Spindoc,
You ask about causes, I have mentioned the oil depletion may
times as a cause, and as you are familiar with that firm, have you
read /home/barry/Documents/Economy/TPSI_009_Perfect_Storm_009.pdf
it is has a number of causes more than I originally had known about.
It is hardly investment advice unless it says, run for the hills and buy five acres,

You misunderstand, you said;
they do not provide the answers, they are your job.
No it is not my job.
I cannot suggest real solutions because they are beyond my powers.
I can only hope that by ringing the bell that someone who has the
power and can see that there is a fire wakes up !
I can see that this is such a massive problem it will need someone
of national or indeed international status to undertake a diversion of
all national aims onto the problem.

When I see how difficult it has been to get unified international
action on climate change I don't see how it can be solved in time.
