This is what you have been writing to us about this week.

I am afraid Keith Chamberlain is incorrect in saying “in respect to water, chalk and trees do not have any credence as we have adequate efficiency of these natural resources” (BFP letter, ‘We need a modern transport system like HS2’).

The United Kingdom has one of the lowest percentages of tree cover, compared to that in a substantial number of European Countries, that is why there is currently a huge nationwide attempt to remediate this. Water shortages are predicted to be a problem in most of Southern England and possible loss of aquifers in the chalk due to HS2 tunnelling has the potential to aggravate this.

The potential damage to the local chalk streams, the Misbourne and the Chess would be a disaster.

Chalk streams are unique in their flora and fauna, with their year round constant temperature and with 85% of the world`s chalk streams being in the United Kingdom, the loss of two would be devastating both locally and nationally.

The Chilterns are classified as an AONB and having seen the devastation locally caused by the construction of HS2 it is a tragedy.

The Covid crisis has illustrated how it is now possible, with modern communications, for many to work from home, so the need for rail travel is diminishing and with it the need to save a few minutes on the rail journey from and to London and Birmingham.

Whilst I agree that Brunel's achievements were and are a great legacy they also came at great cost.

I visited the Brunel Museum in Bristol and seem to recall the final cost of building the Great Western Railway were of the order of double the original estimate, so what is HS2 going to cost us and who is going to pay?
