THREE years ago I wrote to HAS arguing against the use of wood as a bio-fuel.

I mentioned the essential part trees played in our environment.

Sadly, the industry has continued to use wood-chip, old timber and fast-growing timber.

I’m alarmed that the present Government proposes to sell off forestry land to private developers who are only in business to make a profit.

There’s an old saying that history repeats itself.

Our woodlands were only saved in the 19th Century thanks to coal. Let’s not tread the same path again.
