The Niagara Falls have a total height of 167 feet with three separate waterfalls that delineate the border between Canada and the United States. According to estimations, in approximately 50,000 years the Niagara Falls will cease to exist due to soil erosion. As of 2014, Niagara Falls is the largest producer of electricity in the state of New York. In 1950 Canada and the United States signed a treaty limiting the water usage by the power plants to maintain an uninterrupted flow of water and the natural beauty for tourists to enjoy. As of 2014, four people have survived a jump from the top of the Niagara Falls without protection.
