But in present, only 2% of the population produces food for the whole world to eat. That is a big change in the amount of food producing associated with people and assuring that everybody has sufficient food to eat.In earlier days farmer used animals for field work and It take long time to complete their work in fields Therefore farmer worked on small piece of land. Animals were not very fast, and they would get tired soon and need some rest side by side to recover from their hard work.
