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 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 mainly rural society with a much lower population density than it is today. It had minimal effect on biodiversity, and any pollution it caused 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, safer and more reliable. However, these changes have also led to habitat loss and to reducing biodiversity.
　　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 thorough thinking. For example, we need to move away from the idea that traditional practices are certainly 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(稳定的)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 important is recognizing that sustainable agriculture is not just about sustainable food production.

Early in the 18th century, Captain Cook, a famous explorer of England, unexpectedly caught sight of an unusual animal during his first visit to Australia. The animal had a large mouse like head and jumped along on its large legs. To his great surprise, the unusual animal carried its young in a special pocket of flesh. Captain Cook pointed to the animal which was eating grass in the distance and asked his native guide what the animal was referred to. The guide seemed not to know what he was pointing at and finally said “Kangaroo”, but their requests were met with puzzled looks of the native people. Before long they got to discover that the native guide who made the answer to Cook's question really meant, “I don't know what you are pointing at. ” Funny enough, the name “Kangaroo”, stuck and it is still in use today.
