A logger cuts down a beautiful forest because he is selfish and
inconsiderate and cares nothing for the habitat of animals or the preservation
of our woodlands. Your assignment: Discuss how the birds and squirrels might
feel as the logger cut down their homes just for a measly profit of £20.

6. Teaching Maths In 2009
A logger is arrested for trying to cut down a tree in case it may be
offensive to the Amish or other religious groups not consulted in the
felling licence.
He is also fined a £100 as his chainsaw is in breach of Health and
Safety legislation as it is deemed too dangerous and could cut
something.
He has used the chainsaw for over 20 years without incident; however,
he does not have the correct certificate of competence and is
therefore considered to be a recidivist and habitual criminal. His DNA
is sampled and his details circulated throughout all government
agencies. He protests and is taken to court and fined another £100
because he is such an easy target. When he is released he returns to
find Gypsies have cut down half his wood to build a camp on his land.
He tries to throw them off but is arrested, prosecuted for harassing
an ethnic minority, imprisoned and fined a further £100. While he is
in jail the Gypsies cut down the rest of his wood and sell it on the
black market for £100 cash. They also have a leaving BBQ of squirrel
and pheasant and depart leaving behind several tonnes of rubbish and
asbestos sheeting. The forester, on release, is warned that failure to
clear the fly-tipped rubbish immediately at his own cost is an
offence. He complains and is arrested for environmental pollution,
breach of the peace and invoiced £12,000 plus VAT for safe disposal
costs by a regulated government contractor.
Your assignment: How many times is the logger going to have to be
arrested and fined before he realises that he is never going to make
£20 profit by hard work, give up, sign on the dole and live off the
state for the rest of his life?

A logger doesn't sell a lorry load of timber because he can't get a
loan to buy a new lorry because his bank has spent all his and their
money on a derivative of securitised debt related to sub-prime
mortgages in Alabama and lost the lot with only some government money
left to pay a few million pound bonuses to their senior directors and
the traders who made the biggest losses.
The logger struggles to pay the £1,200 road tax on his old lorry;
however, as it was built in the 1970s it no longer meets the emissions
regulations and he is forced to scrap it.
Some Bulgarian loggers buy the lorry from the scrap merchant and put
it back on the road. They undercut everyone on price for haulage and
send their cash back home, while claiming unemployment for themselves
and their relatives. If questioned they speak no English and it is
easier to deport them at the government's expense. Following their
holiday back home they return to the UK with different names and fresh
girls and start again. The logger protests, is accused of being a
bigoted racist and as his name is on the side of his old lorry he is
forced to pay £1,500 registration fees as a gang master.
The Government borrows more money to pay more to the bankers as
bonuses are not cheap.
The parliamentarians feel they are missing out and claim the
difference on expenses and allowances.
You do the maths.
