Farming in Britain has changed a great deal in the last 30 years. Farming used to employ a great many people in Britain but nowadays, with machinery, a few people can run a huge farm of thousands of hectares.
    Agriculture provides around 60 percent of Britain’s food needs even though it employs just 2 percent of the country’s labor force. Britain’s agriculture is under pressure to change at the moment. Farmers are under pressure to adopt more environmentally friendly methods such as organic farming. Organic farming does not use artificial chemicals that can damage the environment and human health. Its popularity has grown rapidly in recent years. Different types of farming occur in different regions of Britain. This is due to the influence of relief, climate, and soil type and to an extent closeness to the market. Upland areas generally lend themselves to sheep farming. Flat areas to crop production and wet/warm areas to milk and beef production.
    Some parts of Britain have excellent soil for crops, while others are used for cattle, sheep, pigs and poultry.
    In the northwest of England, Wales and Scotland, farmers keep cattle and sheep. Sheep can survive the cold winters on the hills and moors.
    In the southwest of England, the rich grass is ideal for feeding dairy cows.
    In the southeast of England and the lowlands of Scotland, grain, potatoes and sugar beet are grown.
    In East Anglia (Norfolk, Suffolk and Essex), wheat, barley and vegetables grow in enormous fields.
