Giggirl, of course farmers need to survive, just saying it's a shame that the beautiful patchwork countryside of my youth has gone.

An estimated 600,000 hectares of land are covered in the bobbing yellow flower heads, which were practically unknown in Britain 30 years ago. Production last year grew by 17 per cent and is predicted to top two million tonnes next year by the Department for Rural Affairs. For farmers it turns a healthy profit with unlimited demand for the seed as a biofuel - much of the UK's production goes to Germany to make biodiesel - and to make "extra virgin rapeseed oil", an alternative to olive oil.
