Sinkholes, Disappearing Lake Threaten South Korea's Lotte World Tower Skyscraper [VIDEO]

South Korea's Lotte World Tower, which was designed to be one of the tallest skyscrapers in the world upon completion, is being threatened by the sudden appearance of sinkholes in the area. The sinkholes, which are destroying streets in the surrounding residential area, come as a nearby lake has also begun to disappear, two problems that could delay construction of the skyscraper indefinitely.
