Britain was the first highly industrialized country and for a long time it led the world in industrial production. In 1870 Britain made one third of all the world's manufactured goods.
From about 1870, however, Britain began to lose its lead. Today Britain produces 11% of the world's exported manufactured goods. Britain needs to expo~ to pay for all the foods it needs.
The country is the fifth most densely populated in the world. It has a population of 59 million people on a number of islands.
There just is not enough room to grow food for all these people even though British agriculture is one of the most mechanized and most advanced in the world.
