"The introduction of modern agriculture meant many different changes." Describe in four points

The dramatic expansion of agriculture was made possible by new technology. This meant many new changes as follows
(i) The open field disappeared. The increase in food production was not only possible by radical innovation in agricultural technology, it also needed new lands under cultivation.
(ii) The richer farmers expanded grain production, sold this grain in the world market, made profits and became powerful. -
(iii) Modern technology and enclosure displaced the poor from the land. The poor found that their customary rights were gradually disappearing. Deprived of their rights they moved in search of jobs.
(iv) The poor left their village. They went to countries or cities where job was available, but jobs became insecure. They lived in fear of the loss of their livelihood.
Thus, we can conclude that the introduction of modern agriculture meant many different changes.
