Working hard in order to work at a full-time farmer is hard work. These agricultural workers must participate in intense manual labor when entering the farm. To make matters worse, in order to complete the work normally, it is necessary to take a health risk on each task. Work such as pulling rhizome crops from the ground and bending cereals from the ground is just one example of farmers' reactions. In this case, the farmer's price is a risk of long-term back pain because the bending time is too long or the hand is pulling so as to cause the hand to hurt the surface.
First, let's look at the Industrial Revolution. According to Britannica Encyclopedia, the Industrial Revolution is a process of "conversion from agriculture and handicraft economy to industrial machinery manufacturing economy". It began in the 18th century in the UK and then spread to other parts of the world. Technological changes include the use of new basic materials mainly steel and the use of new energy sources such as fuel and electricity such as coal, steam engine, electric power, oil and internal combustion engines, rotation Jenny and power room The invention of the machine is included. A new working organization that makes it possible to increase production with less effort is called a factory system.
At the beginning of the 18th century, the invention of the first modern steam engine told the transition from agricultural economy to industrial economy. Steam engines can be moved with wood or coal, but coal rapidly turned into optimum fuel, resulting in a significant expansion of industrial scale. Half tons of coal is cheaper to produce and produce four times the energy of the same amount of trees. Coal fired steam locomotive dramatically reduced the time and cost of land transportation, steam ship crossed the sea. Coal machines realize dramatic improvement in productivity while reducing manual labor
