"People who move to live near a farm, do so aware of the problems associated with an activity which has taken place on that site, often for hundreds of years. Is it suggested that farms stop operating because these new neighbours object to the normal processes? "

Don't bank on it, we once had a pig farm in the country which was surrounded by houses and then closed because of the offensive smell. Residents refused to pay their rates till the council sorted out the smell, the hassle caused us to give up, the buildings were wrecked by yobs and the land is a fly tippers heaven. (we rented the land from the council)
