During the 17th century, New York began to thrive with its new innovations and economy which had begun to grow at an exponential rate. The Erie Canal set New York in motion for generations, allowing for the rest of the country to gain easy access to the hub that is new york. Trade businesses grew because of the direct access to Albany as well as buffalo. Because of the new found success in the west, expansion spread towards the eastern side of the country, as well as allowing for immigrants to start to make their mark in the country, further embellishing their future for generations to come. With this new mode of transportation and trade, this inspired even further innovations such as steam power as well as railroads making even greater connections within the area. Traveling distances had more than halved, and cost travels had dropped drastically as well. Several jobs had been created boosting trade, immigration, as well as an overall outlook on the success of the country. From this, population had skyrocketed increasing apartments and tenements, sadly in turn, this had introduced an unhygienic city and filth and disease had spread within the city. Within small tenements and apartments, hygiene was very hard to control especially due to their overpopulation. Conditions would be so bad, as to host 10-20 people per tenement. Within these conditions, all these people would share one bathroom. Cleanliness hadn’t become such an important issue until a few years later. All of these are evidence that one advancement leads to another.
