Two environmental activists who surprisingly took over the tower crane in Haman dam spent a harsh summer without food or water, while managers in the construction site and the police refused to provide them. The place where they climbed up, risking their lives, is called 'Sky Garden.' Worse then the heat and hunger was to witness everyday how people razed the river.

Although Nakdong River provides water to most of populations in Yeongnam area, the general public does not know, or is indifferent in the process and results of the destruction of Nakdong River. As a consequence, a radical way to prohibit the ongoing construction in Nakdong River appears. It is important to display two opposing arguments and to unravel why environmental activists are protesting.
