During the Middle Ages farming was the basis of society. Every one of the feudal system - the lord, servants, and retainers - was supported by the income that came from farming. So the exploration of land was extremely important which caused a huge environmental impact.
The problem was that in that time there was no agricultural improvement, they did not know how to enrich the soil or how to do the proper rotation of crops, they used the system that cultivated 2/3 of the land and let the other third to rest. This caused a series of impacts such as climate changes, deforestation, and soil erosion.

The linguistic, political and geographical differences between both sides were related to the division of the Roman Empire in 395. In the Roman Empire, the emperor and political power moved from Rome to Constantinople; this also brought about changes in the spiritual climate of the kingdom. Tradition had hitherto offered that the emperor would have authority in both worldly and spiritual matters. Those who strongly adhered to this principle came to be on the orthodox side of the conflict, while those who clung to the bishop of Rome (the Pope), who has always been the foremost ecclesiastical potentate, came to be on the Catholic side in the conflict.
