I NOTE your report on demands for the SNP leadership to detail what it covered by its moratorium on fracking.

Each political party have stated their opinions on fracking.

The Conservatives stated: "Successfully extracting shale gas can create a whole new British industry."

The Labour Party said: "It does make sense to investigate fracking, with a robust regulatory framework."

Ukip stated they “support the development of shale gas with proper safeguards".

The Green Party: "A ban on all UK fracking operations and a withdrawal of licences as soon as possible."

The SNP's view was "every SNP MP has voted in favour of a UK-wide moratorium."

Now the meaning of the word “moratorium” is “a legally authorised ban or delay”.

This allows the SNP to examine and investigate the pros and cons of fracking, which is similar to what the Labour Party stated.

So here are some facts to ponder as regards fracking. Chemicals used in fracking are toxic; waste water from fracking cannot be recycled, therefore somewhere must be found to store it, a bit like spent nuclear fuel rods; one well can in its life time use as much as five million gallons of water. Exploratory drilling, and fracking has caused earthquakes and tremors.

We have the geological fault line that runs through the Great Glen; what effect could fracking have on that?

Fracking has been banned or suspended in Germany, Bulgaria, Romania and Texas.

I am sure the First Minster and her Cabinet are looking at these issues, and will come to a measured and informative decision.

But do we really need fracking at all when wind energy is now producing 50 per cent of our electricity, and there is no harmful by-product to be disposed of or stored?
