Agricultural revolution
In the Earth's history there have been a number of agricultural revolutions. The term is quite vague, however, and many claims of revolutionary change are contested by some economic historians.
Agricultural Revolutions:
- Origins of agriculture - (perhaps 10000 years ago) - forms the basis for human civilization to develop.
- British Agricultural Revolution (18th century) - helps launch the Industrial Revolution
- Scottish agricultural revolution - leads to the so-called Lowland Clearances
- Green Revolution (1945- ) use of industrial fertilizers and new crops greatly increases the world's agricultural output.
