You have wondered where the world's sewage treatment system and the idea of aqueduct come from; some of the most common inventions in the world come from a place called Rome. At the turn of the 20th century, Rome had more paved roads and then unleashed the state. Rome also has the first known sewage system. In order to supply water to Rome, they built a number of canals still in use today. Due to devoted efforts to Roman citizens, sewers, waterways, roads of the 20th century may not be here today.
Another factor that led to the decline of the Roman Empire was that during the past 400 years of the Empire the scientific achievements of the Romans were almost exclusively limited to the organization of engineering and public service. They built wonderful roads, bridges and waterways. They established the first health care system for the benefit of the poor. But since the Romans were heavily dependent on the labor of people and animals they failed to invent many new machines or to find new machines to produce products more efficiently. They can not supply enough goods for population growth. They will no longer conquer other civilizations and adjust their skills and they are actually losing an area they can no longer maintain in the corps
The Roman Empire was ruined, but their heritage is known today for their numerous achievements in art, architecture, writers, languages and citizenship. But during the last 400 years of that empire, some people thought that the inability to innovate their new technology is a major factor in the demise of their empire. The results of their early engineering sciences brought long-lasting paths, bridges, and waterways. Their public service organization helped establish the first medical system that brought benefits to the poor. However, "Because the Romans depend heavily on human and animal labor they can not invent many new machines nor can they find new technologies to produce goods more efficiently "(Bower et al., 1993). Their dependence on outdated, ultimate, inferior production technologies prevented them from offering all the goods and services they needed for the rapidly growing population.
