Sustainable farming is the production of high quality food, fiber or other plant or animal products using farming techniques that protect the environment, public health, human communities and animal welfare. The main objective of sustainable farming is utilising limited resources in such a way that a part of it is kept in reserve for the future generation. Non-renewable resources are of more economic value, as these cannot be readily replaced by natural means on a level equal to their consumption. Most fossil fuels, such as oil, natural gas and coal are considered as non-renewable resources, as their use is not sustainable because their formation takes billions of years. Thus, sustainable farming aims at production of high quality goods with minimal use of resources and also ensures safety of farm workers, local communities and society by using those control measures which affect the environment.
