Agriculture can be defined as the cultivation of land and breeding of animals and plants to provide food, fibres, medicinal plants and other products to sustain and enhance life. It has been credited as one of the main contributors to the rise of sedentary human civilisation, wherein people settle in one area for longer periods of time. Agriculture dates back thousands of years. The field of agricultural science is fast developing and is having large ecological and environmental effects. A degree in agriculture will allow you to understand the scientific, logistical and environmental aspects of crop and animal production.
