Farming still has a bright future despite the "constant attacks" of politicians, super-markets and anti-fox hunting activists, an MP has claimed.
Peter Luff (Con Mid Worcestershire), Chairman of the Three Counties Agricultural Society, said British farmers would remain at the heart of the nation's food industry despite the threats they faced.
He also called on the Government to make more use of bio-fuels. But he warned that farmers must also be willing to adapt to the globalised market.
In a speech to farmers, Mr Luff said: "Some people would have us believe that farming is a has-been industry.
"The result, on top of the real regulatory and financial pressures facing the industry in 2006, is a damaging lack of self-esteem among farmers who feel themselves under constant attack - from environmentalists, animal rights activists, supermarkets, politicians and government.
"Puzzled and confused by conflicting and ever-changing messages and demands, many are feeling angry and isolated.
"The hunting ban may not have been the most important issue for the business of farming, but it symbolised what many in the countryside saw as a complete lack of understanding of the rhythms and customs of rural England and Wales."
However, farming continued to have major economic significance, he said.
"British agriculture provides much of the raw materials for the rest of the food sector - wholesaling, retail-ing, manufacturing, and catering.
"The whole UK agri-food sector was worth £78.2 billion in 2004, a huge slice of the national economy."
Food manufacture was the single largest manufacturing sector in the UK, he added.
"This large British food industry, a crucial part of our nation's economy, part service, part manufacturing, is and can remain under-pinned by British food production by British farmers - but only if farmers respond in a sensitive but business-like way to their opportunities.
"A globalised world means no one has the automatic right to produce anything. Government and farmers will both have to be fleet of foot if British farming is to prosper.
"It's not just about food. Other markets for British farmers look set to emerge too.
"Sensible government policies on bio-fuels could steadily expand the market for fuel crops.
"After all, this would only return us to the relatively recent past, when something like a third of all farm land was used for fuel crops - hay and oats for horses."
Mr Luff gently rebutted claims by fellow West Midland Conservative Bill Wiggin (Con Leominster) that polytunnels were ruining the countryside.
Mr Wiggin - the Conservative shadow Agriculture Spokesman - has been attacked by farmers for announcing he is boycotting any English strawberry grown out of season, on the grounds that it was probably grown in a polytunnel.
But Mr Luff suggested farmers had no choice but to use them.
