People of Burlington are being disturbed by the sound of bells. Four students from Burlington College of Higher Education are in the bell tower of the 36 and have made up their minds to 37 the bells nonstop for two weeks as a protest against heavy trucks which run 38 through the narrow High Street. “They not only make it 39 to sleep at night, but they are 40 damage to our houses and shops of historical 41 . ”said John Norris, one of the protesters.

“ 42 we must have these noisy trucks on the roads, ”said Jean Lacey, a biology student, “why don’t they build a new road that goes round the town? Burlington isn’t much more than a 43 village. Its streets were never 44 for heavy traffic. ”

Harry Fields also studying 45 said they wanted to make as much 46 as possible to force the government officials to realize what everybody was having to 47 . “Most of them don’t 48 here anyway, ”he said, “they come in for meetings and the Town Hall is soundproof, so they probably don’t 49 . It’s high time they realized the problem. ”The fourth student, Liza Vernum, said she thought the public were 50 on their side, and even if they weren’t, they soon would be.

I asked if they wer 51 that the police might come to 52 them.

“Not really, ”she said, “actually we are 53 bellringers. I mean we are assistant bellringers for the church. There is no 54 against practising. ”

Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use．This is especially true in agriculture, where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives．
To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so ．Medieval agriculture in northern Europe fed, clothed and sheltered a predominantly rural society with a much lower population density than it is today．It had minimal effect on biodiversity, and any pollution it brought about was typically localized．In terms of energy use and the nutrients captured in the product it was relatively inefficient．
Contrast this with farming since the start of the industrial revolution．Competition from overseas led farmers to specialize and increase yields．Throughout this period food became cheaper, safe and more reliable．However, these changes have also led to habitat loss and to diminishing biodiversity．
What’s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050，yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions．
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th．This will require radical（激进的）thinking．For example, we need to move away from the idea that traditional practices are inevitably more sustainable than new ones．We also need to abandon the notion that agriculture can be “zero impact”．The key will be to abandon the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage．Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used．There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity．It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting, but we do not know whether lower carbon footprints will always be better for biodiversity．
What is crucial is recognizing that sustainable agriculture is not just about sustainable food production．
