But in some places, people must carry gallons of water from the closest stream, river, lake, or well to their homes

Answer 2

Answer:

The sources and availability of water in the past and those in the present have been compared and contrasted.

Explanation:

Humans consume a lot of water. It is required for a variety of activities such as agriculture, transportation, washing, and recreation. Most importantly, humans must drink clean water in order to survive. Fresh water is now delivered directly to where we need it in many parts of the world. But, in certain areas, residents must transport litres of water from the nearest stream, river, lake, or well to their dwellings.

Water access and the ability to carry water from its source to where it is needed are critical concerns for any society deciding where to build their houses and towns. This has always been the case. Ancient villages, towns, and cities were built near bodies of fresh water such as rivers, lakes, and oasis. Also, reservoirs and tanks were frequently constructed to collect rainwater.

Archaeologists have discovered remnants of numerous historical water circulation systems. Canals, pipes, sewers, wells, and, perhaps most notably, aqueducts are examples of these. The term "aqueduct" comes from the Roman words aqua, which means "water," and ducere, which means "to lead." Aqueducts were designed by the Greeks and improved by the Romans to convey water downwards via channels from fresh water springs to towns kilometres below. Water travelled via tunnels, over channels supported by walls and arches, trenches, and pressurised pipes on its way from source to city.

Nowadays, rivers and streams provide two-thirds of all drinking water in the United States. Water is treated, tested, and purified at a facility to verify that it is safe to drink. The water is then piped underground to homes, schools, and businesses.
