One of the world's largest hydroelectric power plants is the Three Gorges Dam located in China, which is two and a half kilometers wide and 185 meters high. It creates a lake on the river with a flooded area larger than Budapest. While dams provide continuous energy production, massive construction projects, however, take victims as well. Damming the river comes together with flooding extensive areas, where thousands of people are losing their homes, and hundreds of animal species disappear forever.

The Rose of Jericho is a desert plant, which is able to live for long years without water even in hot dry sand dunes. The secret of the plant's amazing survivability is that on hot dry days it dries out as a small ball-shaped dry weed, then it sets sail with the wind, and wanders until water is found. After receiving water, the plant starts getting greener and taking roots in minutes.
When the moisture disappears, the plant dries out and starts to wander with the wind again, even through several kilometers.
