5d. Control and eradicate non-native or genetically modified organisms harmful to native species and the environment, and prevent introduction of such harmful organisms.

This is an open field trial and there is a big risk of contamination with couch grass. It is only 50 metres from the oldest grass meadow in the UK and is the same distance from a conventional wheat crop.

As a farmer I am concerned that no-one knows the impact of GM on our health or the environment. I believe planting GM crops on a commercial scale is not a risk we should be taking.

No-one knows the impact of GM on our health or the environment

Gerald Miles rears livestock and grows organic crops on 120 acres of coastal land in Pembrokeshire. In 2003 he drove his tractor all the way from West Wales to Downing Street to protest about GM crops and to raise support from fellow farmers, after trial plots were planted near his farm.

In May 2012 he joined a group of activists at a protest near Luton aimed at destroying a trial crop of genetically-modified wheat. Gerald did not deny that research should be conducted into the genetic modification of crops, but he believes strict controls should be put in place first.

Gerald recently launched Wales’ first community supported agriculture scheme (CSA), where members or ‘sharers’ grow and share delicious organic food, in partnership with local farmers.

5. Protect and restore the integrity of Earth's ecological systems, with special concern for biological diversity and the natural processes that sustain life.
