Background

In the early to mid 1900s, China built a dam to help increase the use of hydroelectric power. This started to cause problems because it put a halt to transporting goods through the river. Even though it had blocked transportation, with the dam there, they were able to treat about 7,664.5 tonnes of solid waste every day. With this, the water was cleaner and more efficient. The people who were affected were mainly just the civilians in the area of the dam that couldn't get any goods transported to them from one side of the river.
