changes that is happening

The most important of the changes that is bringing about the Industrial Revolution are (1) the invention of machines to do the work of hand tools; (2) the use of steam, and later of other kinds of power, in place of the muscles of human beings and of animals; and (3) the adoption of the factory system.

It is almost impossible to imagine what the world would be like if the effects of the Industrial Revolution were swept away. Electric lights would go out. Automobiles and airplanes would vanish. Telephones, radios, and television would disappear Most of the abundant stocks on the shelves of department stores would be gone. The children of the poor would have little or no schooling and would work from dawn to dark on the farm or in the home. Before machines were invented, work by children as well as by adults was needed in order to provide enough food, clothing, and shelter for all. 

The Industrial Revolution came gradually. It happened in a short span of time, however, when measured against the centuries people had worked entirely by hand. Until John Kay invented the flying shuttle in 1733 and James Hargreaves the spinning jenny 31 years later, the making of yarn and the weaving of cloth had been much the same for thousands of years. By 1800 a host of new and faster processes were in use in both manufacture and transportation.

This relatively sudden change in the way people live deserves to be called a revolution. It differs from a political revolution in its greater effects on the lives of people and in not coming to an end, as, for example, did the French Revolution.

Instead, the Industrial Revolution grew more powerful each year as new inventions and manufacturing processes added to the efficiency of machines and increased productivity. Indeed, since World War I the mechanization of industry has increased so enormously that another revolution in production is taking place.
