Development of farming skills-Part 2

My grand father's farming skill is more developed than the people from the movie. He uses many different tools to farm not his hands. He doesn't raise animals such as cows, pigs or other animals that helps to farm. Instead, he has a tool that can make a place to seeds go in and grow. But in the movie they do by their hands or animals.

Development Of Farming Skills

While I was watching this movie, I noticed that farming is very important. in Korea I can see my grandfather farming without any animals such as cows. They do farming by their farming tools. To compare with the movie and my grandfather's farming skills, many years ago, they did by hands but my grandfather uses tools like people from many years after like us. I also saw that how the skills developing. they also use animals like cows, pigs and etc. But this is differnt in New Guinea. They don't use any animals because they don't have in New Guinea.
