we need to do so in smarter ways, by better design, use of new technologies, placing a real cost on our energy uses, converting to a solar economy (wind, sun, ocean, geothermal - all are driven by the sun), placing a real value on what we currently account for as 'externalities' (eg: forests that we do not cut-down) and so on. Even simpler things too - like Billy Connolly's comment on Scotland's bad weather "No such things as bad weather - only wrong clothes!".

G'day Bloss,
Generally agree with what you say but in Scotland there are plenty of clothes to take off!! Not so sure here - not that I'm against nudity but the skin cancer may be a problem!!
To go back to Mega's original post and try and keep this thread on track - I believe we all need to look at how and why we want to use the resources we have available to us. To grow something so we might be able to harvest it only for firewood and/or a little woodturning is absurdly inane. Apologies to Mega for your post and reasoning but I firmly believe the tenets of your desires are seriously flawed.
There are soo many trees felled and chipped with no regard to their potential for anything!! It all gets chipped!!!!!!!!
Developers are afraid to let the timber off the site for green protest, so they chip it!! The beautifully grained forks are mulching your gardens, The usable lengths of timber, years old are chipped and spread on the local roundabout!! - the potential firewood - chipped. Then the developers BUY chemically treated timber for landscaping and public amenities.
Just get the feeling somewhere we have developed this disposable attitude to a point we may well dispose of the human race as we know it.
My point which I feel seems lost is that we seriously need to look at how we use this resource we collectively are so fond of. Have a look at the range of timber available in normal timber outlets and you will not find anything of quality - it's on your garden - meanwhile your door jambs and architraves are fabricated from sticks, finger jointed together.
OK - off the soap box now.

Not sure what posts you read, but Mega's initial question was what trees she might grow in a sustainable way to get timber for her needs. I think it was rude of you to suggest it is inane for an individual to wish to be able to enjoy her comfort with wood heating and enjoy woodworking too and to want to do so without negative environmental effects by growing more than enough on her own land. I replied first to suggest looking at what grew well locally then responded to some later posts on related, but often divergent subjects. Perhaps my responses to these is what has you all fired up - I suggest you read the whole thread as it seems you have not understood what I was saying.
I am sure Mega can answer for herself although seems to have been sensible enough (unlike me) not to engage in the argy bargy, but it is clear to me that she fully understands the need to preserve & protect resources and was seeking advice on how she might do that on a local scale. Neither her or I could remotely be thought to be advocates of the sort of wasteful approach to wood and timber that your post raised (with sometimes exaggeration - eg: "it all gets chipped!!!!!", well no it doesn't, but I agree too much does and with little or no thought of consequences or sustainability).
So as is often the case on these matters we seem to be in furious agreement.
